Hi,

We've been having a hard time deciding which RAID solution to go with, and
are currently torn between the DPT controller and a CMD CRD-5440.

I'm kind of leaning towards the CMD, as I'm not quite sure the DPT will be
trouble-free yet.  Today our DPT test box just started beeping on a reboot 
for no apparent reason.  I didn't get a chance to boot DOS to see what was
up, and I started wondering how long it would beep like that at a colo
with no one to hear it...

So my questions are:

The CMD provides a serial interface for setup/troubleshooting.  I assume
we could write some simple script to "look" at it every now and again and
verify that there are no failed drives.  Has anyone else done this?  How
do most people detect a failure when the machine is at a remote location?

Is $1800-ish (U.S. $'s) a good price?

Has anyone run into problems with the CMD?  Is the firmware generally
stable?

How do the DPT and CMD compare for speed?  We're primarily looking for
RAID 1, and a few machines will use RAID 5.

Any additional comments/horror-stories welcome...

Thanks,

Charles
