We recently purchased HP Lefthand 4500 G2 24TB iSCSI SAN Box.
The Box is configured in RAID6. (and yes, we are going to expand that with
another boxes in near future).
I need to create a 7TB volume at the start, and grow it in near future.
We have a couple of NAS servers (just direct disk connection, not iSCSI)
with XFS filesystems up to ~30TB, but didn't do anything special for
those (just defaults on everything, iirc).
The only problem we had was with filesystems bigger than that, where we
get kernel crashes due to XFS overflowing the stack. Apparently this
may be worse if you NFS-share XFS layered over LVM (more stuff on the
stack, I guess), but I imagine you'd be fine with 7TB.
