1 Based on IBM Study. The virtualized system count and energy savings were derived from several factors: A performance factor of 2.79X was applied to the virtualization scenario based on SPEC® results source: www.spec.org. System p 570 (16-core, 8 chips, 2 cores per chip, 4.7 GHz) SPECint_rate2006: 466, as of 8/20/2007; HP Integrity rx7640 (16-core, 8 chips, 2 chips per core, 1.6 GHz) SPECint_rate2006: 167 as of 8/20/2007. A virtualization factor of 3X was applied to the virtualization scenario using utilizations derived from studies conducted by Alinean available at www.ibm.com/services/us/cio/optimize/opt_wp_ibm_systemp.pdf (PDF, 74 KB). A factor of 2X was used to represent the ability to install two 16-core System p 570 systems in a single rack. Power consumption figures of 5600 W for the IBM System p570 and 2128 W for the HP rx7640 were based on the maximum rates published by IBM and the typical maximum power consumption published by HP. Source for the HPIntegrity rx7640 information is QuickSpecs HP Integrity rx7640 Server dated August, 2007. It can be found at www.hp.com/products/quickspecs/12470_div/12470_div.pdf (314 KB). Air conditioning power requirement estimated at 50% of system power requirement. Energy cost of $.0928 per kWh is based on 2007 YTD US Average Retail price to commercial customers per US DOE at www.eia.doe.gov/cneaf/electricity/epm/table5_6_b.html as of 8/20/2007. Datacenter floor space cost was estimated as of 8/20/2007 based on Alinean, Inc.'s ROI Analyst software. The reduction in floor space, power, cooling and software costs depends on the specific customer, environment, application requirements, and the consolidation potential. Actual numbers of virtualized systems supported will depend on workload levels for each replaced system.
2 "Impact of IBM System p Server Virtualization", Transforming the IT Value Equation with POWER6 Architecture. International Technology Group, 05/2007. Study methodology: Companies in financial services, manufacturing and retail with $15 Billion+ revenues focusing on UNIX® large enterprise environments with multiple, broad-ranging applications. Study compared the cost of the company's workloads running on multiple vendor servers and employing minimal virtualization to the cost of the company's workloads running on System p 570 (POWER6 processor-based) as well as POWER5+ processor-based servers - all using Advanced POWER Virtualization [APV]. APV is standard on System p5 590 and 595. Other System p servers have the option to add APV except the System p5 185. This cost analysis was performed for financial services, manufacturing and retail example environments with an overall average savings of up to 72% in TCO savings by virtualizing and consolidating on the System p servers. Total Cost of Ownership may not be reduced in each consolidation case. TCO depends on the specific client environment, the existing environments and staff, and the consolidation potential.
