This
is definitely a documented issue. We worked with Dell on this. The
reason other people aren't having this problem is because it only shows up under
a heavy I/O load. Our databases average roughly 40gb. We were hit
hard by this.

Subject: Dell problemsAnyon ever see this.Hello all,
I've got what may be a unique problem. It appears that the Dell PERC RAID
controller (various revisions, versions, etc) is crashing Exchange 5.5 SP4
on a fairly regular basis. Exchange is left in a corrupt state and must be
restored from a backup. This is our platform:
Win2k Server SP1
Dell 4400 PowerEdge Server
Perc 3/3Di RAID controller with writeback caching turned *OFF*
Exchange 5.5 SP4
About 120 users and an IS of 23 GB.
2 Containers on the RAID, one RAID 5 (holds the priv and pub.ebd) and the
other a simple 1-disk container (hold the logfiles)
This is the root Exchange site for our company; each office (about 60) has a
local Exchange 5.5 installation.
For about a year, we've had problems with the RAID and Exchange. On multiple
occasions we've experienced a failure in the RAID which caused the RAID to
fail-out a disk drive (although subsequent diag shows no disk problems).
Exchange has become corrupt consistently when this happened. Also, when the
RAID controller issues a "Battery Charge OK" message (it is a trickle-charge
cache battery), Exchange often hiccups with a trashed log file or corrupt
database.
We've reported this problem to Dell tech support repeatedly. Over the year,
we've been given new RAID cards, SCSI controllers, disk drives,
motherboards, as well as a totally new server. The problem keeps occurring,
and now we're looking at mirroring software in order to recover more
quickly. But we have no real solution.
Question #1: is this a unique situation, or are others experiencing problems
such as this?
Questrion #2: is the size of our IS a problem (23 GB), since the start of
these problems seems to have followed on the heels of the growth of IS?
Any feedback on this would be much appreciated, as it is driving us batty.
