Based on the value, at least $10 billion-$30 billion worth of servers were sitting idle globally at the time of its study. For its part, Anthesis assumed a cost of $3,000 per server, abstracting away infrastructure capital and operating costs. The energy used is substantial, as are the potential savings if zombies are driven out. Not only do they consume power to keep running, but they lead companies to spend more on cooling than they otherwise would have. When it comes to energy, zombies are doubly greedy. Eliminating zombies can reduce costs, green your center, and improve security. The good news is that by identifying zombie servers, you can improve your company in several ways at once.

Sometimes a server contributes some compute or storage, but isn’t utilized fully enough to justify the power expenditure. Sounds straightforward enough, except zombiehood can be a matter of degree-and thus hard to detect. What is a zombie server? A zombie-also known as a comatose server-is commonly understood to be an idle device with no external communications and no visibility, all while guzzling electricity. We’re talking, of course, about zombie servers. Off the beaten track of well-managed hardware lifecycles, they quietly drain energy, compute, and money. But breathing fresh life into otherwise comatose IT equipment isn’t impossible.īuried deep in the recesses of data centers worldwide lurks a silent threat. Improving the utilization of zombie servers in the data center may prove more difficult than first meets the eye.
