Abstract - Comatose servers, aged servers abandoned by application owners and users, but still racked and running and eating up energy costs, are a major problem in data centers today. Unless you have a rigorous decommissioning comatose server program, it is estimated that between 15%-30% of the equipment in your data center is comatose. We have created this Starter Kit to help you start your own decommissioning program. Included in the downloadable kit is a calculator that will help you evaluate potential cost savings from shutting down comatose servers in your data center, A Guide to Decommissioning Comatose Servers, a sample comatose server audit form and labels to help track and identify servers no longer performing.
