Lowest power dual socket server ever

TechOps Guy: Nate

This was posted a couple of weeks ago but I was on vacation at the time and didn't notice it until a few days ago.

It talks about the latest 4000-series low power chips from AMD running in a dual socket system from ZT Systems.

The numbers are pretty startling. At peak load they measure the power draw at only 126 watts for the system as a whole:

  • Dual processor 6-core Opteron 4164 EE (1.8Ghz per core)
  • 16GB memory (4x4GB DDR3-1333)
  • 128GB SSD

From the blog:

[..] There are four major enhancements to the AMD Opteron™ 4000 Series platform which significantly lower server power consumption:

  1. The AMD Opteron™ 4100 EE Series of processors are the lowest power AMD Opteron processors ever. These processors are rated at 32W ACP, which is 20% lower than AMD’s previous generation 2400 EE Series processors.
  2. AMD Opteron™ 4100 Series processors support 1.35V DDR3 memory, enabling lower server power consumption at load.
  3. The AMD Opteron™ 4000 Series platform uses low-power chipsets. The SR5650 has a maximum TDP of only 13 watts.
  4. AMD Opteron™ 4100 Series processors include new AMD-P power management features, including C1E. C1E is a feature that helps reduce the power consumption of the AMD Opteron™ 4100 Series processor’s integrated memory controller and HyperTransport™ technology links.

[..]
The two lowest power Intel Xeon processor-based servers consume 28% more and 34% more power than the ZT Systems 1253Ra Datacenter Server[..]

Pretty amazing that you can get a dual processor, 12 core(total) system running at less power than some CPUs out there consume by themselves.

I'm sure it will run even at even lower power with rack level DC power and cooling.
