James Hamilton continues his focus on energy efficiency at Amazon after leaving Microsoft.
Earlier today I presented Where Does the Power Go and What to do About it at the Western Washington Chapter of AFCOM. I basically presented the work I wrote up in the CIDR paper: The Case for Low-Cost, Low-Power Servers.
The slides are at: JamesHamilton_AFCOM2009.pdf (1.22 MB).
The general thesis of the talk is that improving data center efficiency by a factor of 4 to 5 is well within reach without substantial innovation or design risk.
