Utilizing high-efficiency voltage regulators and an optimized

design, the Intel® Server Board S5500WB delivers

uncompromising performance with up to 30% power

reductions compared to other solutions and savings up

The Intel® SR1690WB Server System supports four 3.5”

drives, a high-efficiency power supply, a PCI Express* x8

(Gen 2) slot, and support for Intel® I/O Expansion Modules.

1 Power benchmark data from SPECpower_ssj2008. http://www.spec.org/specpower/ Measurements were taken on pre-

production systems (January 2009) that were configured with identical memory, processors and hard disk drive, operating

system and JVM. Variables were fan configuration, cooling duct design, fan speed control and power wattage and supply

efficiency rating.

2 PUE = Power Usage Effectiveness. A PUE of 2.0 means that for every 2 watts in at the utility meter, only one watt is

delivered out to the IT load (the server in this case). PUE ratio of 2.0 is the average value across all U.S. data centers.

3 Calculation backup: 32W x 3 years x 365 days x 24 hours/1000 = 1,121 Kilo Watt Hours (KWh). At a PUE of 2.0, that

becomes 2,241 KWh x $0.10/ KWh = $224.

Intel® Server Board S5520UR

An optimized system built around the Intel® Server Board S5500WB saves 32W at the wall

over a typical 1U server such as the Intel® Server System SR1600UR. This equates to total

year life, with electricity cost of $0.10 per KWh, that would amount to over $224 in power
