It is very satisfying to know that the platform I have been recommending to our clients (usually AIX on Power Blades (JS12 or JS22) is the most reliable platform* out there.
For the second year in a row, IBM AIX UNIX running on the Power or “P” series servers, scored the highest reliability ratings among 15 different server operating system platforms – including Linux, Mac OS X, UNIX and Windows.
Those are the results of the ITIC 2009 Global Server Hardware and Server OS Reliability Survey which polled C-level executives and IT managers at 400 corporations from 20 countries worldwide. The results indicate that the IBM AIX operating system whether running on Big Blue’s Power servers (System p5s) is the clear winner, offering rock solid reliability. The IBM servers running AIX consistently score at least 99.99% or just 15 minutes of unplanned per server, per annum downtime.
*Distributed platforms at least.
