By 2009, the server consolidation effort had resulted in consolidating 1,250 servers down to only 250 while consuming 60% less space, 70% less power, and 70% less cooling. These results came from the first two server virtualization tactics. Tactic 1 (virtualizing new, dedicated application environments) helped EMC to avoid buying 640 physical servers through December 2008. CPU utilization was not optimized, with the P2V consolidation ratio remaining at only 5:1, because servers were still dedicated to specific applications. Tactic 2 (replacing EOSL hardware with shared, virtualized servers) enabled EMC to decommission 424 physical servers and replace them with only 62. | Basel Committee on Banking Supervision External audit quality and banking supervision December 2008 Requests for copies of publications or for additions changes to the mailing list should be sent to Bank for International Settlements Press Communications CH-4002 Basel Switzerland E-mail publications@bis.org Fax 41 61 280 9100 and 41 61 280 8100 Bank for International Settlements 2005.
