Users who decommission equipment quantify savings for Uptime Institute
The Uptime Institute estimates that 20% of all racked IT equipment has no earthly function other than to warm the planet. But for data centers that do manage to unplug equipment, the savings are significant.
To draw attention to the issue of what are sometimes called “ghost servers,” Uptime held a contest, inviting data center managers to submit their own efficiency efforts. The results are impressive.
Barclays, the top performer in Uptime’s ranking, removed 9,124 physical servers last year. Those servers, in total, consumed 2.5 megawatts (MW) of power and could fill 588 server racks. The company’s power bill would be $4.5 million higher if the systems were still running.
Moreover, Barclays saved $1.3 million on legacy hardware maintenance costs and freed up more than 20,000 network ports and 3,000 SAN ports.
