Saturday data center tidbits.

First up on the reading list this morning is an article about 4 ways to save energy in the legacy data center. Not a bad read, but the idea that virtualizing servers doesn’t save more than 15% sounds a bit silly to me. If you virtualize 8 servers operating at 10% utilization on to 1 server of the same configuration utilizing 80%, you’re certainly gaining far more than 15%. If you virtualize those 8 servers on to a single server that’s much bigger, then you don’t save as much obviously, but you have the capacity to add more virtual servers. If you don’t expect to need to grow your capacity, right size your virtual server platform.
