Have you looked at using Oracle ASM instead of or with ZFS? Recent Sun docs
concerning the F5100 seem to recommend a hybrid of both.
If you don't go that route, generally you should separate redo logs from actual
data so they don't compete for I/O, since a redo switch lagging hangs the

It seems to have good customer ratings so far at newegg.com, but currently
there are only 13 reviews so it's a bit early to tell if it's reliable.
Has anyone tried this model with ZFS?
