Sorry brain dead, I missed the netfinity part.  What server are you running
this in?  If you have the IBM raid manager loaded you can run that within
windows, otherwise you either run the config or open the box up.  Your
server configuration is going to determine how the drives are setup.  If you
get me the model of IBM server you have I can give more information.  I know
the 4M card very well as we have a few of them here.

sorry I missed the other post.
That is your problem, you really, really, really need to get a multi-channel
Raid card, the put the OS, Logs, and store on separate arms.  Until then you
performance is only going to get worse.

No everything is on the same RAID.  We have Blackberry Server edition but
that barely does anything we only 5 people using it.  Also we have Norton AV
but I have shut that off and it still runs hot.  Only the drives though the
processor only runs at like 20%

Are logs and db on same raid 5 set?  Logs should always be on Raid 1 and db
on raid 5 (in an ideal environment).  Logs are sequential I/O's where DB's
are random I/O's.

Are there other applications other than exchange running on the server?  Are
backups taking place at the same time (i.e. peak business hours)?

What is your hard drive config?  What type of SCSI controller are you using?

We have about 850 people on a dual 933 pIII with 2GB of ram.  There is 140GB
of storage on RAID5 and Gigabit Ethernet.  I ran a perfmon on the hard
drives and they run at close to 100% all the time.

yes/no
What is your hardware config?  We have about 750 on one PII 450 Xeon system
and are not having any performance issues at all.  What else is running on
this box.  Need input.

Does anyone else with a fairly large environment (+500 on one Server) have
slowness issues related to hard drive utilization?  By that I mean speed not
actually how large.  Are box runs very slow and the hard drives look peaked.

Thank you,
