Cost of power based on DOE estimates of commercial cost for energy. Cooling assumed to equal ½ the cost of power. DOE estimate for Jan 2009 was $.1003 per KWh.

• Maintenance prices based on 3-year 24X7 warranty upgrade for Power 570.
• Maintenance price based on 3rd party HW only with telephone support for the E6900.
• Assumes that licenses are transferred from E6900 to new systems and that the only cost of middleware is support and subscriptions.
• SysAdmin cost estimated at one SysAdmin for every 10 systems at a cost of $100,000 per year.
• Downtime calculated based on lost productivity of end users. Assumptions were 5,000 hours of annual operation with an average 500 on-line users, average user salary of $50,000 for 1600 hours of work (52 weeks –vacation, holidays, sick time and training) with availability for the Power 550 of 99.9% and availability of the Sun systems at 99.8%.

• The number of IBM BladeCenter JS22 servers required to replace 180 Sun Fire V490 was calculated based on SPECint_rate2006 results and estimated utilization rates for non-virtualized and virtualized environments.
• The V490 SPECint_rate2006 result is for a 2.1GHz system with 4 chips and 2 cores per chip. It has a result of 78.0. The V490 result can be found at www.spec.org. It is current as of October 23, 2007. The JS22 result for the same benchmark is for a 4.0GHz system with 2 chips and 2 cores per chip. It has a result of 84.7. That result was submitted on November 6, 2007. It will also be posted on www.spec.org (link resides outside of ibm.com).
• The cumulative capacity of these servers is estimated to be the SPECint_rate2006 result for one server multiplied by the number of servers. The calculation shows the cumulative capacity of the 56 JS22 servers is > than the cumulative capacity of the 60 V490 servers at equal utilization. A virtualization factor of 3X was applied to the virtualization scenario using utilizations derived from studies conducted by Alinean available at http://www.ibm.com/services/us/cio/optimize/opt_wp_ibm_systemp.pdf (PDF, 74.41KB). That is the utilization rate for the non-virtualized capacity of the V490 is estimated to be 20% and the utilization rate for the virtualized capacity of the JS22 is estimated to be 60%. The used V490 capacity is therefore estimated as 180 *78 * 20% = 2,808. The JS22 used capacity is estimated as 56 * 84.7 * 60% = 2,845.92. Therefore the cumulative capacity of the 56 JS22 servers at 60% is > than the cumulative capacity of the 180 V490 servers at 20% utilization.
