Reports on the power consumption of the Sun Fire X4450 Server running VMmark from two sources show that the server's eco-efficiency comes in at an impressive level. AnandTech reports the Sun Fire X4450 delivers one of the best scores among all 16-core results -- 12.23 @ 8 tiles and an average power consumption of only 830W, measured during the steady state of the benchmark. That means the Sun Fire X4450 is at least 60% more power efficient than, for example, the Dell PowerEdge R900 and HP ProLiant DL 580 G5 systems, and at less than half the footprint of those two units.

A second report on results of the benchmark testing of the Sun Fire X4450 comes from the blog of BM Seer. He notes that Sun used the 64GB configuration in the benchmark, which tested the IBM x3850 M2, the Dell PE R900 and the HP DL 580 G5. Seer reports that the Sun wattage measured on two hours benchmark steady state: Watts: min=788watt, max=850watts, avg=830watts.

BM Seer also comments on the fallacy of mixing SPEC and non-SPEC results in reporting power consumption. In this context, he recommends that, "...SPEC require better disclosure of information and clearly show effects of CPU GHz and memory size. Memory size makes a huge difference in watts. Again I plead to add power measurements and power-performance metrics to all performance benchmarks at full utilization." [...read more...]
