Compare UNIX Servers

1. Competitive benchmark results reflect results published as of January 1, 2010. Each result is the best performing result for the benchmark. The benchmark results and detail can be found at the Dare to Compare Performance Web page. The SPECint_rate2006 results can also be found at www.spec.org (link resides outside of ibm.com).

Performance/WATT is calculated by dividing the performance from the tables on the Dare to Compare Performance webpage by the recommended maximum power usage for site planning. This defines the requirement for the power infrastructure. Actual power used by the systems will be less than this value for all of the systems. For Power Systems, this information is available in the respective site planning guides for each system available through www.ibm.com. For HP systems, this information is contained in the QuickSpecs for each system available through www.hp.com (link resides outside of ibm.com). For Sun systems, this information is available through the respective Site Planning Guides available through www.sun.com (link resides outside of ibm.com). The maximum power for blades is based on the maximum power requirement for a fully loaded blade chassis divided by the number of blades the chassis can hold. All data is from those documents and is current as of January 1, 2010.

The maximum power requirement for each system is:
