Well, I have ran a few tests (not truly documented) that booting off
the SAN and booting off of local storage can mean adding an
additional 15-20 users per machine. The pagefile was on the local
storage (internal U160 drives in RAID0).
Now, SAN access speeds are much faster than that of local storage.
Well, the U320 drives are very fast, and with RAID controllers
onboard CACHE increasing in sizes (256MB to 1GB so far), they are
competing with RAID Groups on a SAN.
Solid state drives are WAY to much in cost to justify that type of
expenditure, IMHO. We tested the TIGI drives here, and found that
the concept worked. But, for $5,000 per GB of Solid State, that
didn't make much sense. Well, for a TS server anyways. A high end
DB server, or Exchange/groupware, yes.
