3 Some reasons to discuss these topics with Fujitsu Fujitsu has a very long history in the topic of server virtualization more than 40 years. It started with virtual machines in our mainframe offering, GlobalServer and Fujitsu s BS2000, which still are available. Knowing server virtualization technology and its benefits from the beginning, Fujitsu has also completed thousands of x86 server virtualization projects successfully. Fujitsu also transferred its experience as one of the world s leading cloud service providers in helping customers to build their cloud environment. This is proven by many current success stories and Fujitsu s contributions in in private cloud programs from our technology partners like Intel and Microsoft. Also Fujitsu s products, such as FUJITSU Server PRIMERGY and FUJITSU Storage ETERNUS benefit from the comprehensive experience as service provider and system integrator. PRIMERGY server and ETERNUS storage systems are optimized for x86 server virtualization and cloud infrastructures among others by using the latest technologies, certain features and maximum compatibility with market standards as proven by many benchmark records. Moreover it is also worth mentioning the integration of server virtualization in Fujitsu solutions and Fujitsu s offerings that extend virtualization. One example of the use of server virtualization within complete solutions is FUJITSU FlexFrame Orchestrator an entire solution for SAP environments. FUJITSU ServerView Resource Orchestrator is an example of an extended server virtualization offering. It allows the uniform management of a mixed environment even if different server virtualization technologies are used or if it is a mix of virtual machines and physical servers. That is complemented by the offering of complete pre-configured and preinstalled ready-to-run converged solutions like Fujitsu Cloud Ready Blocks which, besides its further benefits of a converged infrastructure, enables a very short time-to-production. Not to forget Fujitsu s data protection appliance FUJITSU Storage ETERNUS CS, harmonizing and optimizing entire backup and archiving scenarios. A further essential argument why you should deal with Fujitsu in the area of server virtualization and cloud computing is Fujitsu s complete service offering. This service offering for all aspects of server virtualization and including any kind of cloud services starts with pre-defined and fixed price assessment services to analyze the current customer situation and to provide customers with re commendations about how to proceed with their IT. Among others, these OPTIMIZATION Services are available for cloud computing and server virtualization. Beside these consulting services, ROI/ TCO estimations, design services, delivery services, operation services, product/solution-related services, various managed services and financial services are also available. Fujitsu s close cooperation with all market leaders in virtualization and cloud technologies puts us into a position to be the reliable advisor of our customers. For some similar technologies we deal with different partners for example on the server virtualization layer with Citrix, Microsoft, SuSe, Oracle, RedHat and VMware in order to have an appropriate solution for any customer requirement. Moreover, it should be mentioned that Fujitsu is the only server manufacturer today that develops and produces its x86 PRIMERGY servers in the heart of Europe. One further argument, especially for global customers, is Fujitsu s capability to serve customers worldwide with all levels of expertise, products and services. Our follow-the-sun call centers support more than 25 languages. Page 3 of 42

4 x86 server virtualization What is virtualization? Within the IT industry virtualization is used between today s standard interfaces to abstract different layers from each other. Because of defined and comprehensive interfaces the dependencies of different IT layers (e.g. the server hardware and the connected network infrastructure) are very strong and often result in inflexibility and low utilization. For example: When one layer is updated, the other one needs an update, too. When one layer is defined, the upper and lower layer often can t be used for anything else. To overcome these strong dependencies an additional layer the virtualization layer can be inserted. As today s IT has many defined layers, the possibility of inserting separation layers between them is also varied. Just to name some of the resulting virtualization technologies: I/O virtualization Server virtualization Network virtualization Application virtualization Storage virtualization Client virtualization Operating system virtualization... Many IT installations during the past years often contained more than one of these technologies in order to combine their related benefits and to achieve a state-of-the-art, dynamic IT infrastructure. In terms of this document we are focusing on x86 server virtualization. What is x86 server virtualization? As the title indicates, x86 server virtualization describes the virtualization layer between x86 architecture-based server hardware and the associated operating system. This virtualization layer is usually called the hypervisor. This hypervisor isolates the x86 server hardware from the various operating systems. The server hardware sees it as its operating system and provides the known operating systems with the capability to use pre-defined portions of the available x86 hardware resources. Those portions are called virtual machines (VMs) and are fully isolated from each other. They do not even know each other. This enables the sharing of server-hardware capabilities between different operating systems and applications. The core tasks of a hypervisor are: Foundation to operate VMs Separation of the VMs from each other Efficient distribution of resources between VMs in line with the administrator s specifications Mapping of machine instructions issued in a VM Mapping of I/O jobs The indirect advantage of a virtualization layer By adding an additional layer as an interface between the server hardware and the operating system, a further major advantage can be achieved: it is possible to influence their communication. Said influence never means modifying anything, but it enables time shifting and even more important sharing of information. Transferred to server virtualization this means that memory and CPU states of a virtual machine can be copied to another server. The result is one major feature of using hypervisors: Live Migration (aka as VMotion, XenMotion, ) of virtual machines (including operating system and application) without any interruption from one server to another one This is the fundamental technology used for many further automation features provided within hypervisor management. Page 4 of 42

5 Preconditions to the effective use of server virtualization In addition to the very obvious components of a virtualized infrastructure: hypervisor, its management and appropriate x86 server hardware (optimized server virtualization support, fitting I/O connections) centrally accessible storage is also an elementary component. To make use of the high availability options e.g. restart of a virtual machine in case of a hardware failure on a different server the server inevitably needs access to the data of that virtual machine where it should be restarted. So typically storage consolidation has to be done first, before x86 server virtualization is introduced/expanded to leverage all the capabilities provided by this technology. This can either be done with central storage systems or by using storage virtualization (e.g. of local discs within the server) which provides similar capabilities. How to manage hypervisors? As can be imagined, the hypervisor itself has to be a lean and very efficient piece of software. Therefore, to provide little or no surface for security attacks the hypervisor itself is optimized to support its basic functions and to move all resource-intensive tasks (e.g. management via GUI, automatism, rules, ) to outside management software. This management software takes care of the entire management of the hypervisor AND the virtual machines. It allows comprehensive management of the hypervisor and virtual machine capabilities. Every hypervisor vendor provides its own management software, which partly is also able to manage hypervisors/virtual machines from other vendors. But usually you get the best results and access to the full set of features if the management software of the hypervisor vendor is used. To have an indication of pure hypervisor size it should be noted that for example vsphere ESXi from the market leader VMware has a size of approximately 150 MB. Format of virtual machines Due to the fact that the variable hypervisors are based on technically different sources, a virtual machine generated for one specific hypervisor would not be able to be operated on the hypervisor of another vendor. To overcome this problem and to enable appliances (the application ships as part of the virtual machine and not in conventional installation format) all major hypervisor vendors support the OVF (Open Virtualization Format). By using this format the respective virtual machine can be executed on different hypervisors without any changes. However, by using this format (standardized by Distributed Management Task Force, Inc. short DMTF) some specific features provided by just one vendor probably can t be leveraged for the VM in OVF because it is standardized. In the past and also likely in the future this results for some customers in the need to operate more than one hypervisor type in their data center. Performance impact of the hypervisor Inserting an additional layer often gives the impression that everything gets complicated and more power is needed. This partly applies also for x86 server virtualization, BUT x86 servers have had a tremendous performance boost for many years, which is still continuous The average utilization rate of x86 servers without using server virtualization is usually below 15% Today s x86 servers and their used components are optimized for server virtualization Nearly all hypervisors are stable and performance-optimized in various ways This results in the overall message that the typical performance impact of much less than 10%, if real-time operating systems are not used, can be disregarded.

6 Benefits of server virtualization Customers can achieve many business benefits by using server virtualization. The technology in principal might not be new, but it has never paid off on such large scale. First, for most implementers the achievable consolidation ratio was the key motivation to introduce server virtualization within their company. When customers are able to replace 15 (or even more) old servers with one new server that additionally needs less power than one of the old servers, this results in tremendous savings in investment costs (CAPEX) and operating cost (OPEX energy, space requirement and management). Additionally, the homogenous virtualization layer allows customers to run old operating systems on new hardware. The example often used is Windows NT, which is already out of any Microsoft support and certification program and which is executed in a virtual machine running on the up-to-date Fujitsu PRIMERGY generation. Any virtual machine can also be implemented on any virtualized server hardware, which provides very flexible use of all x86 resources. Many automation functions could be implemented with the option of live migration of workloads from one server to another. For example, power-optimized use of servers while all applications are up and running: if the applications are only rarely used, they can be aggregated on a few servers and the remaining servers could be switched off. When more compute performance is needed, an appropriate number of switched-off servers would be powered-on and the applications in the virtual machines would be live-migrated to the powered-on servers all of that fully automatically and without any interruption of the application. Similar things apply for hardware maintenance windows: zero downtime. Software deployments also get much easier: a virtual machine does not need to be active the management of the hypervisor can also update offline machines. Likewise all hypervisor vendors provide convenient tools to run automatic updates of all affected machines or duplicate existing virtual machines or templates. A new service can be up and running with just a few mouse clicks. Not to forget the very easy scalability. As mentioned above, there are many options to lower the number of powered-on servers. The opposite, e.g. extending a virtualized environment, just needs an additional server with the appropriate hypervisor. Just connect the server to the network and it can be integrated in the overall environment with a few mouse clicks. All of that is complemented by the integrated and uniform high availability concept that comes with using server virtualization. In the past it was often very complicated to set up high availability solutions, because many of them had application or operating-system-specific dependencies and were mostly associated with an additional license fee. By using server virtualization all hypervisor vendors enable an integrated, application and operating-system-independent concept: if a server fails or can t be contacted, all virtual machines can depending on the predefined settings automatically be restarted on another server. This is uniform for the complete virtualized environment. On top of this, you can add mechanisms which control the applications to extend this general capability to an application-aware feature. To avoid misunderstandings: traditional clusters still work when server virtualization is used. Can everything be virtualized? Unfortunately not everything can be virtualized with server virtualization. All servers produced today include virtualization-optimized features. But servers bought more than 5 years ago probably do not support all capabilities of a hypervisor and its management. Also certain I/O cards (e.g. dongles, fax cards, special graphic cards,...) can t be used with x86 server virtualization. Which components are supported can be seen in the hardware compatibility list (HCL) of the various hypervisor vendors. The number of unsupported and currently available components is getting smaller and smaller. Market acceptance of server virtualization According to hypervisor vendors and many analysts more than 70% of all workloads of x86 servers are running in virtual machines today. Moreover, also according to statements from IDC, Gartner and Forrester, the market share of Fujitsu s hypervisor main partners, Citrix, Microsoft, SuSe, Oracle, RedHat and VMware, together is big- Page 6 of 42

7 ger than 99% of all hypervisors used in business. The top three in the ranking with regard to the number of virtual machines running on which hypervisors are: 1. VMware 2. Microsoft 3. Citrix Server virtualization and cloud computing The capabilities of server virtualization, especially its great benefits with regard to flexibility, uniform SLAs, automation options and scalability, can be perfectly used to deliver the foundation for cloud computing. This does not mean that any kind of cloud computing always relies on server virtualization, but it can be seen as one of the key enabling technologies for it. The picture below describes the movement of customers from virtualization towards cloud computing and the logical steps in between. Server virtualization, what else? As already stated in previous sections, x86 server virtualization is a mature technology which naturally also expands its functions in associated areas. The main areas today are storage virtualization, network virtualization and cloud management. With cloud management all kinds of cloud computing: private, hybrid and public clouds are addressed. Overall this development results in many nice features, formerly known from separate tools and vendors only, can easily be accessed by additional licensing options of the server virtualization layer and its management. Meanwhile all hypervisor vendors have an offering beyond pure server virtualization and these offerings merge together. This also applies for Fujitsu with offerings that extend virtualization described in further sections of this document. Any kind of cloud computing, whether private, hybrid or public clouds, is more than the extensive use of server virtualization. However, server virtualization is often one step towards cloud computing, which needs many more capabilities to be implemented. All hypervisor vendors work on their own cloud stacks to enable customers to build their own cloud solutions. Moreover, they offer integrated tools for uncomplicated access to cloud services from own or publicly available offerings to also leverage the benefits of these cloud offerings. Page 7 of 42

8 Private Clouds What is cloud? Fujitsu defines cloud as the consumption of infrastructure, an application, an activity or content of which that consumption comprises three distinct attributes: Pay per use Elastic and scalable Self service Clouds are usually available in four different formats: Private Cloud is dedicated for one customer. Community or Trusted cloud is for serving a number of selected customers. Public cloud is for (theoretically) every customer. Hybrid cloud is any combination of the three others. Each format could provide services with the three distinct attributes. The most popular services today are: IaaS, Infrastructure-as-a-Service: providing server, storage and/or network capacities to its users (e.g. system administrator) PaaS, Platform-as-a-Service: providing operating systems and software development tools including the necessary IT infrastructure to its users (e.g. software developer) mostly used to provide SaaS later on SaaS, Software-as-a-Service: providing the ability to use software to its users (e.g. any user needing the software) BPaaS, Business-Processes-as-a-Service: providing the use of complete business processes to its users (e.g. logistics manager) Cloud: Consuming IT as a Utility Private just for you Elastically Scalable Pay per use Community selectively shared Hybrid a combination Self Service Public shared with anyone IaaS PaaS SaaS BPaaS From the user perspective, the technology and the how to issues usually associated when a new service is needed are completely taken away. Users of cloud services can fully concentrate on their core business and do not have to deal with daily IT operations because of the standardized and automated processes coming along with cloud computing. Just to give you an example: by using the cloud independent of whether this a private, public, community or hybrid cloud, but depending on the service offered, see examples above a catalog with predefined services is the starting point. Access is realized via a self-service portal where the user can apply for the requested service. After the user has found its appropriate service and applied for it, an acceptance/rejection workflow runs automatically. If the request is accepted, the user can access the service according to the description of the catalog. In addition to the functional description of the service, the aforementioned service catalog also contains information on the pricing (based on use time), term and time of payments and the quality description of that service: like availability time a year, recovery time, frequency of backups (if any) and many more. Last mentioned examples are called Service Level Agreements, in short SLA. Summarized, the user of a cloud no longer has to take care of technology and how to set it up the user can pick any available service, just use it when it is needed and only has to pay when the service has been used. What is Private Cloud? Private Cloud is a cloud environment that only serves one single customer. It is operated in two different ways: Private Cloud on-premises means the operation of your cloud in your data center with your IT infrastructure Private Cloud off-premises means the operation of a dedicated (again, just for you) as-a-service offering in the data center of your cloud provider As the cloud environment in both cases is dedicated to you and your needs, it is obvious that the key criteria for cloud computing again: pay per use, elastic and scalable, self service are difficult to match in full. For example, the benefits of pay per use, if you have a private cloud on-premises, might not be matched in full because you are still the owner of the entire IT infrastructure and there are investment and operation costs; more or less independent of how much capacity is used. On the other hand you have much better options to take influence on everything in that cloud, including the definition of SLAs and how to handle your data in detail. In terms of this document, Private Cloud is Private Cloud on-premises. Page 8 of 42

9 Preparations for the effective use of Private Clouds Before transforming your IT infrastructure into a Private Cloud or setting it up from scratch, a detailed analysis of the business processes within your company has to be undertaken. This has to include how your individual short, mid and long-term targets can either be achieved by: Extended use of virtualization technologies and associated automation tools Private Cloud environment on-premises Community or publicly available as-a-service offerings Otherwise, you could possibly implement a Private Cloud environment and the achievements do not match your expectations. How to manage Private Clouds? The management of Private Clouds needs the same principle architecture as the management of any cloud. In general this is: The word service in the picture above, stands for that kind of service that should be provided by the Private Cloud to its users: infrastructure, platform, software or business processes. All management software components have to be integrated with each other to achieve a complete cloud solution. Today several tools are available for Private Cloud computing, e.g. Fujitsu ServerView Resource Orchestrator Cloud Edition, which is described in a separate section of this white paper. In addition and as already mentioned in the section on server virtualization, complete cloud management tools are available from hypervisor providers and also from management software companies. To have the optimal solution for our customers and their needs, we complement our portfolio with these solution stacks. Some of these tools, e.g. VMware vcloud Suite, also allow managing resources from community or public cloud offerings and thus lead to comprehensive management of your complete hybrid cloud environment. Benefits of Private Clouds The three distinct attributes of cloud computing already indicate the benefits of Private Cloud computing. In particular, these are: Ease of use Cost savings and cost transparency Very flexible use of IT resources Ease of use is achieved by the general structure of a cloud. The necessary and strict multi-tenancy (in Private Clouds these are often different departments of your company), the standardized service level (SLAs) and the self-service portal build the foundation to fit this benefit. It can be even improved by using further automation functions, well defined and prepared (e.g. SLAs) entries in the service catalog and by the provided services covering as much as possible of the tasks of each user, e.g. by providing Software-as-a Service instead of providing Infrastructure-as-a-Service for the respective user depending on the needs of the user. Lower costs result from the shared infrastructure of a Private Cloud. For example, peak requirements of one department, often responsible for too many installed/assigned infrastructure components, can be absorbed by temporary assignment of free resources (e.g. compute power) when they are not needed by other users/departments. Thus, the average utilization rate is much better than before thanks to sharing the available resources between all users in a still separated (catchword multi-tendency ) way. Moreover, the elements responsible for the ease of use pay off again, because the users and administrators as well are freed from day-to-day routines and can focus on their key tasks. All of that is fully transparent through the metering and accounting functions of the cloud management layer and so avoids any fruitless discussions between departments when it comes to covering the IT costs. Generally, it could be said that as more services of a similar kind are provided by a Private Cloud the bigger the benefits are. But also the inclusion of public or community cloud services to your Private Cloud enhances the aforementioned benefits. Page 9 of 42

10 Can everything be brought to the Private Cloud? Comparable to server virtualization, not every service or task can be operated in a Private Cloud. Again, depending on what kind of service should be provided, there might be major adoptions necessary. Let s take Software-as-a-Service as an example. If you have the goal to provide SaaS for certain applications, these applications need some capabilities to be provided as-a-service and also need the appropriate Private Cloud management stack. Operating the application without any adaptations or special management software in an IaaS environment would not provide the requested result. Beside technical issues license costs which blow your budget could also occur. Nevertheless, because Private Cloud environments are accepted in the market (see Market acceptance of Private Clouds ) and also because nearly all established software providers and likewise many startups are extensively pushing this technology, the number of unsupported services is getting lower and lower. Performance impact of Private Clouds Obviously a Private Cloud needs an additional management layer, see section How to manage Private Clouds? Most components of that management layer are not needed all the time thus they only need small resources when they are executed. The always-on management software components, e.g. the metering tools, are optimized to have very little impact on daily operations. Today, the technology used to build the various Private Cloud services, whether it is IaaS, PaaS, SaaS or BPaaS, is different. This combined with various management options makes it very difficult to disclose exact figures on the performance impact. But the experience we gained with our own cloud service offerings and within our customer projects, where we supported our customers with the building of their Private Cloud, results in the overall message that the typical performance impact can be disregarded mostly independent of what service is provided. Market acceptance of Private Clouds According to various analysts Private Cloud computing will be used at least for parts of their IT/business by more than 40% of all enterprises. The clearly most popular service provided by Private Clouds is Infrastructure-as-a-Service; this also applies in productive use. The reason why IaaS is the most accepted service (again, within Private Clouds) is in the available offering for the required management stacks. The IaaS Private Cloud management stack is today the most complete and commercially available Private Cloud solution. As indicated in the comparable section of server virtualization, where VMware is the market leader, it is mainly used as the basis for IaaS services in Private Clouds. So it is no surprise that VMware is also the market leader in Private Cloud management stacks for IaaS. An extended IaaS is often used to provide PaaS via Private Clouds. When it comes to SaaS, mainly application-specific solutions come into play nowadays. The same applies for BPaaS. One example of SaaS Private Cloud solutions is our FlexFrame Orchestrator, which is described in the section SAP-aware IT infrastructure. Summarized, it could be said that market acceptance for Private Clouds is high. Moreover, Infrastructure-as-a-Service is dominant today, but the other service offerings are evolving very strongly and especially SaaS will, when it has greater maturity and broader-based offerings are available, surpass IaaS in Private Cloud computing. Risks of Private Clouds Just as with benefits, which are in part difficult to achieve in full, the commonly discussed risks of cloud computing usually do not apply in full for Private Clouds on-premises. One of the main reasons holding back universal adoption of cloud computing is security. Being based on the Internet does make cloud computing susceptible to cyber attacks, but Private Clouds are operated within your firewalls and that makes them at least as secure as your infrastructure was before. When a company has its data in the cloud, it is not under its direct or physical control and due to the respective, applicable law other governments may have the right to view that data (e.g. in U.S. or with U.S.-based companies as cloud providers). However, Private Cloud on-premises hosts its storage capabilities in your data center, which is fully under your control. So you decide on the accessibility of your data and how it will be protected. We could extend this section by many other points but they key message would not change: most possible risks of public cloud computing are under your full control by running a Private Cloud environment. Therefore, the risk of your Private Cloud is your responsibility and depends on the SLAs you implement for your solution. Page 10 of 42

11 Private Clouds and server virtualization Server virtualization is often used as the key technology in the area of Infrastructure-as-a-Service offerings in particular, but also for Platform-as-a-Service offerings. The described capabilities of server virtualization, enhanced with a serious Private Cloud management stack, are a validated combination that is often used today. It can also be said that the broad acceptance of server virtualization and its automation paved the way for cloud computing, especially with regard to IaaS. For the remaining cloud services server virtualization can be seen as enabling technology, but not as must have. SaaS and BPaaS can be built without using server virtualization, but you can also use IaaS as the enabler for SaaS. Private Clouds, what else? The natural extension of Private Cloud computing is its expansion to include cloud services from cloud service providers. This inclusion of other services is indicated several times in previous sections. For example, you can extend your compute power with Fujitsu s Infrastructure-as-a-Service offering when you need more capacity than your Private Cloud can provide. Or you use our Backup-as-a-Service offering; originally developed to support SMBs to fulfill certain compliance regulations. The inclusion of public or community cloud offerings is the next step after having a Private Cloud on-premises implemented. Microsoft Private Cloud Fast Track This program initiated by our technology partner Microsoft describes in detail how exactly a Private Cloud infrastructure has to look to operate Microsoft applications best. Fujitsu, as one of the first five members, joined this initiative directly with its announcement in November According to the strict requirements of the program and with the claim to increase the value provided by reference architectures, we jointly defined our reference architecture with Microsoft. Fujitsu s configurations, except the special versions for SMBs, consist of Fujitsu PRIMERGY Servers, Fujitsu ETERNUS Storage, Fujitsu ServerView Suite, network components and the Microsoft management software stack. Intel Cloud Builder As opposed to Microsoft Private Cloud Fast Track, this program initiated by our technology partner Intel focuses on any kind of reference architecture to build cloud infrastructures. But Fujitsu as one key contributor focuses on reference architectures for building Private Clouds on-premises, which are all different to our contribution at Microsoft Private Cloud Fast Track. Beside that we build solutions with different Private Cloud management stacks, Fujitsu s own solution using ServerView Suite and VMware or Microsoft tools. We also integrate various elements of our cloud-optimized product offering (e.g. Fujitsu PRIMERGY BX, CX and RX described in further sections of this white paper) in our reference architectures. In cooperation with Intel we are continuously setting up new configurations for different customer needs. We use the Intel Cloud Builder Program to provide our customers with publicly available guidance including a very detailed description of how to build their Private Cloud. Page 11 of 42

12 Versatile servers with top performance FUJITSU Server PRIMERGY Rack Virtualized environments as well as Private Cloud infrastructure require a reliable and powerful IT infrastructure that supports productivity while being efficient and flexible to meet the demand of tomorrow. As the operational heart of every data center the servers should be optimized to run their workloads. Fujitsu PRIMERGY rack servers deliver the flexibility and scalability to achieve this while also lowering costs and improving productivity. In fact, Fujitsu PRIMERGY rack servers are the first servers to use 1 Watt or less per transaction, while competitive products consume five times more power. Combined with best-in-class price/performance results this contributes to favorable lifecycle costs. They are also integrated into the Fujitsu ServerView suite (own section of this white paper), which enables efficient, intelligent management that simplifies administration and improves responsiveness to quickly adopt new business changes. Finally, the Fujitsu supply chain provides the customization required to deliver a tailor-made, tested and preassembled configuration to your site. A high-quality IT infrastructure is the foundation of the productivity and continuity that are essential for the success of any business. That s why Fujitsu is so focused on quality assurance and engineering. It ensures the high availability of our rack servers, associated with tailor-made maintenance services to support stringent SLA requirements. This results in extremely low annual failure rates which are comparable to those of UNIX servers, and protect your investment over the product lifecycle. IT performance is another key element for business success. Fujitsu PRIMERGY rack servers achieve world records and best-in-class results in different disciplines: Nearly all Fujitsu PRIMERGY rack servers lead Intel-based server rankings in CPU and Java performance benchmark results. This is also reflected in VMware virtualization environments, where Fujitsu PRIMERGY rack servers have achieved leading performance positions. To stay competitive, reducing costs is essential for all companies. Fujitsu PRIMERGY rack servers contribute to this goal by delivering efficient servers and management tools to increase business productivity, while simultaneously reducing operational costs through energy efficiency that is up to 20% better than competitive products, virtualization and simplified management. Fujitsu PRIMERGY rack servers lead the market in energy efficiency with unique Cool-safe technology. In fact, Fujitsus Cool-safe Advanced Thermal Design enables support of environmental temperatures of up to 40 C. The temperature in a data center can thus be increased by a few degrees without any problems. Each additional degree means approx. 5-6 % less energy costs for air-conditioning.

14 Economies of scale FUJITSU Server PRIMERGY Blade The whole world today is thus connected via networks which generate a huge amount of data and almost everybody is able to access information anytime and anywhere. Thus lots of companies are placing greater emphasis on the operation of their IT environments, not only to gain a competitive advantage in the market but also because IT services and applications have become a critical element in day-to-day business and workforce productivity. Due to this increasing demand, server rooms have to host a large number of often different hardware platforms. This makes an IT environment extremely complex and difficult to manage, leading to high costs due to personnel-intensive administration on the one hand and excessively required space on the other hand. For the operation of these systems the energy required for power and cooling emerges as an increasing share of the costs compared to the pure acquisition costs. Fujitsu PRIMERGY Blade Servers are a perfect supplement for x86 server virtualization and provide additional advantages, such as improved manageability, greater availability and operational efficiency through a shared infrastructure and virtual input/output. Fujitsu PRIMERGY Blade Servers offer the ideal balance of performance with scalability, and are the standard for a wide variety of enterprise business and HPC scale-out applications for small, medium, and enterprise data centers. They are the perfect platform to build a private cloud or converged infrastructure, designed to maximize time and efforts. The blade enclosure provides all the power, cooling, and I/O infrastructure needed to support a modular infrastructure, interconnects and storage components today and throughout the next several years. PRIMERGY Blade Servers can be used to meet increasing compute performance requirements without suffering from an explosion of costs and increased administration complexity. Fujitsu offers versatile enclosures to match the unique needs of large or small IT environments. The PRIMERGY BX900 S2 is a complete dynamic server infrastructure in one single blade chassis. The blade server can be dynamically modified for various IT requirements: it reduces costs and makes IT more flexible. The PRIMERGY BX900 has space for up to 18 server blades in a 10U chassis. The Fujitsu PRIMERGY BX400 is a fully-featured blade system built from the ground up to be user-friendly and versatile, ideally suited for midmarket organizations and branch offices. It provides an optimum combination of up to eight server or storage blades in a small enclosure as a rack version with 6 height units or as a separate floor-stand version. Fujitsu PRIMERGY BX900 S2 Page 14 of 42

15 As compute nodes, Fujitsu offers two different dual-socket server blades which can be used in both chassis. The Fujitsu Server PRIMERGY BX920 S4 is equipped with the cost-optimized Intel Xeon E v2 processor product family and offers the ideal balance between performance and cost efficiency. The Fujitsu Server PRIMERGY BX924 S4 sets new standards in the area of versatility and scalability of dual-socket server blades and thus reinforces its position as a high-end server. With two CPUs of the new Intel Xeon processor E v2 product family, 24 DIMM slots supporting up to 1,536 GB of memory and an integrated 10 Gbit/s Ethernet Universal Converged Network Adapter (UCNA), the server blade is ideally suited for extensive virtualization and consolidation projects. They can be equipped with the latest Intel Xeon processor E5 product family, provide scalable memory configurations with up This UCNA enables Ethernet on its own and as a combination of Ethernet and Fibre Channel over Ethernet (FCoE) protocols and can be used to partition the 10 Gigabit Ethernet adapter into up to eight physical functions, so that the individual bandwidths of the channels can be adapted to the requirements of each application. Thus offers considerable benefits for virtualized environments. Traditional virtualized environments often require between six and eight connections per server in order to migrate virtual machines and for the management, backup and storage connections. The converged network adapter can replace traditional Host Bus Adapters and Ethernet Network Interface Cards, thus notably reducing costs. Fujitsu PRIMERGY BX400 S1 Page 15 of 42

16 Cloud extension servers FUJITSU Server PRIMERGY CX Both server virtualization and cloud computing deal with large-scale use scenarios, which will inevitably grow to encompass broader service requirements in order to map individual business dynamics. Therefore, the server infrastructure has a very important impact, especially if much computing power is needed. On the other hand, traditional data center facilities do not easily keep pace with those massive compute capacity demands, since they have to master additional challenges: The Fujitsu PRIMERGY CX Cloud extension servers are targeting large scale-out server deployments. Increased power envelopes and cooling requirements for those servers and related infrastructure Limitation in data center floor space, and the requirement for more computing power in a limited amount of space Limited budgets enforcing minimized initial purchase costs and subsequent maintenance costs and operational spending The need for more efficient manageability and less complexity in the operation of massive scale-out compute resources The Fujitsu PRIMERGY CX Cloud extension servers are Fujitsu s platform for cloud computing, high performance computing (HPC), service provider and any large scale-out computing server farm. They focus on providing large data centers with massive scaling power for x86 servers, while at the same time delivering new data center economics for server density, energy consumption, heat optimization and lower overall operational costs. The Fujitsu PRIMERGY CX server family has everything customers need to achieve a new dimension of cost-effectiveness with a cloud data center. Due to their innovative scale-out design, the Fujitsu PRIMERGY CX servers require less space per rack and less energy & heat per server as compared to conventional rack servers. They pay dividends in significantly lowered operating expenses, easier installation and more aggregated computing power in the data center at lower all around investment. Page 16 of 42

17 Fujitsu PRIMERGY CX400 S2 Scale-out smart FUJITSU Server PRIMERGY CX400 multi-node server provides a condensed form factor, enabling you to scale-out smart by packaging 4 independent dual-socket server nodes and up to 24 local storage drives into a consolidated 2U rack enclosure. Fujitsu PRIMERGY CX400 fits smartly into existing data center racks, by providing full compliance to conventional front-to-back airflow, standard 19 housing of the CX400 chassis and rear connectivity for communication. In this way, team play with an existing rack server infrastructure is easy to achieve. Its 4 in 2U granularity results in half of the rack space used, lower hardware investment and consolidated efficiency in management for the same performance as compared to standard rack servers. The result is significantly higher performance per standard 19 rack. Spend small The minimalistic design of Fujitsu PRIMERGY CX reflects the fact that scale-out applications stacks use software functions in the solutions architecture to care for failover and redundancy. This means that hardware-based redundancies can be replaced by those software functions, thus reducing the number of hardware components required with each server unit. And that in turn pays dividends streamlined CX server units, cutting down procurement costs compared with conventional rack server configurations. The space-saving design also ensures that extensions in the data center do not require additional square footage. The result is savings in the cost and work of providing the physical infrastructure. All this has a positive impact on your IT budget and your capital expenses: Depending on the configuration, you can slash these costs by up to 20% with the Fujitsu PRIMERGY CX servers, compared with traditional rack servers. Fujitsu s PRIMERGY CX400 uses shared redundant fans and power supplies. The energy consumption is significantly minimized while providing enhanced availability and higher effectiveness of management with hot-plug server nodes, power supplies and local storage drives. Cost-effectiveness is granted for Fujitsu PRIMERGY CX400 by conventional front-to-back cooling, rear-side external connectivity, installation and operation in existing data center rack and air conditioning infrastructures. The server nodes can be individually configured and independently serviced. Additionally a choice of PRIMERGY CX dual-socket server nodes with the latest Intel Xeon processor E5 family without (1U height) and with (2U height) GPGPU (General Purpose Graphics Processing Unit) and co-processor options enable great flexibility to match different solution stacks with Fujitsu s PRIMERGY CX400.

18 Integrated server lifecycle management ServerView Suite Companies today expect considerably more from their IT departments than just the safeguarding of computer operations: Irrespective of the economic situation the pressure to continue to provide services, which are equal to or even better than the previous ones, is on the increase while budgets are frequently stagnating. To ensure that this task does not become insurmountable Fujitsu has been continuously revising system management functionality in order to meet these increased demands. The focus is traditionally on those functions, which ensure fail-safe and flexible operation of servers in addition to the constant availability of business-critical data and which also facilitate their consolidation. Our key attention was recently placed on integrating technologies for the virtualization, dynamization and automation of IT landscapes up to their integration in cross-location and corporation solution concepts, e.g. cloud computing. ServerView Suite is the management tool from Fujitsu used for the administration of industry-standard servers. Its focus is traditionally on those functions, which ensure fail-safe and flexible operation of servers in addition to the constant availability of business-critical data and which also facilitate their consolidation. Fujitsu s ServerView Suite offers comprehensive administration covering the overall lifecycle of individual computers as well as entire machine parks and which combines decisive cost benefits with maximum performance and user-friendliness. Although existing IT capacities are better used thanks to virtualization and a medium to long-term reduction can even be achieved with them, administrative spending grows compared to conventional infrastructures with their clear-cut allocation of servers and applications. Therefore, companies need a management platform, which combines a consistent view of the IT landscape with comprehensive functions that are centrally managed from a single point of control. Fujitsu ServerView Suite is one such platform which is also easy to understand and operate. Functionally, it is divided into the five subsections: Deploy, Control, Dynamize, Maintain and Integrate. It is designed for use in so-called Open Systems environments, i.e. on industry-standard servers which run under the operating systems Windows and Linux (SuSE and Red Hat) or are used as hosts for VMs that use a hypervisor like VMware ESXi, Citrix XenServer or Microsoft Hyper-V. Standardized administration of physical and virtual servers As one of the core components in the subsection Control Fujitsu s ServerView Operations Manager (SV OM) supports the standardized administration of all physical and virtual servers in the network. This enables control in just a few steps and at the same time ensures increased system availability. A well arranged management console that gives administrators a clear overview of the states of physical servers, VM hosts and virtual machines. It can be used to perform all the important basic operations (starting/stopping, interrupting/resuming and restarting servers). Furthermore, it shows all the configuration parameters in full, thus creating at the same time the basis for detailed performance monitoring and coherent event management. The subsection Dynamize combines a series of special system management tools, which above all permit dynamic and efficient use of physical and virtual resources. They differ from the prevalent tools in SV OM by the fact that they also have comprehensive functions for the automated provision and administration of IT infrastructure resources. This includes the following products: Fujitsu ServerView Virtual-IO Manager (SV VIOM) Fujitsu ServerView Resource Orchestrator Virtual Edition (ROR VE) Fujitsu ServerView Resource Orchestrator Cloud Edition (ROR CE) Efficient Virtual-IO Management The aim of Fujitsu ServerView Virtual-IO Manager (SV VIOM) is to ensure as smooth and efficient as possible communication of the PRIMERGY blade and rack server with clients and storage arrays. For this purpose the module allocates previously defined virtual network addresses to the individual servers and also determines via which interfaces they are to establish connection to the LAN or SAN and how they are to be booted. To enable this to work the SV VIOM saves all the specific information about the computers (e.g. MAC addresses and WWNs) in a separate, hardwareindependent server profile, which is kept in a central repository outside the server. Page 18 of 42

19 As a result, individual applications can be started without any further configuration effort by the administrator allocating a specific profile to a server and by using the address previously defined for this purpose. Ultimately, the SV VIOM creates a separate domain for server management, thus separating it completely from LAN or SAN management. Any conflicts and overlapping between server, LAN and storage management are ruled out from now on, because through using constant virtual addresses there are no changes in LAN and SAN management. Automating server lifecycle operations Fujitsu ServerView Resource Orchestrator Virtual Edition (ROR VE) is a system management tool that delivers integrated administration of physical and virtual servers. By simplifying and automating server lifecycle operations across both physical and virtual environments, IT organizations can increase the efficiency of their day-to-day server operations. Time for deploying or exchanging servers can be reduced by up to 90%. Moreover, ROR VE enables cost-efficient N+1 high availability. IT organizations can now protect more servers without paying a premium for dedicated high-availability tools like cluster software. By assigning one or more spare servers to a pool of production servers, it is possible to automatically failover any production servers to the spare server in the event of hardware or operating system failures. Business applications can be resumed without any administrator intervention. Compared to manual recovery processes, server recovery time is reduced significantly, thus resulting in faster responses to server failures. This applies to both physical and virtual server environments. Build your Private Cloud infrastructure ServerView Resource Orchestrator Cloud Edition (ROR CE) delivers all the functions needed to manage a private cloud infrastructure. The software is specifically designed to set up an Infrastructure as a Service (IaaS) environment with shared resource usage. ROR CE delivers dynamic resource management and cloud service management enabling self-service provisioning for simple and speedy IT delivery. Physical and virtual servers independent of the hypervisor or a mix thereof (e.g. VMware vsphere, Microsoft Hyper-V, RedHat KVM or Oracle VM) are supported storage and networks, are automatically provisioned in minutes, at a fraction of the cost of traditional provisioning methods. In addition, ROR CE guarantees the availability of IT infrastructures by providing a number of high-availability options at various levels. From the protection of single physical and virtual servers, to recovery support for a complete blade chassis or storage system failure, to disaster recovery in the case of complete site failures. Ready for self-service provisioning ROR CE fundamentally changes the way IT resources are provisioned and the way IT users get access to these resources. IT users are provided with a service catalog of predefined infrastructure templates which include logical descriptions of single virtual or physical servers, plus multi-server configurations. Available on a web portal, this service catalog enables IT users to easily select and request their IT resources. Consider a sample usage scenario where an IT administrator requires IT resources for a web service. Instead of directly approaching the IT department, he just opens the service catalog on the self-service portal, selects a multi-server platform and starts the provisioning request. Upon approval of his request, the complete provisioning process runs unattended without any administrative intervention. ROR CE takes the required resources from the resource pools and automatically builds a ready- to-use multi-server configuration consisting of virtual and physical servers, storage and network connectivity. Constantly optimize infrastructure In addition, the self-service portal allows access to advanced system management capabilities providing tools for central monitoring of IT resources, optimizing and planning resource pool capacity, and for gaining access to accounting information. Automatic build Resource request Admin approval Infrastructure ready to use Page 19 of 42

20 The Flexible Data Safe FUJITSU Storage ETERNUS DX Data has been growing at an annual rate of about 60% for years and is increasing at the same rate. The demand for virtualization, for server consolidation and cloud computing is rapidly increasing. This is why many storage administrators are familiar with the problem of overload caused by the continual rapid growth in data volume. New applications and an increasing amount of non-struc- tured information and data analyses mean that many IT systems have reached their capacity limits. The I/O requirements of today s applications have also become more demanding The market will require storage and servers to have higher performance, higher reliability, greater functionality, and increased cost effectiveness. Many already described key functions like Live Migration, High Availability, Dynamic Resource Scheduling or Disaster Recovery mechanisms, just to name some, cannot happen without a central storage system, which is the center piece of any virtual machine farm and Private Cloud infrastructure. Fujitsu has redefined the standards of enterprise storage with the introduction of the latest generation of Fujitsu ETERNUS DX systems in Combining leading performance architecture with automated quality of service management the ETERNUS DX series aligns storage resources with business priorities, thus enabling higher system utilization and delivering increased system consolidation capabilities and a faster ROI. Unified scalable entry-level and midrange systems, a seamless family concept enabling system upgrades and ETERNUS SF, the unified management suite across the product line, reduce operational and migration costs. ETERNUS SF provides enterprise-class functionalities in the entry and midrange class and allows flexible disaster recovery concepts for the different model sizes, thus decreasing investment costs. Whereas traditional vendors offer different and discrete storage architectures in the entry-level, midrange and high-end segment, the ETERNUS DX approach differs with one uniform system design and uniform system management over the complete product line in all system segments. The only model-specific component is the storage control unit; all other components like disk shelves and management software products are the same for all models. This allows upgrading of smaller systems into larger ones by just exchanging the control unit. Administrators who know how to operate one ETERNUS DX model can run any other model in the same fashion. Customers and partners benefit from this architectural principle through less costs of growth and reduced operational effort. ETERNUS DX a central piece of virtualized and cloud data centers Storage operations, especially in highly virtualized environments, generate a huge workload in data center administration. This is where Fujitsu ETERNUS SF management software helps with its standardized storage management. If you know how to operate one storage device in the family, you are able to run any of them! Innovative advanced functions help to increase operational efficiency. For example, Thin Provisioning means that the administrator can assign virtual capacity to applications so that the real, existing capacity can be pooled. There is no need to invest up front in disk capacity, which is just reserved for future demands in specific cases and is not used productively in the short term. Fujitsu ETERNUS SF management software also offers close integration with server virtualization offerings, such as VMware. It enables storage systems and servers to work together with onsite failovers during disasters, and it enables servers to offload tasks to the storage system, for example provisioning, cloning or the replication of virtual machines.
