I've never had the pleasure to actually see one of those, but for
example IBM sells their storage servers, which can hold up to 224 SCSI
drives. The largest drive now s 146G, so that gives you 32T. With some
RAIDing you are looking at 16T of storage in one box (huge it may
be--actually occupies whole 90U rack). You can use more of them I guess,
since version 8 has tablespaces. Be prepared to spend some half a mil
for this beast and we are talking US dollars here (listing price is
$760k, but who would shop for listing prices, eh?). Beware, nuclear
powerplant not included. If you get one of those, let us know how
Postgres hums on it :)
