1 TECHNICAL BRIEF Optimizing Server Management Sponsored by: HP Jed Scaramella August 2010 Summary Global Headquarters: 5 Speen Street Framingham, MA USA P F HP Insight Software is integrated management software to manage infrastructures including HP ProLiant, HP Integrity, and HP BladeSystem. A core element of the HP Converged Infrastructure and Matrix Operating Environment, HP Insight Software is designed to provide customers with deeper insight into their systems to make more informed decisions, precise control to accomplish more in less time, and ongoing optimization to deliver better services. The HP Insight Software portfolio includes HP Insight Control and HP Insight Dynamics, which play a central role in reducing overall data center operating expenses and differentiating HP offerings from competitive offerings. The core value proposition for HP Insight Control covers five primary areas: Deploy. With tools to automate deployment and migration of physical and virtual servers, HP Insight Control allows servers to be deployed quickly and with less risk than using manual processes. Manage. Incorporating HP Systems Insight Manager (SIM) and HP Insight Remote Support software, HP Insight Control enables administrators to proactively manage the health of their systems. IDC research with HP Insight Control customers conducted in June 2010 found that using these products yielded greater than 80% reduction in hardware downtime hours per month. Optimize. Companies can increase data center capacity and reduce their power bill through improved power management features. Dynamic Power Capping, Data Center Power Control, and Intelligent Power Discovery enable power optimization at both a data center level and a server level. Control. With Integrated Lights-Out 3 Advanced (ilo 3 Advanced) functionality, HP Insight Control lets administrators manage servers remotely, enabling companies to reduce administrative burden and travel expenses. Integrate. Integrations with Microsoft System Center and VMware vcenter Server enable administrators to monitor physical and virtual servers as well as applications from a single management console. IDC recently completed an updated ROI analysis of the value of incorporating HP Insight Control and determined that over a three-year period customers achieved an average ROI of over 600% and a total economic benefit over three years of more than $73,000 per 100 users from IT staff efficiencies, infrastructure cost reductions, prevention of revenue loss, and user productivity savings.

2 Data Centers Look to Streamline Management Complexity and Reduce TCO Enterprises report to IDC that IT management and administration costs have grown to eclipse all other cost categories. Driven by an explosion in the installed base of servers (see Figure 1), the personnel cost required to manage and maintain servers has put a strain on the majority of businesses' data center IT budgets. As a result, IT budgets are coming under closer scrutiny, with an eye toward identifying solutions that can demonstrably reduce costs by simplifying IT infrastructures and automating management processes. FIGURE 1 Worldwide IT Spending on Servers, Power and Cooling, and Management/Administration, Customer Spending ($B) Installed Servers (M) $300 $250 $200 $150 $100 $50 Physical Server Installed Base (M) Logical Server Installed Base (M) Power & Cooling Expense Management Cost Server Spending $0 '96 '97 '98 '99 '00 '01 '02 '03 '04 '05 '06 '07 '08 '09 '10 '11 '12 '13 0 Source: IDC, 2010 As Figure 1 shows, customers have been able to maintain a relatively flat level of capital expenditures on new servers. This has been accomplished through customers shifting their infrastructure to lower-priced standards-based x86 servers and away from high-priced mainframe and Unix server systems. The transition has controlled spending on server hardware but has resulted in a significant increase in the numbers of systems deployed in customer environments. This has caused management and, to a certain extent, power and cooling to become the biggest cost factor for server systems. Virtualization, introduced to the x86 market in the middle of the decade, has helped customers consolidate their physical servers and control the 2 # IDC

3 server "sprawl" within their environments. Yet, at the same time, virtualization is presenting new management challenges. As shown in Figure 1, IDC data indicates that the number of virtual machine deployments is rapidly climbing and is expected to exceed to the total number of physical servers in five years. "Virtual sprawl" is replacing "physical sprawl," proving the need for management solutions that have control and automation capabilities for both virtual and physical systems. In addition, server sprawl has led to a number of other problems for today's IT organizations: Inflexibility. As currently deployed by most organizations, server configurations are static, hardwired, and difficult to change. Manual coordination. Maintaining and changing applications or server configuration require too many people to perform too many manual steps. Underutilization. With 1:1 application-to-server deployment ratios, only a fraction of most servers' total capacity is typically utilized. Overprovisioning. Hand in hand with underutilization, overprovisioning results in wasted rack space, power, cooling, bandwidth, and operational costs. Unique management requirements. Many processes and applications supported by servers are unique, requiring IT organizations to maintain individual tools and coordinate inconsistent configurations to handle them all. In sum, server infrastructures can often consume large amounts of space, power, and IT administration time. The costs associated with deploying, monitoring, and managing servers have escalated to the point where IT organizations are actively seeking tools to help them manage costs by streamlining management and automating key server management tasks throughout the data center. HP Insight Control Part of the HP Insight Software portfolio, HP Insight Control is an integrated software suite that allows customers to continuously manage, control, and optimize their infrastructure across a variety of platforms, including HP BladeSystem and HP ProLiant. A key part of HP's overall Matrix Operating Environment which has the goal of delivering a common management platform to automate infrastructure life-cycle management and is a key component of the HP Converged Infrastructure HP Insight Control provides server deployment, health and performance management, power management, remote management, and virtual machine management for both HP environments (HP BladeSystem and HP ProLiant). The central value proposition of HP Insight Control is to improve customers' ability to deploy, manage, optimize, control, and integrate their environments (see Figure 2) IDC #

4 FIGURE 2 HP's Depiction of Key HP Insight Control Values Notes: 1. IDC research conducted with seven HP Insight Control customers and completed in June 2010 found that deployment times per server were reduced 84%. 2.. IDC research on HP Insight Control 1 found an 83% reduction in hours of downtime per month for internal users. 3.. HP Performance Engineering Team, 2008 Benchmark estimates that customers may deploy triple the number of servers per power capacity using Dynamic Power Capping. This estimate uses server faceplate values and server density improvements that may vary based on how customers budget power and cooling resources. 4. IDC research on HP Insight Control 1 found average IT staff efficiency savings of over $25,000 per year per site. Source: HP and IDC, 2010 HP Insight Control helps differentiate HP server offerings by making them simpler and more seamless to manage. By taking advantage of intelligence built into the hardware platform, they can help simplify deployment and infrastructure life-cycle management, which in turn can increase system availability, create tangible data center efficiencies, and provide administrators with greater control. Automated Deployment Features to Improve Speed and Reduce Risk HP Insight Control provides deployment tools for configuring new servers and migrating existing servers, whether they are physical or virtual. HP Insight Control server deployment facilitates the installation and deployment of new HP ProLiant and HP BladeSystem servers through an automated process that reduces deployment time and human error. HP Insight Control virtual machine management creates configuration templates that enable customers to configure systems once and deploy multiple times. 4 # IDC

5 Additionally, it allows them to do imaging, hardware, and operating system configuration from a single interface. HP estimates that an HP ProLiant server can be deployed 12 times faster using HP Insight Control than using vendor-provided CDs or DVDs. Because change is inevitable in a data center, HP Insight Control server migration provides an automated method to migrate existing workloads to new HP ProLiant or HP BladeSystem servers. HP Insight Control supports multiple virtualization environments, including VMware and Microsoft. It provides the automated ability to transfer OS, applications, settings, and stored data to save time and reduce risk. Proactive Management to Reduce Unplanned Downtime HP Insight Control includes HP Systems Insight Manager, which enables administrators to proactively monitor their infrastructure from a single console, and HP Insight Remote Support, which allows customers to provide secure remote support for servers, storage, and network environments. It allows them to keep an eye on system health, performance, workload functions, server utilization, and power usage, and they can monitor HP ProLiant and HP BladeSystem infrastructures from the same console. It also enables proactive management and response to configuration anomalies and performance issues. HP Insight Control provides central management of virtual machines with physical host to virtual machine association; identification of virtual machines or host servers reaching high CPU, memory, or disk utilization levels; flexible move capabilities that allow live moves (for some platforms) and moves to dissimilar host resources; and backup, template, and alternate host capabilities that enable restoration of virtual machines on any available host. IDC interviews with HP Insight Control customers found that by managing system health proactively, they have been able to reduce unplanned downtime by over 80% on average. Increase Data Center Capacity by Optimizing Power Management HP Insight Control is designed to help data center managers optimize power management, both to increase data center scalability and to reduce their power bill. It provides power management optimization capabilities at both the data center level and the rack level. Data Center Power Control: Optimizing Power Usage Across the Data Center Data Center Power Control is an HP Insight Control feature designed to let customers take control of the power usage throughout their data center. It lets customers define policies for critical servers and applications and allows them to keep power flowing to these critical servers even during unplanned outages or events. In addition, it can help customers lower their energy bills by driving infrastructure into a more efficient operating range and dropping power usage during peak or coincident peak times IDC #

6 Dynamic Power Capping and Intelligent Power Discovery: Power Management at the Rack Level With Dynamic Power Capping, HP Insight Control can help companies measure, manage, and reduce the amount of power required by the servers in their data center. It enables companies to identify unused or "trapped" power capacity at the rack level and to deploy servers to reclaim this capacity. Organizations can then set power caps at the individual server or HP BladeSystem enclosure level to ensure the infrastructure does not exceed the available energy budget, even at times of peak server load. HP Insight Control also provides a view of the data center, showing the layout of the rack and inlet temperatures of the servers, and the ability to see a thermal and electrical view of the rack. With Intelligent Power Discovery, HP Insight Control can manage power usage of legacy HP and non-hp servers. Intelligent Power Discovery is enabled by special cabling that automatically discovers key parameters of the server (such as the server type and size as well as IP address) and feeds the information to HP Insight Control to reduce errors in compiling system inventory information and to automate the monitoring and management of power requirements at the server and rack level. Control Systems Remotely to Reduce Administrative and Travel Expenses Now in its fifth generation, HP ilo 3 Advanced lets administrators control their servers remotely from almost anywhere. It allows administrators to take control of systems from a central location to restart servers, control power settings, update software, and interact with the operating system remotely. It provides a full graphic view of the server as well as automatic video recording and team collaboration capabilities. And because ilo 3 Advanced can be used to diagnose server problems regardless of the server's geographical location, it helps customers save on staff time and travel budgets. Enhancements to ilo 3 include improved performance of the remote console that HP benchmarks as eight times faster than that available with ilo 2, improvements to the management interface to make it easier and more intuitive to use, and enhanced standards support, particularly for security and single sign-on standards. Integrate to Extend Server Management to Other Leading Consoles HP Insight Control now incorporates deep-level integration with both Microsoft System Center and VMware vcenter. With these integrations, customers can take advantage of HP Insight Control management capabilities for their server environments using the management console they are already familiar with or have already installed, and they can perform physical and virtual server and application management from the same console. Microsoft System Center Microsoft System Center is used by many enterprises to perform monitoring and alerts at the application level, both for Microsoft products such as SQL Server, Exchange, and IIS and for third-party applications. By integrating HP Insight Control and extending its functionality into Microsoft System Center, these customers can use 6 # IDC

7 a single console to manage their infrastructure at both the hardware level and the application level without having to switch back and forth between two different management consoles. HP Insight Control also ties in with Microsoft System Center Virtual Machine Manager, enabling customers to perform predictive failure on Hyper-V hosts and reduce downtime for their virtual machines. This works by detecting situations such as failure of a redundant power supply or redundant fan in a server, which would not bring the server down but would make the server no longer highly available. In these situations, the virtual machine would be automatically moved to another server in the environment, allowing the administrator to go in and remediate the problem, bring the server back up, and balance the load. Finally, HP Insight Control integrates with Microsoft System Center's bare-metal deployment capabilities to simplify deployment of Windows onto HP ProLiant servers. VMware vcenter Similar to its support for Microsoft System Center, HP Insight Control now supports deep integration with VMware vcenter. On its own, VMware vcenter provides management capability at the virtual layer; combined with HP Insight Control, customers can now manage both their physical and virtual assets from a single console. HP Insight Control is represented as a tab in the vcenter console and allows administrators to monitor system health, perform power optimization, view alarms, and take automated action based on alerts that come from HP Insight Control. HP Insight Control power optimization capabilities also extend those offered by vcenter; vcenter enables power management targeted to the data center or cluster level but not at the server level. The integration allows administrators to take advantage of HP Insight Control server-level power management capabilities from the vcenter console. HP Insight Control for Linux HP Insight Control for Linux (HP ICE-LX) is a Linux-based version of HP Insight Control. When integrating HP and open source technology, HP ICE-LX becomes a full-featured management tool for companies that require a Linux-based central management console. Like HP Insight Control, HP ICE-LX provides deployment, power management, remote management, and system discovery and health monitoring capabilities. It unifies the management of Linux-based servers, storage, power and cooling, and networked devices from a single console. HP Insight Dynamics Complementing HP Insight Control in HP's Insight Software portfolio, HP Insight Dynamics can help companies tackle a number of technology issues in new and innovative ways. This software delivers a number of key benefits: Continuous consolidation. HP Insight Dynamics enables organizations to optimize resources on a more continuous basis instead of managing server consolidation in one-off, piecemeal projects by simulating and identifying bestfit configurations based on different workloads and sets of server resources. It captures thousands of points of data every five minutes on resources such as 2010 IDC #

8 CPU, memory, network, disk, and even power at the individual server level and works both for HP infrastructure and for any x86-based servers or HP Integrity servers in the infrastructure. It allows ongoing rebalancing and repurposing of workloads, allows organizations to instantly see available infrastructure on which to deploy new workloads, and identifies servers that push their capacity limits and that could be rebalanced. Energy-aware capacity planning. HP Insight Dynamics provides the data and tools necessary to plan server capacity and power needs. It enables power usage planning for different scenarios and enables companies to see their best choices for provisioning and redeploying servers in an energy-efficient manner. High availability. Many organizations use complex, clustered configurations to provide high-availability failover capability to a handful of business-critical applications. By using HP Insight Dynamics to shift workloads to physical servers at alternative locations during periods of unplanned downtime, companies can bring "everyday" high availability to a broader range of applications, and with the recovery management capabilities of HP Insight Dynamics, companies can implement cost-effective disaster recovery with automated failover to remote metropolitan-distance sites. Dynamic infrastructure provisioning. Configuring, testing, and troubleshooting applications in multitier environments can be cumbersome and time consuming. With the infrastructure orchestration feature of HP Insight Dynamics, organizations can visually design and automatically provision infrastructure environments from pools of resources, including servers with storage and network connections. Driving ROI with HP Insight Control In 2010 IDC interviewed IT staff members from seven companies to conduct an ROI analysis of the benefits associated with using HP Insight Control solutions. This research found that customers were able to realize total benefits over a three-year period of more than $73,000 for every 100 users and that these benefits grew as more solutions were added to the mix. Three-year return on investment ranged from just under 450% for implementing a single component of HP Insight Control to over 600% for implementing all HP Insight Control components. These gains come from operational efficiencies and reduced hardware and software costs that companies can realize by improving their ability to deploy, monitor, optimize, control, and integrate their server infrastructure. Some of the key areas of benefit include: IT staff efficiencies. This was found to be the largest single area of benefit and represents IT staff time saved in areas such as managing and supporting both physical and virtual servers, deploying and migrating servers, and performing incident/help desk management. There is also a smaller effect on areas such as security management, change management, application management, and configuration database maintenance. 8 # IDC

9 User productivity savings. Improvements to end users' productivity is another important area of benefit. With many employees dependent on information technology to perform critical business tasks, reduced server downtime and better user-facing system performance can yield significant improvements to employee productivity. Protected revenue. Improved server performance and reduced downtime can also have a positive impact on revenue. This is true whether companies rely directly on their systems for revenue-generating activities (e.g., companies that engage in ecommerce) or whether the systems have a less direct effect on revenue (e.g., companies with telesales or call centers whose employees depend on customer relationship management or sales force automation systems). IT infrastructure savings. Areas of savings include efficiencies in power and cooling, hardware life-cycle cost savings, and avoided travel costs. IDC Analysis The competitive business environment is placing pressure on IT managers to simultaneously accelerate their IT capacity and maintain budget expenditures. The challenge to deliver enhanced levels of service-level agreements has become increasingly difficult due to increasingly complex infrastructures and the introduction of virtualization technologies. All indications suggest that IT budgets will not see substantial or even mild increases in the near term, leaving IT managers to seek ways to reduce and reappropriate spending. Operational expenses, such as server management and power and cooling, have grown to become significant cost factors in IT budgets, taking financial resources and staff time away from innovative initiatives that drive value to the business. IDC believes that server management tools are one method to achieve efficiency in IT operations as well as to mitigate risk and alleviate the burden on IT staff. As discussed throughout the paper, IT trends during the past decade have helped customers reduce capital expenditures, but the downside has been the significant growth in the "hidden" cost of IT, namely the spending on staff to maintain the growing server installed base. IDC estimates that this expense has been growing at eight times the cost of server spend. IT organizations cannot continue to operate under this model if they are expected to provide increased capacity and demonstrate higher service levels to meet tighter regulatory control requirements. Additionally, the mainstream adoption of server virtualization has introduced customers to new usage models for servers. By leveraging tools that allow administrators to move virtual servers across different physical servers, organizations can increase availability and reduce planned and unplanned downtime. Yet, we have seen that the management of this new virtual environment has put additional pressure on IT staff as all of these logical servers, both virtual and physical, must be administered in the same manner. Management and automation tools, along with the adoption of better governance practices and policies within each individual organization, will be fundamental to the continued success of this market IDC #
