Thanks. "Procurement for Asia datacenter has
started" is big news! Is
energy efficiency a criterion for the product/supplier selection?
(This needs not be something very complicated. For instance Dell asks a
small surcharge if you want a more efficient PSU, IIRC. <
We buy servers from two standard vendors (Dell and HP), and select the most
energy-efficient components (including PSUs) available for the task - not
only because it's better for the environment, but also because it allows us
to achieve higher rack density (more servers within the same space) and
therefore also saves costs over time.
These server configurations have been carefully sized, selected and
tested/measured in practice with actual work loads to provide the most
optimal usage of resources. For example, through consolidation and
optimization of cache clusters onto fewer, but somewhat higher capacity new
servers we've reduced the amount of equipment and power required to
approximately 60%, also shrinking data center space, supportive
infrastructure and management needs in the process.
