[ale] syncing disks

[Jeff Hubbs]

Ken -

Maybe what you're after is a distributed file system.  Search for a file
system called Intermezzo and another called Coda.  There is a commercial one
called CentraVision
(http://www.adic.com/US/English/Products/Software/CentraVision/index.html).

For your application, the idea would to be to join two dual-homed servers
via a "backchannel" network (a crossover cable would do) and use a DFS to
store content common to the two systems.  You could accomplish something
similar via NFS and a third server, but the DFS concept would do away with
that.  I believe that CentraVision is such that all shared data would still
be available to one server if the other were down, but you should research
that more fully for the two-server case.
