and others that are still pouring in.

I received a link that has a nice summary of DiskSuite vs VxVM at:
http://www.eng.auburn.edu/pub/mail-lists/ssastuff/sdsvxvm.html

There's a general consensus that DiskSuite is well adapted to very simple
fairly static situations, like mirroring of system disks. As soon as good
recovery and better flexibility is needed, VxVM is better. It also looks
like VxVM is faster for software RAID-5.

VxFS boasts a more efficient design when dealing with huge amount of data
and huge number of files. The journaling might also be more robust. VxFS
also supports bigger filesystem sizes, and supports shrinking (but who's
really in need of shrinking a filesystem ? Not me at least).

Given the fact that the ScholarPAC price of both VxFS and VxVM is low,
we'll go with them.

Thanks for all the help!
