Don't forgo some sort of live data protection -- most likely via
RAID. If these volumes are RW, and you have a storage failure, you're
going to be putting yourself and your users through hell waiting for
stuff to be restored.
If you're not looking for super performance, go for a RAID5ish
solution (or something like a JBOD + raidz using ZFS on Solaris), or
if performance is an issue, hardware or software mirroring is the way
to go.
Storage is cheap -- your time and your users isn't. There are
affordable FC-attached options out there, such as the Apple XRAID*,
and other similar options from smaller vendors. You can probably find
yourself some similar-priced options that do iSCSI from some of the
smaller storage vendors out there.
Also -- avoid the Linux game. Go with Solaris 10 and ZFS. You've got
a solid storage architecture, and a top-of-the-line filesystem, and
you can skip these silly ext3/ext2/reiser/xfs/xvm discussions on the
list ;)

* Apple basically gives these things away to higher-ed, and they offer
pretty damn nice pricing on Qlogic's stackable switches. Talk to your
apple rep. They work great with Solaris too ;)

Hi everyone,
Traditionally, we have used direct-attached scsi disk packs on Sun
Sparc
servers running Solaria 9 for OpenAFS. This has given us the most bang
for the buck. We forgo RAID because we have the backup capabilities
of AFS.
What types of storage technologies are other AFS sites using for their
AFS vicep partitions? We need to figure our future direction for the
next couple of years. Fibre channel seems all the rage, but it's quite
expensive. I'm open to any and all feedback. What works? What doesn't?
What offers the best bang for the buck on an OpenAFS server?
This is for an academic environment that fills both academic and
research needs. Researchers are asking for lots of AFS space (200GB+).
Of course this needs to be backed up as well.
Thanks,
Jason
