OSNews, Generic OSes Yankee Group's second annual Server Operating System Reliability survey polled 700 users from 27 countries worldwide. The latest independent, non-sponsored Web-based survey revealed that all versions of UNIX -- which typically carry very high workloads -- are near bulletproof, achieving 99.999% reliability. IBM's AIX UNIX led all server operating systems for reliability with just over 30 minutes of per server annual downtime but Hewlett-Packard and Sun Microsystems also got high scores.

Downtime average per year may not always be a true test of the OS.

Windows/Linux tend to run on diverse hardware. Some without hotswap drives and such so harware failures could account for the downtime. Vs. the Big Unix systems which have hot swap drives and failover systems, build in at the hardware level.

Also the Userfriendlyness plays a role too, not the actual program reialability. So if it goes down how easy is it for the expert to fix the problem.

I would also like to see some hardware statistics. How does downtime with Solaris compare on x86 vs SPARC? What were the most typical causes of downtime from the sample of operating systems?

Well the downtime encompass the fact that server was down and the time it took to bring it back up. So no user-friendliness excuse... which would be questionable anyhow - I find my system very user-friendly to me ;) If your IT does not know how to fix his server, change IT.

Downtime average per year may or may not be a true test of the OS ... but it is a true test of downtinme average per year.

If you are running a server, and you want it to be reliable, what you want to know about is ... downtime average per year.
