Power Efficiency Comparison of Enterprise-Class Blade Servers

Power Efficiency Comparison of Enterprise-Class Blade Servers

Executive Summary Update: April 2011

In August 2010, Dell published a white paper that compared a mainstream Dell blade solution against comparable HP and IBM blade solutions on performance, power, and performance/watt using industry-standard benchmarking methodology. Since that time, HP and IBM have released new Platinum-level efficiency power supplies and updated fans. These configurations were updated accordingly and have been re-tested to compare with the Dell results collected in 2010. The Dell result was not re-tested because the power supplies previously used were already Platinum-level efficiency, and all other components have remained performance and power neutral.

At the time of the new test, Dell also measured the HP BL460c G7 blade servers and compared this data with the G6 server data gathered from the previous test. All of the results fell within the same performance and power level as the previous BL460c G6 results. Thus, it was concluded that the new G7-generation BL460c blade servers do not appreciably impact the performance or power characteristics of the HP blade solution as compared to the G6 results.
