1.4 Energy efficiency
We put extensive engineering effort into keeping your energy bills low - from high-efficiency
power supplies and fans to lower-draw processors, memory, and SSDs. We strive to reduce
the power consumed by the systems to the extent that we include altimeters, which are
capable of measuring the density of the atmosphere in the servers and then adjusting the fan
speeds accordingly for optimal cooling efficiency.
Technologies, such as these altimeters, along with the Intel Xeon 7500/6500 series
processors that intelligently adjust their voltage and frequency, help take costs out of IT:
򐂰
95W 8-core processors use 27% less energy than 130W processors.
򐂰 1.5V DDR3 DIMMs consume 10-15% less energy than the DDR2 DIMMs that were used
in older servers.
򐂰
SSDs consume up to 80% less energy than 2.5-inch HDDs and up to 88% less energy
than 3.5-inch HDDs.
