For the fifth year in a row, IBM servers delivered the highest levels of reliability and uptime among 14 server platforms.
Those are the results of the latest independent ITIC 2013 Global Server Hardware and Server OS Reliability Survey which polled C-level executives and IT managers at over 550 organizations worldwide from August 2012 through January 2013.
Among the high-end mainframe class systems, both the IBM System z and the Stratus Technologies’ ftServer 6310 delivered the highest inherent reliability: both had no instances – 0% – of the most severe Tier 3 outages lasting four hours or more of duration. Among the mainstream “work horse” servers, IBM’s Power Systems recorded the least amount of unplanned downtime, approximately 13 minutes per server/per year. By contrast, some 6 percent of organizations using Oracle (formerly Sun Microsystems) x86-based servers experienced of over four (4) hours of per server/per annum downtime. This was the highest percentage of lengthy Tier 3 server outages among the 14 platforms surveyed.
