Use low voltage version of processor to save energy for enterprise

Does your IT system cost more and more? Are you at pains to reduce power and conserve energy? We will from the chip, components, systems, software and even data centers, and many other levels, from a number of points of view, sorted out a series of practical it energy-saving coup, I believe there is always a trick for you!

According to statistics, the processor in the server power distribution accounted for 30% of the proportion, can be said to be the server system "Barroth". In this respect, including Intel, AMD and other mainstream chip manufacturers have introduced with the normal processor, consistent performance, lower power consumption, a slightly higher price of the low voltage version of the processor.

Intel, for example, is selling the marketed low voltage version of 50W 45 nm 5400, which is more expensive than the equivalent of normal Xeon 5400, but can provide lower power consumption while maintaining consistent performance.

In general, the low voltage version of the Xeon 5400 than the ordinary CPU to save 30 watts of electricity, reduce power consumption of 35%. This may not be a big thing for a server, but the amount of energy saved in a single year is considerable for the number of servers up to hundreds of or even thousands of data centers.

AMD, in May this year also launched the average power consumption (ACP) only 55 watts of Low-power four-core AMD Hao long true He (highly efficient: energy efficient processor, there will be 2300 and 83,002 series for 2, 4, and 8-way rack and blade servers.

In addition, it is worth noting that, because the CPU in the sleep and shutdown state of idle power does not produce any production value, so the chip manufacturers have been trying to reduce this power expenditure. In the case of Xeon 5400, the idle power is only 16 watts, while the previous generation of 65 nm products is about 30 watts.
