[zfs-discuss] One dataset per user?

Hi all

We''re working on replacing our current fileserver with something based
on either Solaris or NexentaStor. We have about 200 users with variable needs.
There will also be a few common areas for each department and perhaps a backup
area. I think these should be separated with datasets, for simplicity and
overview, but I''m not sure if it''s a good idea.

I have read people are having problems with lengthy boot times with lots of
datasets. We''re planning to do extensive snapshotting on this system,
so there might be close to a hundred snapshots per dataset, perhaps more. With
200 users and perhaps 10-20 shared department datasets, the number of
filesystems, snapshots included, will be around 20k or more.

Will trying such a setup be betting on help from some god, or is it doable? The
box we''re planning to use will have 48 gigs of memory and about 1TB
L2ARC (shared with SLOG, we just use some slices for that).

Vennlige hilsener / Best regards
