But it's early (for me), and I can't remember the answer here.
I'm sizing an Oracle database appliance. I'd like to get one of the
F20 96GB flash accellerators to play with, but I can't imagine I'd be
using the whole thing for ZIL. The DB is likely to be a couple TB in size.
Couple of questions:
(a) since everything is going to be zvols, and I'm going to be doing
lots of sync writes to them, I'm thinking that allocating around a dozen
GB of the F20's flash would be useful. :-)
(b) can zvols still make use of an L2ARC device for their pool? I'm
assuming so, since it's both block and metadata that get stored there.
I'm considering adding a couple of very large SSDs to I might be able to
cache most of my DB in the L2ARC, if that works.
