SAN not NAS, no? And I only wish I could add SAN disk to my AS/400. I know
it doesn't perform exceptionally well on the AS/400, but I have a small
AS/400 (270) and I'd love to wrap it in with all the other storage I have
for W2K and Linux stuff in one single manageable storage network. [1]

[1] Please don't suggest that I put it all in my AS/400, I don't consider
that viable.

If you think about it, IBM is pretty smart. How do you up disk demand? By
preallocating  library space so that each one has to have a surplus of empty
space, and the whole thing has to have a surplus of empty space. Result -
increase disk purchases by two thirds  ( you need 600 GB, you buy 1000 GB,
you have bought 400/600 extra, or 66% increase.)

And when that slows down, invent extra storage pools to do it again.

On their NAS, they implement up to 256 storage areas, so you can mirror or
version on the same system.

Great way to eat up the 4.2 terabytes.
