I originally asked about a long term maintenance problem, on how to solve
dependency on one disk server. This isn't a full summary since I haven't
investigated any of the solutions mentioned (as I originally said, it's a
long term stability problem), so I'll just mention potential solutions I have
been told about.

Thanks to the following, with a summary of their comments.

  Two servers connected to a Sparc Storage array, running OpenVision HA
  HA-Solution (www.openvision.com), and Veritas Volume Manager

daves@adnc.com (David Schiffrin)

  Solstice Online Disk Suite 4.0, or www.veritas.com

Nate Itkin <Nate-Itkin@ptdcs2.intel.com>

  Serverguard from Auspex Systems

  "Not an endorsement, just a fact."

Dan Penrod <penrod@wcnewmedia.com>

  www.qualix.com with a storage array (apparently recommended by his Sun
  sales rep).
