Hi Luke

Glad you're having good experinces with PVFS so far.  

I don't think there is anything close to a
consensus for the best SAN hardware to use for high-availablity PVFS.
We're getting some hardware in-house to experiment with in preparation
for some larger deployments.  We might have some good insight to offer
you after we get our hands dirty.  

I'm only a little familiar with the hardware out there these days, but
I would ensure that a LUN can see all disks for starters.  After that,
it's "only" a matter of tuning.
