With sophisticated, built-in reliability, availability and serviceability (RAS) features, it reduces the risk of unplanned downtime for mission-critical applications. CB 500 is one of the most flexible systems on the market today. This white paper provides a high-level overview of the key features and capabilities that make Hitachi Compute Blade 500 a preferred choice over any other blade or rack server platform on the market today. And it shows how CB 500 delivers new opportunities for companies of all types and sizes.

4 WHITE PAPER 4 Introduction to Hitachi Compute Blade 500 Hitachi Compute Blade 500 is an enterprise-class blade server platform that extends high-performance, high-density blade computing and virtualization benefits to new areas of the data center (see Figure 1). This section describes how CB 500 overcomes the constraints of previous-generation blade systems to deliver new capabilities and opportunities in an enterprise. Subsequent sections provide additional details about key features and functionality. System Overview Hitachi Compute Blade 500 with logical partitioning (LPAR) combines all the benefits of virtualization with all the advantages of the blade server format: simplicity, flexibility, high compute density and power efficiency. This combination allows organizations to consolidate more resources, extend the benefits of virtualization solutions (VMware, Microsoft Hyper-V and so forth) to more areas of the enterprise data center, and cut costs without sacrificing performance. Figure 1. Powered by Intel Xeon E5v3 and E7v3 series processors, Hitachi Compute Blade 500 packs up to 288 cores into a fully loaded system. By powering the system's blade modules with Intel Xeon E5v3 and E7v3 series processors and radically increasing the I/O performance and memory capacity, Hitachi has made it possible to use virtualization to consolidate application and database servers. These are areas where effective consolidation was difficult in the past. By removing performance and I/O bottlenecks, CB 500 with logical partitioning reduces the administrative burden in the data center and opens up new opportunities for increasing efficiency and utilization rates. Optional mezzanine I/O cards connect to the shared midplane of CB 500 to allow each blade to access common redundant shared network switches. This capability simplifies connection, saves money and eases administration. To enable I/O versatility, CB 500 supports two pairs of redundant bays for internal switches, which can support IP networking (1Gb or 10Gb Ethernet), Fibre Channel or converged fabric I/O. Built-in logical partitioning is a key feature of Hitachi Compute Blade 500. Hitachi logical partitioning is the industry's first embedded hardware-based and hardware-assisted virtualization solution, based on proven, mainframe-class technology. There is no complex installation process: It just runs, right out of the box. Unlike emulation solutions, it

5 WHITE PAPER 5 doesn't slow application performance down. And because no software hypervisor is required, your operating system (OS) and applications don't require special drivers or software. The identical software stack is used in a logical partition as on a blade without logical partitioning enabled, simplifying management, and reducing costs of operation and administration. Logical partitioning complements existing software-based virtualization solutions and can be used in conjunction with VMware, Hyper-V or Red Hat KVM. You can even combine multiple virtualization platforms in a single chassis, providing the greatest virtualization flexibility in the industry. CB 500 also offers the very latest in power-saving features and capabilities. With industry-leading 94% efficiency, the power supplies have been awarded the 80 PLUS Platinum certificate and conform to the Climate Savers Computing Initiative Gold standard. CB 500 is not only powerful and efficient, but manageable and flexible, too. You can configure and administer CB 500 via a Web-based HTML browser that supports secure encrypted communications, or leverage the optional Hitachi Compute Blade management suite to manage multiple chassis via a unified graphical user interface (GUI) based interface. You can deploy CB 500 at the edge, application or database tiers, or all three at the same time. You don't need to choose between Microsoft Windows or Linux: You can run both in the same chassis. And CB 500 integrates effortlessly into your network I/O infrastructure thanks to its adaptable and highly expandable I/O architecture. Enterprise-Class Capabilities Hitachi Compute Blade 500 is a true enterprise-class blade server, and it is important to understand exactly what that term means. It is "enterprise-class" in terms of performance, scalability, reliability and configuration flexibility, as outlined below: Performance. CB 500 supports blades based on the latest and most powerful Intel Xeon E5v3 and E7v3 series processors with up to eight CPUs per blade (in SMP mode). It meets the performance needs of large-scale systems that require extremely high compute power and I/O today. The extensible CB 500 architecture can support multiple blade types, including future generations of Intel processor. Standard-width CB 500 blades can also be expanded to support additional high-density disk (HDD) storage or additional PCI slots with an expansion blade installed in an adjacent blade slot. Scalability. The robust, rack-mountable 6U chassis of CB 500 houses up to eight server blade modules; each standard-width blade may have up to two sockets, with up to 18 cores per socket. Double-width blades can support up to two E7 processors with up to 15 cores per socket. Each blade may be configured to support up to 30 logical partitions. Memory is expandable up to 48 DIMMs in the CB520X blade, allowing up to 1,536GB to be configured per blade using 32GB DIMMs. Each standard-width blade supports up to two I/O mezzanine cards to connect to the chassis (four in the double-width blade), allowing each standard blade to support up to four I/Oswitch modules (usually configured as two redundant pairs). Reliability. CB 500 chassis is fully redundant and components are hot-swappable. These components include: redundant switch and management modules, extremely reliable backplane and I/O, N +1 or fully redundant power supply modules, and N+M blade failover protection (referring to "M" backup blades for every "N" active server blades, so failover is cascading). In the event of blade hardware failure, the system automatically detects the fault and identifies the problem by indicating the faulty module, allowing immediate failure recovery. In addition, the CB520Hv3 blade takes advantage of the latest high availability features built into the Intel Xeon processor, such as memory mirroring and rank sparing. Configuration flexibility. CB 500 supports Windows and/or Linux OSs, and a wide range of virtualization solutions, including native LPAR, providing a high level of flexibility and investment protection. The system can easily be configured to the exact number of sockets, processor cores, I/O slots, memory and other components required

6 WHITE PAPER 6 to optimally support your application without bottlenecks. The chassis can be configured and managed via simple GUI HTML-based Web interface, which is seamlessly integrated with the Hitachi Command Suite tools used to manage Hitachi storage products. Workload flexibility. The enterprise-class capabilities of CB 500 make it suitable for a wide variety of applications. CB 500 allows you to run your most demanding workloads, whether they are I/O-intensive applications such as online transaction processing and Web serving, or high-performance computing (HPC), with extremely high performance, reliability, manageability, scalability and flexibility. Because of this extreme flexibility, CB 500 is the ideal platform to run mission-critical applications and consolidate systems at the edge, application or database tiers... or all three. Data Center Applications Hitachi Compute Blade 500 can be deployed in an array of data center scenarios, including those aimed towards: Consolidation. CB 500 is an excellent platform for server and application consolidation because it can run 32-bit and 64-bit applications on Windows or Linux, with enterprise-class performance, reliability and scalability. Workload Optimization. CB 500 runs a wide range of compute-intensive workloads on either Windows or Linux, or both. This approach makes it possible to balance the overall data center workload quickly and without disruption or downtime. Resource Optimization. CB 500 enables the IT organization to increase utilization rates for expensive resources, such as processing power, making it possible to fine-tune capacity planning, and delay or eliminate unnecessary hardware purchases. Cost Cutting, Risk and Complexity. With CB 500, acquisition costs are lower than traditional UNIX servers or rack-mount servers. You can scale up on demand in fine-grained increments, avoiding capital expenditures. CB 500 also reduces the risk of downtime because sophisticated RAS features are built in. And with support for industry standards, future Intel Xeon processors, and potential new blade options, CB 500 decreases the risk of technology obsolescence and protects previous investments. Balanced, Modular Architecture Hitachi Compute Blade 500 features a very modular design to maximize flexibility (see Figure 2). All core system elements are redundant and hot-swappable, so the system can be easily expanded without downtime or unnecessary disruption to service levels.

7 WHITE PAPER 7 Figure 2. All Hitachi Compute Blade 500 modules are redundant and hot-swappable, providing high reliability and uptime. Chassis Design With a 6U chassis that is 19-inch rack compatible, Hitachi Compute Blade 500 accommodates up to eight server modules or blades, which are populated with the latest Intel Xeon E5 series processors (see Figure 3). Each standard-width Intel Xeon E5 series processor-based module supports up to two processors and up to 18 cores per socket, for a capacity of up to 288 cores per chassis. Figure 3. Hitachi Compute Blade 500 chassis layout allows for 19-inch rack compatibility: front (left) and rear (right).

8 WHITE PAPER 8 Standard Server Blades The Hitachi Compute Blade 500 accommodates a total of up to eight dual-socket-based server modules (see Figure 4). The CB520Hv3 blades support the Intel Xeon processor E5-2600v3 series processors with 24 high-performance DDR4 memory slots, two I/O expansion mezzanine card options and two front-accessible hot-swap hard drive bays. All models support two serial-attached SCSI (SAS) hard disk drives or solid-state drives (SSDs) with onboard RAID protection and super-capacitor-based backup. Onboard high-speed Ethernet ports are also provided. The ports can be connected to the backplane via a low-cost pass-through module. Lights-out management via HTML Web interface supports IP-based capabilities for remote access, virtual media support and front-side USB ports for direct access to the blade. Figure 4. Hitachi Compute Blade 500 employs the CB520H v3 server module. CB520X SMP Blade Unique among x86-based servers, the CB520X Hitachi Compute Blades can be connected together to grow blade capacity from two to eight sockets (configured as a single high-capacity blade) simply by adding and linking additional blades (see Figure 5). Figure 5. Hitachi Compute Blade: CB520X The CB520X blades are full width and each contains two Intel Xeon E7v3 series processors with 48 DIMM slots, two HDD bays and up to four optional mezzanine slots. The CB520X blades feature a front-side connector, which can be used to connect either two or four blades to create a single four- or eight-socket blade system (see Figure 6).

9 WHITE PAPER 9 Figure 6. Hitachi Compute Blade CB520X allows incremental expansion from two- to eight-socket blade configurations. With support for the Microsoft Windows OS and Red Hat Linux, Hitachi Compute Blade 500 gives you the option of running two of the most popular OSs at the same time and in the same chassis for multiple applications. Or, you can run them (using Hitachi LPAR) on the same blade. For example, in a virtualized environment on a single active server module, you can allocate 50% of CPU resources to Windows and 50% to Linux applications. And you can change the allocation dynamically as workload requirements shift. This provides flexibility for accommodating spikes in demand for specific application services. In addition, the system can be configured to dynamically reassign unused CPU resources from one partition to other partitions where CPU resources are under stress, and back again on demand. Storage Expansion Blade Standard-width compute blades can be expanded to accommodate up to six additional hard drives or SSDs by the addition of the storage expansion blade (see Figure 7). Figure 7. Hitachi Compute Blade server's CB520H blade capability may be extended with a storage expansion blade.

10 WHITE PAPER 10 The storage expansion blade occupies the slot adjacent to its host compute blade, effectively creating a combined double-wide blade. Up to six 900GB SAS drives may be accommodated, in addition to the two drive bays built into the CB520H compute blades. An external SAS connector is also provided. PCIe Expansion Blade Standard-width compute blades can be expanded to accommodate up to six additional hard drives or SSDs by the addition of the PCIe expansion blade (see Figure 8). Figure 8. Hitachi Compute Blade server's CB520H blade capability may be extended with a PCIe expansion blade. The PCIe expansion blade occupies the slot adjacent to its host compute blade, effectively creating a combined double-wide blade. Flexible I/O Hitachi Compute Blade 500 server modules have the ability to support a variety of switch modules and configurations. Each blade can access a common, unified, shared-switch network across all the blades while also supporting unique I/O interfaces. This capability allows you to simplify the switch interface management and physical wiring. I/O switch options include IP networking, Fibre Channel and converged data center bridged networking. These simplify the data center wiring further and allow SAN and NAS to share the same network. This capability is particularly useful if you have separate server, storage and network organizations, allowing storage resources to be managed outside of the box. Mezzanine Cards For additional I/O versatility, Hitachi Compute Blade 500 provides two slots for optional mezzanine I/O expansion cards (see Figure 9). The server allows plenty of bandwidth for the most demanding I/O-intensive applications, such as online transaction processing, high-performance computing, simulations and modeling, or batch jobs with heavy transactional loads. (When both mezzanine slots are occupied, the onboard LAN is disabled.)

11 WHITE PAPER 11 Figure 9. Hitachi Compute Blade 500 architecture provides I/O versatility. Mezzanine cards supported include: Quad-port gigabit Ethernet mezzanine option cards, allowing a total of eight GbE NIC ports per blade. Eight-port gigabit Ethernet mezzanine option cards, allowing a total of 16 GbE NIC ports per blade. Quad-port 10GbE mezzanine option cards, allowing a total of eight 10GigE NIC ports per blade. Dual-port 8GbE Fibre Channel mezzanine option cards, allowing a total of four 8GB Fibre Channel NIC ports per blade. Quad-port 8Gb Fibre Channel mezzanine option cards, allowing a total of eight 8GB Fibre Channel NIC ports per blade. Quad-port 10Gb Converged Network Adapter (CNA) mezzanine option cards, allowing a total of eight 10GB CNA NIC ports per blade. L3 Gigabit Ethernet Switch Hitachi Compute Blade embedded gigabit Ethernet switch is a managed, standards-based, layer-3 switch that provides gigabit networking required in today's enterprise data centers. The switch provides 12 (single) or 24 (redundant) 10/100/1000Mb/sec ports for connecting CB 500 server modules to other networked resources within the corporate networking structure. The switch provides up to 24Gb/sec total throughput performance and the ability to relay packets at 1,488,000 packets per second. In addition, a 1:10GbE switch module is also available for 10GbE uplink capabilities. Hitachi Compute Blade embedded gigabit Ethernet switch can be configured for high availability and fault tolerance when a second redundant switch module is added. A single switch interconnects one (of two) gigabit Ethernet connection from each blade server module (up to eight total).

12 WHITE PAPER 12 10GbE Data Center Bridging (DCB) Switch Module The CB GbE DCB switch is a state-of-the-art 10Gb embedded switch with 16 internal ports and eight external ports with wire-speed throughput and nonblocking cut-through architecture, providing industry-leading performance and ultra-low latency. It enables CB 500 to support flexible connectivity options for cloud architectures, including lossless Ethernet fabrics. The switch provides CB 500 administrators with the ability to enhance their hierarchical network architectures, deploy flatter scale-out fabrics, or converge networks when deploying virtualization and cloud IT infrastructures. Its rich set of layer 2 features can be deployed into classic 1Gb and 10Gb architectures, preserving existing network designs and cabling. Dual-speed (1Gb/sec or 10Gb/sec) capable external ports are well suited for data centers that are migrating to nextgeneration 10Gb/sec high-performance architectures and are supported by both 1Gb/sec RJ-45 connectors and 10Gb/sec twinax copper or optical connectors for ultimate flexibility. Data center bridging and multihop Fibre Channel over Ethernet (FCoE) capabilities enable lossless unified storage connectivity, and convergence of storage and LAN traffic to reduce connectivity costs. Its automatic migration of port profiles (AMPP) feature simplifies virtualized server management by enabling seamless virtual machine (VM) mobility, further simplifying management and reducing operational costs. Naturally, the DCB switch is integrated with Hitachi chassis management software, enabling end-to-end management of CB 500. Eco-Efficient Power and Cooling Hitachi Compute Blade 500 accommodates up to four power supplies in the chassis and can be configured with mirrored power supplies (or N+1 power supplies), providing backup on each side of the chassis and higher total reliability. Cooling is provided by efficient, variable-speed, redundant fan modules. Each fan module includes three fans to tolerate fan failures within a module; an entire module can fail while the other fan modules will continue to support the cooling requirements of the chassis. CB 500 also features the power-capping function, which optimizes the power consumption from server blades by controlling the frequency (CPU steps) according to processor service rate. This function saves approximately 16% of power consumption by server blades. In addition, CB 500 can provide real-time monitoring and historical data of power consumption in the server chassis. The visualized information helps reduce equipment costs, enabling facility planning for equipment installation and expansion. Hitachi Compute Blade Management Hitachi Compute Blade 500 supports up to two management modules for redundancy. Each module is hotswappable and supports live firmware updates without the need for shutting down the blades. This makes it your best choice if you are looking for a highly available system. Each module supports an independent management LAN interface from the data network for remote and secure management of the chassis and all blades. Each module supports a serial CLI and a Web interface. The management modules also support SNMP and alert notification so that administrators are always notified of any issues. HTML-Based Web Interface Basic chassis and blade operations are managed via Hitachi Compute Systems Manager (HCSM), a secure HTML Web interface that allows seamless integration with Hitachi Command Suite, simplifying management of converged

13 WHITE PAPER 13 solutions with Hitachi storage (see Figure 10). This graphical interface simplifies system configuration and supports secure and encrypted communications, ensuring that only authorized users can access resources and only authorized resources can be accessed. Figure 10. Hitachi Compute Systems Manager provides an HTML-based Web interface. KVM (keyboard-video-mouse) remote management of the blades is supported via IP with either a client-based interface, which can be installed onto a remote computer, or via the Java-based Web interface, which is accessible from any standard Web browser. The tools also support power control as well as virtual media capabilities, allowing local drives to be connected directly to the server. Logical Partitioning Embedded Virtualization Technology Logical partitioning sets a new standard for server consolidation and on-demand infrastructure provisioning. As the industry's first hardware-embedded virtualization technology for blade computing, LPAR delivers new capabilities that other popular virtualization solutions do not provide. At the same time, LPAR works well in conjunction with VMware and Microsoft Hyper-V within a single system to increase configuration flexibility. Overview and Key Benefits Virtualization allows you to treat your CB 500 as a pool of resources so you can allocate processing power on demand, improve utilization rates, and delay or avoid purchases of new systems by partitioning a single server environment. Virtualization is also useful for server consolidation, which delivers simplified administration, a smaller footprint per server, improved security and other advantages. Logical partitioning delivers high performance, extreme reliability, security and transparent virtualization for the Intel Xeon processor E5 series server modules on Hitachi Compute Blade 500. It supports numerous guest OSs, including

14 WHITE PAPER 14 Red Hat Linux and Windows, and it does not intrude at the OS level, thus maximizing security, performance and simplicity. It keeps the data center agile and responsive to fast-changing business requirements. Whether the environment is running on a bare-metal server or on LPAR, there is no need for additional drivers or changes to applications. Because logical partitioning is built into the blade firmware, there is no installation and setup required, reducing total acquisition costs and simplifying the move to a partitioned environment. You can activate logical partitioning or deactivate it quickly and easily via the management console. Logical partitioning allows you to create multiple independent logical partitions (LPARs), which run on specific hardware resources uniquely allocated to that partition by the administrator. Each logical partition appears to its operating system to be an independent physical server. CB 500 offers two deployment models for logical partitioning: The "Essential" model is included with each system and allows you to create two LPARs per blade at no additional cost. The "Enterprise" model requires an additional license and allows the creation of up to 30 LPARs per blade on CB 500. Logical partitioning is firmware based and thus has a natural performance advantage over host-emulation virtualization offerings, since guest OSs can be directly executed without host intervention. Logical partitioning leverages Intel Virtualization Technology (VT) to ensure that processor performance is optimized for the virtual environment. Equally important, this technology utilizes a standard filesystem (NTFS, the standard filesystem of modern Microsoft Windows OSs) and standard OS drivers, simplifying the administrator's job significantly. With logical partitioning there is no need for exclusive and costly file management, migration and/or backup tools for virtualization platforms. Logical partitioning is fast to install, configure and deploy since all virtualization files are stored in the firmware and there is no need to install or upgrade each blade with virtualization software. It also means better performance because less overhead is required for filesystem format conversions or driver emulations to consume precious CPU cycles. Drivers required are the same for either standard or partitioned environments, adding to management simplicity. Performance and Security Features Based on many years of Hitachi experience developing virtualization technology for the mainframe world, logical partitioning brings true enterprise-class performance and security to virtualization in a blade-computing environment. This technology can partition physical server resources by constructing multiple LPARs, which are physically separated, with each environment running independently. A different operating system can run on each logical partition within a single physical server. Logical partitioning also inherits the concept of "direct execution" from the mainframe world. This means that userlevel application code and OS requests are directly executed on the processor, increasing performance. Moreover, Hitachi LPAR technology has been tuned specifically for Hitachi Compute Blade 500 and has been extensively tested in enterprise production environments. To increase security, each logical partition has dedicated physical memory and cannot access the memory of other partitions. This ensures that no unauthorized access to a given device or memory is possible. Files are stored in their native formats and assigned to a separate storage logical unit (LUN). Each can be assigned with different security settings. This is a more secure approach than that used in some solutions, which employ a single file to contain all virtual machine data. Unlike software-based virtualization solutions, a separate management interface for LPAR is built into the hardware. This interface resides on a different physical network than OS traffic, ensuring that user data is completely and isolated from any management traffic, and adds yet another dimension of protection and security.

15 WHITE PAPER 15 Hitachi Compute Systems Manager Hitachi Compute Systems Manager is a standalone set of optional management tools designed for data center management of multiple chassis via a graphical intuitive interface that provides point-and-click simplicity. At the system level, HCSM provides centralized management and monitoring of extended systems containing multiple chassis and racks. Unified Dashboard HCSM allows the various CB 500 system components to be managed through a unified interface, which is seamlessly integrated with Hitachi Command Suite (see Figure 11). When rack management is used, an overview of all Hitachi Compute Blade racks, including which servers, storage and network devices are installed, can be quickly and easily obtained. In the event of any system malfunction, the faulty part can be located at a glance. In addition, HCSM software provides the ability to define and manage the logical system configuration of each element to be managed by using the service name. With traditional blade servers, management of both the logical system and the system's physical resources is required. When definitions are made with service names (such as sales or stock) within Hitachi Compute Blade management suite, there is no longer any need for administrators to concern themselves with the management of physical resources. HCSM provides centralized system management and control of all server, network and storage resources. This includes the ability to set up and configure servers, monitor server resources, integrate with enterprise management software (SNMP), phone home and manage server assets. Optional plug-in modules are available to extend HCSM capabilities: Deployment Manager. Performance Gauge. N+M Cold Standby. Logical Partitioning Manager. Power Conductor. Efficiency Pack.

16 WHITE PAPER 16 Figure 11. Hitachi Compute Systems Manager offers a unified view of platform management. Deployment Manager Deployment manager allows the mass deployment of system images, patches and hot-fix updates for fast, effective server installation and patch management. You can deploy system images and updates across multiple chassis in multiple locations. In addition, Hitachi also offers backup capabilities with the deployment feature. N+1 or N+M Cold Standby Failover Hitachi Compute Blade maintains high uptime levels through sophisticated failover mechanisms. The N+1 cold standby function enables multiple servers to share a standby server, increasing system availability while decreasing the need for multiple standby servers or costly software-based high-availability servers. It enables the system to detect a fault in a server blade and switch to the standby server, manually or automatically. The hardware switching is executed even in the absence of the administrator, enabling the system to return to normal operations within a short time. With the N+M cold standby function, there are "M" backup server blades for every "N" active server blade, so failover recovery is cascading. In the event of multiple hardware failures, the system automatically detects the fault and identifies the problem by indicating the faulty server blade, allowing immediate failure recovery. This approach can reduce total downtime by enabling the application workload to be shared among the working servers.

17 WHITE PAPER 17 Active Power Management A standard feature of all CB 500 blades is the ability to manage, or limit, the power consumed by each blade. This feature is managed at either the chassis or rack level, using a feature of the standard HCSM management software. This feature allows a power consumption ceiling to be specified. The ceiling may be lower than the theoretical maximum power consumption of a maximally configured chassis, which would normally dictate power and cooling provisioning. Data center designers can thus safely provision to a lower power and cooling load and benefit from the ensuing cost savings. Power Capacity Expansion Feature When redundant power is configured in a blade chassis, competitors place restrictions on the combination of blades, processors or memory that may be used. These restrictions ensure that in the event of a power supply unit failure, the remaining power supply capacity is not exceeded. However, the restrictions also limit the maximum compute density that can be supported. End users may assume that they have more capacity than can actually be supported. The Hitachi power capacity expansion feature removes this limit and allows the CB 500 system to be safely configured to its theoretical maximum limit (see Figure 12). The configuration includes power supply redundancy and delivers the maximum real density available. Maximum real density is achieved by responding to a failure event within milliseconds to limit chassis power consumption to the remaining available power. In normal use, power from the reserve supplies allows maximum performance of all configured blades. Figure 12. Power capacity expansion feature allows maximum density blade configurations to be supported with redundant power.
