So far the plan is to keep it in one pool for design and
administration simplicity. Why would you want to split up (net) 40TB
into more pools? Seems to me that'll mess up things a bit, having to
split up SSDs for use on different pools, loosing the flexibility of
a common pool etc. Why?
If different groups or areas have different I/O characteristics for
one. If in one case (users) you want responsiveness, you could go with
striped-mirrors. However, if departments have lots of data, it may be
worthwhile to put it on a RAID-Z pool for better storage efficiency.
Just a thought.
