When evaluating a server, performance and power consumption are two key factors that organizations should take into account. Perhaps most important, however, is the efficiency with which the server can translate energy into useful work performed in the data center?a factor captured by the key metric of performance per watt. Maximizing performance per watt can lead to significant improvements in IT productivity without increasing power consumption.In January 2009, Principled Technologies performed Standard Performance Evaluation Corporation (SPEC) SPECjbb2005 tests commissioned by Dell to compare the performance and power consumption of three AMD Opteron? processor?based blade servers running the Sun Solaris 10 OS: the Dell? PowerEdge? M905 blade server, HP ProLiant BL685c G5 blade server, and IBM® BladeCenter LS42 blade server. In these tests, the Dell server produced the highest peak performance of the three tested systems, providing 4.3 percent higher performance than the HP server and 5.5 percent higher performance than the IBM server. And because the Dell server also used the least amount of power of the three tested systems, it also delivered significantly higher performance per watt?37.6 percent higher than the HP server and 46.7 percent higher than the IBM server.Optimizing energy use can be critical to controlling operational costs in enterprise data centers. As these Principled Technologies tests demonstrate, Dell PowerEdge blade servers are designed to offer high performance while minimizing power consumption?providing the foundation of an effective and comprehensive strategy for data center efficiency.
