For the sixth year in a row, corporate enterprise users said IBM server hardware delivered the highest levels of reliability/uptime among 14 server hardware and 11 different server hardware virtualization platforms. A 58% majority of IBM servers achieved “five nines” or 99.999% availability – the equivalent of 5.25 minutes of unplanned per server downtime compared to 46% of Hewlett-Packard servers and 40% of Oracle server hardware.
Those are the results of the latest independent ITIC 2014 Global Server Hardware and Server OS Reliability Survey which polled C-level executives and IT managers at over 600 organizations worldwide during March and April 2014.
The survey results showed that the overall reliability HP’s servers increased significantly in 2014 compared to the 2012 and 2013 polls and surpassing the uptime of rival Oracle servers which remained the same or declined slightly compared to prior polls. Cisco Systems, Inc.’s Cisco Unified Computing System (UCS) servers, which appeared for the first time in this year’s ITIC Reliability poll, made a very strong showing, posting uptime equal to or better than HP (depending on the category) and bested only by IBM server reliability. Half – 50% – of Cisco UCS server hardware users said they achieved 99.999% of per server/per annum availability.
