Business Value of Blade (Livre Blanc en Anglais)

  1. 1. WHITE P APER Business Value of Blade Sponsored by: HP Jed Scaramella Randy Perry April 2012 EXECUTIVE SUMMARYwww.idc.com Today, a companys datacenter is tightly integrated with its day-to-day business operations. Companies are increasingly looking to their IT as a means to gain a competitive advantage in the market rather than simply as a means of supporting business functions. IT applications and services have become a critical element in how companies interact with their customers, deliver new products and services, andF.508.935.4015 improve their own workforce productivity. Yet even though IT organizations are charged with delivering an expanding base of workloads and seemingly higher degrees of service-level agreements (SLAs), they are also challenged with constrained budgets and overburdened staffs. In response, ITP.508.872.8200 organizations must seek efficiencies in their operations and shift to a more agile infrastructure that is flexible enough to adapt to future changes in the business. Over the past decade, IDC has seen the industry move more toward distributed environments as lower-cost x86 systems have increased their share of workloads.Global Headquarters: 5 Speen Street Framingham, MA 01701 USA While this migration has enabled customers to control capital expenditure with lower- cost servers, the increased operational costs of managing the x86 base are taxing IT budgets, making it difficult to fund and staff new initiatives. This paper examines how eight midsize companies spanning the education, healthcare, media, retail, research, and telecommunications (service provider) industries were able to reduce their annual IT infrastructure cost per user by almost 25% by migrating to a blade platform. Reduced requirements for staff time and resources, hardware infrastructure, and facilities drove these savings. The integrated nature of the blade platform delivers efficiencies in system management, monitoring, and provisioning. The HP BladeSystem utilizes HP Insight Management software to automate key management processes, including a systems physical deployment, configuration, and problem management. As measured by IT infrastructure cost per user per year, companies implementing blades saved an average of $55 per user per year in reduced IT infrastructure staff time (as the company can apply that saved time to other business IT initiatives) and $56 per user per year in reduced hardware and software costs. HP BladeSystem ProLiant server blades enabled these companies to consolidate physical servers and components while still maintaining the same workload capacity and performance. Blade technologies, such as HP Virtual Connect, reduced networking and hardware costs by enabling up to four FlexNICs per physical NIC port; a single HP Virtual Connect interconnect module eliminates four switches.
  2. 2. The study also demonstrated that virtualizing HP ProLiant servers further improved ITinfrastructure savings. By deploying a greater number of virtual machines (VMs) perphysical server blade, IT organizations were able to further reduce IT infrastructuresavings by 17.1%.IDC research indicates that available power, not floor space, determines the extent ofa datacenters capacity. HP Thermal Logic technology enables the HP BladeSystemto pool and share the power and cooling resources. The combined solution thenutilizes management software to efficiently deliver those resources based on theperformance level required. This study shows how customers reduced power costsand avoided facilities expansion, saving an average of $17 per user per year.In addition to illustrating the IT operations cost savings, the study also shows howmigrating to a blade environment improved IT availability. Relative to traditional serverenvironments, customers with virtualized blades incurred 75% fewer server incidentsper year and reduced server downtime hours by an average of over 80%.IDC believes that the HP BladeSystem delivers improved return on infrastructureinvestment for customers, creating a flexible IT environment that provides for botheasier IT management and easier adaptation to the changing needs of the business.IDC estimates that over a three-year period, the companies in the study saw theirimplementation of a bladed infrastructure deliver a return on investment (ROI) of over250%, and cumulative savings from the implementation paid back the full investmentwithin a period of just over 10 months.WHATS CHANGING THE G AME ?Operating Todays IT Environment withLimited Budget and ResourcesIn todays competitive marketplace, customers are evaluating how their ITorganization can run more efficiently and drive additional value to the business. Firstamong the challenges facing the managers of IT organizations is the fact that evenwith constrained budgets, they still must continue to deliver on increasingly stringentSLAs, build new applications, and maintain high levels of application availability. Torespond to these challenges, IT managers must build their infrastructure on platformsthat can deliver operational efficiencies and maintain the flexibility to adapt to futurechanges in business demands.Furthermore, the datacenter has become more tightly integrated with day-to-daybusiness operations. IDC has observed that companies are placing greater emphasison the operations of their IT environments not only to gain a competitive advantage inthe market but also because IT services and applications have become a criticalelement in day-to-day business and workforce productivity. An unfortunate reality isthat enterprises are asking IT organizations to do more with less, pressuring them toreduce their operational expenses. This can become a significant obstacle toincreasing application availability, improving service levels, and providing higherlevels of IT flexibility.2 #227508R1 ©2012 IDC
  3. 3. Challenges with Distributed x86 ServersEnvironmentsOver the past decade, IDC has seen x86 servers account for an increasing share ofIT workloads. x86 servers started out as an extension of the PC market and providedbusiness units, which were previously unable to secure space on the larger systems,the means to set up IT systems. Development on these platforms set in motion apositive feedback loop that drove expansion of IT capabilities via x86 that in turndrove still more development and innovation to the x86 platforms. This pattern hasresulted in an increasing number of IT applications migrating to x86 platforms.Because the price point for smaller x86 systems is much lower than that of monolithicbusiness systems, customers have been able to use x86 to expand server capacitywhile controlling their capital expenditure. However, this migration to a distributedenvironment created a more complex infrastructure that resulted in higher operationalcosts.As Figure 1 illustrates, todays IT organizations face rising operational expenses,power and cooling constraints that limit IT capacity expansion, and IT staffsoverburdened by manual tasks. The management and administration costsassociated with x86 servers have grown to eclipse costs in all other categories. Thepersonnel costs required to manage and maintain the x86 server base consume themajority of IT budgets, leaving little time and few resources for value-add initiativessuch as building new applications.Additionally, the power and cooling of servers is a top-of-mind issue for ITorganizations, as the growth in server energy expense has outpaced spending onservers themselves; server energy expense grew at a compound annual growth rate(CAGR) of 9.5% compared with a server revenue CAGR of -2.6%.©2012 IDC #227508R1 3

Going forward, IT managers need toimplement solutions that can considerably reduce costs by: Increasing IT hardware utilization. Research indicates that only a fraction of most servers total capacity is typically utilized in a distributed environment. The overprovisioning results in wasted rack space as well as increased power, cooling, bandwidth, and operational costs. Simplifying management and increasing flexibility. As currently deployed, most server configurations are static, hardwired, and difficult to change. Too much manual coordination is required to maintain applications and server configurations, involving too many people to perform too many manual steps. Improving server energy efficiency. IDC finds that the primary driver behind efforts to improve energy efficiency is to ensure the availability of IT to the business by averting risks posed by power and cooling challenges. To avoid costly new buildout, IT must deploy more systems with the current available power.4 #227508R1 ©2012 IDC
  5. 5. These requirements become imperatives because distributed server environmentscan often consume large amounts of space, power, and IT staff time. The costsassociated with provisioning, monitoring, and managing servers have escalated,challenging IT organizations to seek systems and tools to help them lower the overallcost of IT operations.BLADE SYSTEMS DRIVE EFFICIENCY ANDSIMPLICITY TO THE IT ENVIRONMENTMethodologyIn the fall of 2010, IDC interviewed eight midsize companies, referred by HP, that hadmigrated 19% to 100% of their server environment to blades. These United States–based organizations represent experiences from the education, healthcare, media,retail, research, and telecommunications (service provider) industries.The Results: Blades Deliver 25% Cost SavingsEfficiencies Across the IT EnvironmentThe customer interviews and IDC ROI modeling make clear that blades deliver costsavings in several areas (see Table 1); yet there are three main categories ofefficiency improvements: IT staff time and resources. The integrated nature of the blade platform allows for centralized management of all servers and components within the chassis. The centralized management results in more efficient methods of provisioning, monitoring, and managing. These efficiencies in turn reduce the amount of IT staff time required for IT infrastructure administration, allowing companies to apply that newly available staff time to other activities more directly related to the business, such as business application expansion or enhancement. As stated previously, companies implementing HP BladeSystem in their environment saved an average of $55 per user per year in reduced IT infrastructure staff time. IT hardware infrastructure. Migrating to a blade environment enables customers to consolidate physical servers while maintaining the same workload capacity and performance, which reduces capital expenditure on hardware. IT organizations are able to improve IT resource utilization rates by reducing the numbers of servers, a factor that is further enhanced through virtualization. Companies implementing blades saved an average of $56 per user per year in reduced hardware and software costs. IT facilities. Blades reduce power and cooling consumption due to the integrated platform and efficiencies gained through shared power and cooling components. On average, companies in this study reduced power costs and avoided facilities expansion, saving an average of $17 per user per year.©2012 IDC #227508R1 5

IT organizations running virtualization performance." — Manager of Infrastructure, Healthcareon blades were able to further reduce IT infrastructure, which resulted in additional Providercost savings of 17.1% (refer back to Table 2). As an increasing number of VMs aredeployed per physical server blade, IT is able to further reduce hardware expenditure,as well as licensing fees and the cost of tools, by purchasing the appropriate amountof system software for the reduced hardware footprint.Enhanced ConnectivityThe blade platform is an integrated architecture that matches well with the goals ofvirtualization, yet the running of a higher number of virtual machines on physicalservers can introduce challenges in the form of I/O bottlenecks. To eliminate theseobstacles, HP Virtual Connect enables up to four FlexNICs per physical NIC port.Because only one HP Virtual Connect interconnect module is needed for fourFlexNICs, compared with the four switches that would have been previously required,blade infrastructure costs and support burden are reduced. Customers can ensuremore efficient use of networking resources through the HP Virtual Connect capabilityof throttling bandwidth at increments of up to 100MB, matching the application to theappropriate amount of bandwidth. With HP Virtual Connect, we avoid having a lot of switches, a lot of cables, and a lot of additional gear. But it more or less pays for itself within the first year of implementation. Im avoiding a whole lot of cabling and a whole lot of external switches to then switch back into the chassis themselves. For a fully loaded chassis, I think were avoiding 2–3 switches that would cost about $500 each. — Vice President, Sales and Operations, Opus Interactive©2012 IDC #227508R1 7
  8. 8. Blade Management Tools Drive IT Staff ProductivityFigure 3 examines how customers that migrated to a blade environment were able toincrease the efficiency of their IT staff. The wire-once, ready-to-deploy nature of bladesreduced the physical deployment by 75.1% and system setup and configuration by46.1%. The ongoing operations of IT also become more efficient as problemmanagement was reduced by 52.3% and maintenance was reduced by 49.4%.FIGURE 3IT Staff Reduction per Task Server deployment (physical) Problem management "The average full Maintenance chassis that weve got pulls about 8–15 amps of power System setup and conf iguration running full load.

HP Insight Management is a suiteof management tools designed to enable simple and reliable provisioning, monitoring,and control of the HP BladeSystem infrastructure. Because key managementprocesses are automated, less staff time is required. This ensures that IT resourcesare focused on more value-added initiatives. Elements of HP Insight Softwareinclude: HP Systems Insight Manager (SIM) provides a single, integrated view of all infrastructure resources and delivers core management services for discovery, monitoring, and control. HP Insight Control software provides comprehensive server health monitoring, imaging, power management, remote management, and vulnerability management.8 #227508R1 ©2012 IDC
  9. 9.  HP Matrix Operating Environment provides advanced management capabilities, enabling physical and virtual resources to be managed in exactly the same way and automated resource provisioning through a self-service portal.Power and CoolingHP BladeSystem incorporates HP Thermal Logic technology to help HP customersachieve greater power and cooling efficiencies in their IT environments. HP ThermalLogic includes technologies from system to enclosure, enables server infrastructuresto pool and share power and cooling resources, and then utilizes management toefficiently deliver those resources based on the performance level required.The HP BladeSystem chassis utilizes Platinum Power supplies with 94% efficiency forincreased energy efficiency. Additionally, the HP Dynamic Power Saver modeenables more efficient use of power in the server blade enclosure. During periods oflow server utilization, the HP Dynamic Power Saver places power supplies in standbymode, incrementally activating them to deliver the required power as demandincreases. HP Power Regulator, built for ProLiant, dynamically changes each serverspower consumption to match the needed processing horsepower, thus reducingpower consumption automatically during periods of low utilization.A datacenter is built with a specific maximum power capacity, and power and cooling— not floor or rack space — is often the limiting factor in determining the computepower in any given facility. Unfortunately, power in the datacenter is rarely efficientlyallocated, and the full power budget envelope is seldom used.

IDC used the following three-step method forconducting the ROI analysis: Gathered quantitative benefit information during the interviews using a before-and-after assessment. In this study, the benefits included IT staff productivity increase, user productivity increase, and IT cost reduction. Created a complete investment (three-year total cost analysis) profile based on the interviews. Investments go beyond just the solutions hardware and software. IT departments spent staff time installing and configuring the new solution, removing old equipment and/or software, and then maintaining the new solution over three years. Ancillary costs directly related to the solution, such as user input to planning, outsourced installation, configuration or maintenance costs, and IT staff or user training, are also included in the analysis. Calculated the ROI and payback period. IDC conducted a depreciated cash flow analysis of the benefits and investments over a three-year period.Because the full benefits of the solution are not available during the deploymentperiod, IDC prorates the benefits on a monthly basis and subtracts the appropriateamount for the deployment time from the first-year savings.10 #227508R1 ©2012 IDC
  11. 11. IDC uses a discounted cash flow methodology to calculate the ROI and paybackperiod. ROI is the ratio of the net present value (NPV) and discounted investment.Payback period is the point at which cumulative benefits equal the initial investment.IDC uses a standard 12% discount factor, which allows for risk and the missedopportunity cost that could have been realized using that capital.The three-year ROI analysis shows that on average, the companies in this studyspent $8,074 per 100 users deploying and maintaining HP BladeSystem and received$28,326 per 100 users in benefits for an NPV of $20,252. The companies sawpayback in 10.2 months and achieved an ROI of 251% (see Table 3 and Figure 5).

  13. 13. CHALLENGES/OPPORTUNI TIESWhile the study demonstrates the improved ROI, IDC acknowledges that bladevendors still face some challenges. Identifying expenses may not always be asstraightforward in IT organizations as in other business units. Up-front costs, such asthe cost of hardware or software licenses, are tangible and relatively easy to see.However, some abstract costs, such as hardware cabling costs, facilities charges,and personnel hours needed to configure and manage the environment, are often notaccounted for with precision. A more sophisticated ROI analysis is required todemonstrate the full benefits of and cost savings from blade environments.A 2010 IDC study, IDC Blade Market Survey: The Dynamic Platform for the FutureDatacenter, shows how the potential obstacles to blade deployments have decreasedin recent years. The current generations of blade technologies have vastly improvedover the initial offerings of the early 2000s. Additionally, customers have a betterunderstanding of the technology, and the improved services from vendors have madeit easier to deploy blades into IT environments. However, the top-ranking obstaclesremain the perceived price premium over other server form factors and organizationalissues such as internal or management resistance to the platform.This finding shows that HP and other blade vendors face a number of nontechnicalchallenges as they seek to deliver blade-based solutions. IDC market data indicatesthat blades represent 13.8% of the total worldwide server investment. To drive furtherblade adoption, vendors will need to convey the message of how blades deliver abetter total cost of ownership than traditional environments.CONCLUSIONThis IDC ROI analysis indicates that customers can achieve considerable cost savings andimprove the agility of their infrastructure by migrating to an HP BladeSystem environment.The companies in this study were able to pay back their initial investment in less than ayear, a significant factor given the financial constraints most IT organizations are facing.IDC believes that the datacenter of the future will require IT organizations to increase theutilization of their hardware, simplify their management, and improve the energy efficiencyof servers. By leveraging HP BladeSystem and technologies such as HP Insight Control,HP Virtual Connect, and HP Thermal Logic, customers will be able to reduce theiroperating expenses and improve the flexibility of their IT environment. As a result, agreater portion of IT budget and staff time can be allocated to new initiatives that drivevalue back to the business.Copyright NoticeExternal Publication of IDC Information and Data — Any IDC information that is to beused in advertising, press releases, or promotional materials requires prior writtenapproval from the appropriate IDC Vice President or Country Manager.
