ExecutiveSummary Virtualization using x64 servers can help enterprises consolidate server workloads and reduce costs, while creating a dynamic IT inrastructure that makes provisioning and managing servers, streamlining sotware development, and providing better business continuity easier. No wonder 54 percent o enterprises and 53 percent o small and midsize business have either implemented x86 server virtualization already or will do so in the next 12 months, according to Cambridge, Mass.-based analyst rm Forrester Research Inc.

Virtualization’s advantages are especially welcome in today’s dicult economy, in which IT budgets and personnel are likely to remain under pressure or some time. To achieve these benets, however, IT executives must choose the right combination o virtualization sotware and host servers. That combination is Microsot Windows Server 2008 Hyper-V™ on servers powered by Quad-Core AMD Opteron™ processors.

This white paper highlights the power o the Microsot-AMD combination or server virtualization. In doing so, it explores the advantages o server virtualization with Hyper-V, the unique capabilities o AMD Opteron processors to optimize virtualization perormance, and the partnership between AMD and Microsot, which delivers on the promise o server virtualization—exceptional perormance, scalability, availability, manageability, and cost eectiveness.

Microsot Windows Server Hyper-V: Virtualizationoreveryone Introduced in 2008 as part o Microsot Windows Server 2008, Hyper-V delivers next-generation hypervisor-based virtualization technology. A virtualization platorm that provides outstanding fexibility, Hyper-V also oers dynamic, reliable, and scalable platorm capabilities. Additionally, it provides total scripted control o a set o connected virtual machines, ensuring ease o deployment, management, and use. The result is an agile and dynamic data center environment. Key eatures o Hyper-V include:

Next-generationhypervisor. Hyper-V eatures 64-bit hypervisor technology, which creates a “hypervisor layer” or virtual machines that runs directly on top o the hardware and below the operating system. By eciently managing virtual machine memory, processors, I/O, and scheduling, Hyper-V delivers the highest levels o resource control and virtualization perormance. In act, Hyper-V perorms so well that Microsot uses it to power major online services that receive millions o hits each day. These include all o the Microsot TechNet (technet.microsot. com) and Microsot Developer Network (msdn.microsot.com) Web sites and hal o microsot.com, which receives an average o one billion hits per month.

Scalability.Thanks to the ecient architecture o its hypervisor, Hyper-V has low processor overhead, leaving plenty o power to virtualize workloads. By enabling virtual machines to take advantage o the advanced capabilities in today’s x64 hardware, such as multicore technology, improved disk access, and greater memory, Hyper-V maximizes scalability and perormance o the virtualization platorm. Hyper-V can support up to 1TB o memory on the host and up to 16 logical processors, with up to 64GB o memory per virtual machine. It can create virtual machines with up to our virtual processors to support workloads that leverage multiprocessor capabilities.

Highavailabilityandbetterbusinesscontinuity.Consolidation o numerous physical servers onto one can be problematic i the host server ails. Microsot has addressed this by building high availability into the Windows Server 2008 Hyper-V platorm. The Datacenter and Enterprise editions o Windows Server include server clustering technology, which enables automatic ailover o virtual machines to a dierent clustered system in case o hardware ailure. With the multisite clustering capability o Windows Server 2008, you can set up a remote cluster so that i your primary data center or a remote oce ails, you can recover to a remote data center.

Easymanageability. With Hyper-V you don’t have to create a separate management inrastructure or your virtual environment. Hyper-V integrates with Microsot System Center Virtual Machine Manager and Microsot System Center Operations

Manager, as well as with third-party management tools. This lets you manage your physical and virtual resources from a single console. Microsoft, for example, provisions new servers using Hyper-V with Virtual Machine Manager. As a result, what used to take weeks or physical server provisioning now takes less than one hour.

Flexible deployment and licensing. To appeal to organizations o every size and budget, Hyper-V oers exible deployment and licensing options. Hyper-V is part o the Windows Server 2008 operating system. The Standard Edition o Windows Server 2008 comes with a license or one virtual machine; the Enterprise edition includes our virtual machine licenses; and the Datacenter edition includes unlimited virtual machine licenses. In addition, Microsot Hyper-V Server 2008, a standalone version o Windows Server 2008 Hyper-V, is available as a ree download on the Microsot Web site (see www.microsot.com/servers/hyper-v-server).

AMD Opteron processors: Optimized for virtualization Top virtualization perormance requires host servers optimized or virtualization, such as servers powered by Quad-Core AMD Opteron processors. AMD has a long history as a leader in x64 technology, having introduced the frst 64-bit server processor in 2003 and the frst dual-core processor in 2004. The current range o Quad-Core AMD Opteron processors, introduced in late 2008, oer industry-leading virtualization perormance and energy efciency, thanks to key eatures such as these:

Leading-edge technology. The current generation o Quad-Core AMD Opteron processors eatures 45nm technology, a leading-edge abrication process that enables enhanced transistor designs, aster interconnect circuitry, and greater energy efciency. A larger L3 cache speeds memory-intensive applications such as virtualization, as does high-speed DDR2-800 memory. And higher clock speeds boost perormance o all applications.

Direct Connect Architecture. All o AMD’s x64 processors eature Direct Connect Architecture, which eliminates the bottleneck o a ront-side bus. Instead, the processor cores are directly connected to memory, the I/O subsystem, and any other processors in the confguration by high-bandwidth HyperTransport™ links. Moreover, the memory controller is located on the processor die instead o on the motherboard. The upshot is that AMD’s architecture improves scalability, reduces latency, and boosts perormance o memory- and I/O- intensive virtualization applications.

Hardware-assisted virtualization. AMD Opteron processors eature AMD-Virtualization (AMD-V) technology, a set o hardware extensions to the x64 architecture designed to improve the efciency and reduce the overhead o virtualization sotware. • AMD-V features Rapid Virtualization Indexing (RVI), which helps accelerate

the perormance o many virtualized applications by enabling hardware-based virtual machine memory management. RVI allows virtual machines to directly manage memory utilizing hardware rather than sotware resources, reducing hypervisor cycles and the associated perormance penalty usually associated with virtualization. The result is more virtual machines per server core. • AMD-V speeds up “world switch time” or up to 25 percent aster switching between virtual machines. • AMD-V Extended Migration with Windows Server 2008 R2 will provide live migration o virtual machines across all available AMD Opteron processor generations, protecting investments in AMD-powered servers and enabling a more reliable and adaptable IT environment.

Efcientpowermanagement. Enhanced AMD PowerNow!™ technology extends AMD’s leadership in perormance-per-watt by building power management into the processor. It allows each processor core to vary its requency based on the specic needs o the application, and decreases power consumption by enabling per-processor power management in multisocket systems.

Broadsupportbyservermanuacturers. Major server manuacturers such as Dell® and Hewlett-Packard utilize AMD Opteron processors in blade and rackmount servers optimized or virtualization. Such servers oer high memory and I/O capacity to meet the needs o demanding virtualization applications.

Conclusion Clearly, server virtualization oers numerous benets to enterprise IT departments. By improving IT eciency, reducing complexity, and lowering costs or hardware, data center inrastructure, and IT management, server virtualization can help enterprises weather the storm o a dicult economy.

Microsot Windows Server 2008 Hyper-V virtualization sotware running on servers powered by Quad-Core AMD Opteron processors is the smart choice or realizing these benets.

IT executives who select the AMD-Microsot team can choose rom a wide range o virtualization-optimized blade and rack-mount servers rom Dell, Hewlett-Packard, IBM, and others that have been qualied or Hyper-V. And Hyper-V’s varied licensing and deployment options are suitable or every situation and budget. What’s the bottom line? Lower ownership costs and aster return on investment or your virtualization deployments.

Appendix B: Case study: ServiceU fnds the golden ticket ServiceU Corp. is a ast-growing, midsized provider o Web-based event management sotware to organizations ranging rom Fortune 500 companies to nonprots, schools, and churches. With customers based in all 50 states and 15 countries, the Memphis, Tenn.-based company can’t aord to be ofine or any length o time, so it needs technologies oering high IT perormance and availability.

In mid-2007, ServiceU began investigating solutions to maximize inrastructure eciencies, including power and space, and increase data center manageability, while continuing to improve perormance.

“Because we host our sotware or our customers, the reliability and perormance o our servers is mission critical,” says Tim Whitehorn, ServiceU’s CEO. “We can’t deploy new technology just because it’s new—it must provide signicant benets to our customers. That’s why we chose to deploy Hyper-V on AMD [Opteron processor-based systems]. This is truly a big win or our customers and or us.”

Ater implementing Hyper-V on AMD Opteron processor-based Dell PowerEdge™ 2970 servers at all three o ServiceU’s data centers, the company reduced its number o physical servers by 35 percent. It also lowered power utilization at the Memphis data center by up to 60 percent, giving ServiceU signicant capacity or uture expansion.

ServiceU’s IT executives were impressed by how well AMD-V technology works in concert with Hyper-V to simpliy hardware inrastructure and data center management. In addition, they were pleased with Hyper-V’s seamless installation and overall simplicity.

David P. Smith, chie technology ocer at ServiceU, sums up the AMD-Microsot virtualization experience this way: “We were blown away by the results we achieved, and are now rm believers in the AMD Opteron processor and Microsot’s Hyper-V technology.”
