Determining how much energy a server consumes can be a fine art. Learn how to get started using our Server Energy Consumption Calculator.

Buying a server is a long-term investment. It’s not only the cost of hardware and software that matter, but the power costs to make that server consistently available to users. Add in a fleet of servers in a data center operating 24 hours a day, and power costs quickly add up.

Use the our toolkit to calculate server power usage. It includes a spreadsheet which can help provide an average baseline of what you can expect to pay in energy costs for old/existing servers versus new servers. The list includes many common servers available now, with the list of vendors based both on market share, with IBM, HP and Dell among those included, as well as Oracle, Fujitsu and Cisco.
