How to Enhance Performance and Reduce Energy Costs in the MidmarketPage 2Executive Overview The world economy has pulled out of its worst recession since World War II and will stage a sluggish recovery in the coming years. Because recovery was largely due to massive public spending by governments, sentiment among small and medium business owners remains barely improved over that of a year ago. Cash positions have improved, but doubts over the sustainability of the recovery continue to linger. Yet a more robust turnaround is still somewhere off in the future. Small and midsized companies are continuing to defer hiring, as business owners are not yet confident enough about the economy to add employees. Recent economic conditions have changed the way that businesses operate. At the same time, the world is becoming smarter—more instrumented, interconnected, and intelligent. Midsized businesses have to manage increasingly large data pools and a customer base with higher expectations, without spending more on IT. IBM delivers leading technology solutions—smarter systems built for a smarter planet, which provide leadership quality, service and value to such businesses. In business, growth is good. Having technology and infrastructure capable of keeping up with growth is even better. Finding the right servers to meet your needs both today and tomorrow can be the key to sustaining that growth. More than simply equipment, servers are the foundation of a dependable IT infrastructure. IBM has announced a new generation of x86 servers—System x® and BladeCenter® systems and other supporting options—offering an unbeatable combination of performance, value, storage, and energy efficiency designed to help you improve service, reduce costs and manage risk. The new servers include: • System x3650 M3, x3630 M3, x3620 M3, x3550 M3, and x3250 M3 rack servers • System x3500 M3, x3400 M3, and x3200 M3 tower servers • BladeCenter HS22 and HS22V blade servers These new servers feature the Intel® Xeon® Processor 5600 Series, the next generation of intelligent server processors. With these new servers you gain the benefits of proven reliability, breakthrough performance and the operational advantages of using advanced server technology developed specifically for small and medium businesses. This paper shows how these new x86 servers, by integrating advanced technologies like IBM Systems Director Active Energy Manager™ and the IBM Integrated Management Module (IMM), offer an outstanding platform for virtualization and consolidation. Moreover, it’s a platform that’s easy to use and manage, allowing you to lower total cost of ownership, reduce development costs, increase performance within the same energy and cooling envelope and with continued investment protection, and dramatically increase workload performance.Server Refresh: A Smart Choice Your servers have done the job so far, but you’re seeing the strains of outdated technology, having to manage multiple systems and locations, and the growing footprint of piecemeal server management. Updated servers can also enhance the performance of new applications or operating systems. You need to make the right choices with your limited IT budget. With IBM servers based on the latest Intel Xeon processors, your business will have the headroom to handle bigger data loads and more people, while delivering the performance that your customers and business demand. And you can do so with fewer servers, not more. Updating your servers can offer you:
How to Enhance Performance and Reduce Energy Costs in the MidmarketPage 3 • Optimal support for the latest applications • New hardware with warranty support • The ability to consolidate servers through virtualization, to save space, run quieter, and simplify management • Reduced total cost of ownership due to lower maintenance costs, more efficient energy usage, fewer software licenses, and less downtime Dramatically Reduce Costs A longtime leader in the data center market, IBM uses a comprehensive understanding of customers’ evolving computing needs to continually produce new, standards-setting offerings across an array of product classes. Among the company’s leading-edge products are the System x3650 M3 and System x3550 M3 rack servers. Featuring innovative and energy-efficient designs, simplified IT management, and dramatic improvements in performance and function, the x3650 M3 and x3550 M3 set new cost-efficiency standards for the x86 processor-based server market. As IT professionals evaluate options for x86 server upgrades and additions, Technology Business Research (TBR), an independent information and market research firm, found that efficiency and an ability to reduce costs over the life of the server are key criteria in decision making in addition to reliability, product availability and management capabilities. Users are increasingly focused on how new infrastructure can help lower costs and improve operations versus the pure horsepower that a server offers. To that end, IBM focused its development on key feature areas that enable customers to lower costs or drive more utilization, ultimately painting a picture of high ROI. IBM’s System x lineup offers further benefits as the machines are part of IBM’s fabric of solutions, which include IBM software, IBM System Storage®, IBM Global Financing, and IBM Global Services. This allows customers to maximize their returns by tailoring their broader IT infrastructures, including their System x servers and adjunct devices, software and services, to solving their specific business needs. Additionally, an IBM engineering research study showed that IBM’s new rack servers can reduce annual energy costs by more than $100 per year per server over previous x3550 and x3650 models through innovative, energy-smart designs and simplified management. Integrating two Xeon 5600 series processors with Intel QuickPath Technology and Intel Turbo Boost Technology, the IBM servers deliver dramatic performance improvements over previous generations, while also offering low acquisition cost. Dramatic performance gains and new virtualization solutions can offset the initial outlay in fewer than 3 months1. Designed to be growth engines for expanding businesses, the x3500 M3 and x3400 M3 tower servers are dual-socket servers equipped with Xeon Processor 5600 series processors. These are designed to offer high reliability as well as extraordinary performance and outstanding power efficiency to help reduce costs. Figure 1 shows the x3650 M3, which makes possible the dramatic server consolidation by replacing 5-year-old rack and tower servers with the new System x servers. (The x3400 M3, x3500 M3, and x3550 M3 servers offer the same kind of consolidation potential as the x3650.) 1 Based on detailed IBM analysis.
How to Enhance Performance and Reduce Energy Costs in the MidmarketPage 4 Figure 1. IBM System x3650 M3 Rack server offers 20-to-1 consolidation In addition to the energy savings enabled by the more efficient processors, the new IBM servers also support 1.5V DDR3 memory, which is 15% more energy-efficient than the older DDR2 memory (and even more so than fully-buffered memory), as well as 1.35V DDR3 memory, which is 19% more efficient than even 1.5V DDR3 memory. With servers now containing as much as 288GB of RAM, this energy savings is significant. Also, the servers incorporate more efficient power supplies (up to 93% efficiency), transistors, and voltage regulator modules (up to 88%) that help reduce energy costs, along with 2.5-inch HDDs that use up to 80% less energy than 3.5-inch drives, and solid-state drives (SSDs) that consume only 2W of power. In addition, integrated BladeCenter 10Gb Ethernet switches can be more than 95% more energy efficient than external 2 switch offerings . Finally, IBM Systems Director Active Energy Manager provides you with the tools necessary to monitor actual energy usage (not simply the theoretical maximum power draw), track trends, and even cap energy usage at a predetermined point. From a management standpoint, to use features beyond that of the standard Baseboard Management Controller (BMC) in the older servers, you had to spend several hundred dollars to purchase an IBM Remote Supervisor Adapter II. Now, that functionality (such as remote management and IPMI 2.0) is incorporated inside the new IBM Integrated Management Module 3 (IMM), standard in the new servers . Dramatically Increase Workload Performance Get great performance, energy and cost-efficiency, and plenty of room to grow and virtualize in the future with the next generation of IBM x86 servers based on the Xeon 5600 series processors. These servers offer you maximum performance for heavy workloads, while reducing energy consumption when workloads are light. It all adds up to intelligent performance that keeps energy costs low. Application performance is critical for day-to-day business operations, as well as for creating new products and services, increasing competitiveness, and reaching new customers. For the past2 Based on the integrated BladeCenter BNT L2/3 10Gb Ethernet per-port power consumption of 3.1W and external Cisco Catalyst 6500 L2/3 10Gb Ethernet per-port power consumption of 94.3. 3.1/94.3 = 3.3. 100-3.3 = 96.7% savings.3 The x3200 M3, x3250 M3, x3400 M3, x3550 M3, and x3650 M3 require an optional Virtual Media Key (VMK) to enable the remote presence features of the IMM. The VMK is standard in the x3500 M3. The HS22 and HM22V do not require a VMK for remote presence.
How to Enhance Performance and Reduce Energy Costs in the MidmarketPage 5 decade, IT has rapidly added low-cost hardware to accommodate business growth, and many data centers are now stretched to capacity in terms of power, cooling, and floor space. By refreshing your data center infrastructure with higher performance, more adaptive, power- conscious servers, you can deliver additional capability and scalability within the same energy and space footprint, staying ahead of ever-increasing business demands. The Xeon 5600 series processors bring together a number of innovative technologies to deliver intelligent performance. New features include: • Intel Turbo Boost Technology4 — Turbo Boost dynamically turns off unused processor cores and increases the clock speed of the cores in use, by up to two model frequencies. For example, with three cores active, a 3.33GHz 6-core X5680 processor with 3-6 cores active can run the cores at 3.46GHz. With only one or two cores active, the same processor can run those cores at 3.6GHz. Similarly, a 3.46GHz 4-core X5677 processor can run at 3.6GHz or even 3.73GHz. When the cores are needed again, they are dynamically turned back on and the processor frequency is adjusted accordingly. • Intel Hyper-Threading Technology (Intel HT) — HT lets today’s well-threaded applications make the most of every clock cycle. Multi-threaded software applications can execute threads in parallel within each processor core. • Intel QuickPath Technology — Along with the integrated memory controller, Intel QuickPath Technology helps speed traffic between processors and I/O controllers for bandwidth- intensive applications. With the Xeon 5500/5600 series processors, Intel has diverged from its traditional Symmetric Multiprocessing (SMP) architecture to a Non-Uniform Memory Access (NUMA) architecture. The Xeon 5600 series processors are connected through a serial coherency link called Intel QuickPath Interconnect (QPI). QPI is capable of 6.4, 5.6 or 4.8 GT/s (gigatransfers per second), depending on the processor model. This allows the new servers to deliver as much as 25.6 GB/s—up to 3.5x the bandwidth of previous-generation servers. As a result of these and other improvements, the 5600 series processors offer up to 54% more performance than a same-frequency Xeon 5500 processor, or the same performance with up to 30% less energy consumption5. Dramatically Increase Performance with Continued Investment Protection Rack and tower servers are not the only area to benefit from new-generation technology. The BladeCenter HS22 and HS22V blade servers also offers great performance, balanced with flexible configuration options and simple management. All together, this creates an efficient server designed to run a broad range of workloads exceptionally well. You can also mix-and-match the HS22/HS22V with other BladeCenter blades and various operating systems in existing chassis, including the BladeCenter S and BladeCenter H, for unmatched investment protection, incredible flexibility and deployment choice. And with features like Unified Extensible Firmware Interface (UEFI), the IBM Integrated Management Module (IMM), and IBM Systems Director you can further simplify systems management and future-proof your infrastructure. Compared to earlier-generation Xeon processor-based servers, HS22/HS22V blade servers can help improve the economics of your data center with: 6 • Up to 99% IT footprint reduction from server consolidation4 Intel Turbo Boost Technology Is not available in all models of Intel Xeon processor 5600 series.5 Based on Intel data.6 Data center floor space cost estimate used is $500 per square foot, average 8 square feet per standard enterprise 42U rack. IT footprint compares 1U per rack server vs. 0.5U per HS22/HS22V blade. 14 HS22/HS22V blades in 9U (.21 of one 42U rack) BladeCenter H chassis provides equal or greater performance than 310 x346 2U rack servers inside 14.76 rack enclosures, for a savings of 14.55 racks or 98.5%. In terms of floor space that would save approximately 117 sq. ft. (613U). (Realistically, in most data centers 2U rack servers cannot be populated that densely, due to air flow and power issues. So the IT footprint savings would be even greater for BladeCenter H.)

Dramatically Increase Performance within the Same Energy Envelope Midsized companies can now enjoy the dramatic increase in performance with new HS22 blades without increasing their data center space or energy footprint. Figure 3 illustrates how you can expand your IT infrastructure without bearing the burden of an increase in power cost. (This example shows new low-voltage 60W HS22 blades used in a 2005-era BladeCenter E chassis7 Using a 22.1-to-1 performance ratio of today’s HS22/HS22V to a 2005 xSeries 346 2U rack server, 1 BladeCenter H chassis containing 14 HS22V blades would provide the computing performance of approximately 310 2U rack servers. 1 BladeCenter H chassis containing 14 HS22V blade servers consumes an average of 4,382W. 310 2U rack servers consume 119,040W. Thus, the energy savings for replacing 310 x346 2U rack servers with 1 BladeCenter H chassis is 96.3%. - HS22/HS22V blade server with "reduced voltage" processor configuration: 2S 6C Xeon X5670 (Intel Turbo Boost Technology up to 3.33GHz and 12MB cache) with 24GB (12 x 2GB) of DDR3 PC3-10600R memory, and 1 SSD; average power draw with chassis burden = 313W under load, SPECjbb2005 = 875,369 bops. - x346 2U rack server: 2S 2C Intel Xeon (2.8GHz 2MB cache) with 8GB (8 x 1GB) and 1 HDD; average power draw = 384W under load, SPECjbb2005 = 39,585 bops.8 Performance and energy savings calculations are based on actual SPEC results and IBM estimate of SPECint_rate2006: Rack to blade comparisons: 2011 HS22/HS22V to a 2005 xSeries 346 2U rack server SPECjbb2005 ratio = 23.1-to-1: - HS22/HS22V blade server configuration: 2S 6C Xeon X5680 (Intel Turbo Boost Technology up to 3.60GHz and 12MB cache) with 24GB (12 x 2GB) of DDR3 PC3-10600R memory, and 1 SSD; average power draw with chassis burden = 372W under load, SPECjbb2005 = 915,323 bops - x346 2U rack server: 2S 2C Intel Xeon (2.8GHz 2MB cache) with 8GB (8 x 1GB) and 1 HDD; average power draw = 384W under load, SPECjbb2005 = 39,585 bops. 2011 HS22/HS22V to a 2006 System x3650 2U rack server SPECjbb2005 ratio = 7.95-to-1: - HS22/HS22V blade server configuration: 2S 6C Xeon X5680 (Intel Turbo Boost Technology up to 3.60GHz and 12MB cache) with 24GB (12 x 2GB) of DDR PC3-10600R memory, and 1 HDD; average power draw with chassis burden = 372W under load, SPECjbb2005 = 913,456 bops. - x3650 2U rack server: 2S 2C Xeon 5160 (3.00GHz 4MB cache) with 8GB (8 x 1GB) and 1 HDD; average power draw: 324W under load, SPECjbb2005 = 114,941 bops.
