We tested Volume Manager once, but ran into the problem that it has its own
fsck. The consequence was that after a crash we lost all AFS files. And with
the AFS fsck nothing worked. This was more or less in a hurry so I don't know
whether one could have come around the problem.
DiskSuite however works - as it would on normal disks. I have heard that
logged filesystems were problematic, but raid (for which we use it) works
fine. We haven't tested mirrors. Anyway, you don't need DiskSuite to
access the StorageArray disks.

RAID 5 on some of them, normal disks on others.
