Let me know if you find something in software.  Compaq offers some hardware
junk, and of course there is clustering.  So far I've only met with SCSI device
drivers which work over the network (non-fire-wire) by a company from Israel.

Check for "Octopus" at www.sunbelt-software.com or www.sunbelt.co.uk
We don't use it, but from the ads it seems to address your problem.

Mark -

This is what Failover Clustering is all about.
Look into WolfPack from NT and Digital Clustering from DEC.

Having experience with both Octopus and Vinca Standby Server for NT, I
would recommend the Vinca Standby Server for NT.  My experiences with
Octopus have never been fun.  During our last attempted install and setup
of the Octopus product we had so many problems that the Octopus engineers
came onsite 3 times.  After 3 visits from their engineers the Octopus
software still did not function properly.  I then brought in the Vinca
Standby Server for NT and had everything configured and working correctly
in under 45 minutes.  The call is ultimately yours, but I recommend Vinca
highly!

Check out also FirstWatch from Veritas http://www.veritas.com .  It does not "replicate the system" (mirroring?) but
provides a hot standby solution that will failover in a couple of seconds.  Agents are provided and can be developed to
make decisions about when a failover should occur (a table in a database becoming corrupt or a service stopping).  Th
product is fairly easy to install and IMHO very reliable.

It's incorporated in NT 5, beta may be available.
