Quite awhile ago, long before Cassatt revamped its product line to feature its power savings features, I blogged about how Cassatt's Active Response software could do that (see old blog here). At that time, I assembled a simple power usage calculator to give an idea of how much you might be spending on server power. Since that time, our technical marketing dept. has put together a much more comprehensive power savings calculator. Take a look and run some of the numbers for yourself. In today's go-green environment, it's pretty interesting to see how much power you consume and how much it costs to run your data center (and, oh by the way, I think Cassatt can help :-).
