I am investigating a SQL server performance issue where the system
operates well at times and poorly at others. This SQL server is
connected to a SAN where I believe the issue lies. I have started some
testing using the SQLIOSimx86 utility from Microsoft with the
application stopped. My initial results show that there are quite a
few errors that indicate

"IO requests are outstanding for more than 15 sec."

I am next going to look @ the IO system as a whole (bios,driver
version)

Any thoughts? I can't seem to find any documentation regarding this
and whether this is acceptable.

Thanks,

Scott
