Sounds like three SM51 modules to me.

1.2 GB.. those would be ST31200N drives, then? Bad news, if you've got
drives to replace them, I'd say do it. Every time we power off one of our
few remaining SSA110s (which are full of those disks), we have about a 50%
chance that one or more disks will never spin back up again.

I HATE those disks.

Still not too bad.

Yes, usually machines with that much RAM are solving problems which
require lots and lots and lots of memory. (:

On the Suns I manage, we do double physical RAM unless some beancounter
horribly overspecified the system on the PO. Never do less than 125%
physical, or else you can run into trouble with savecore if the machine
ever crashes. The biggest system I've ever managed had 48 GB RAM and 250
GB or so of swap---and was appropriately sized for the task. That was in
the data warehouse at Amazon.com. I think my NDA is up by now and they've
probably changed things enough that I can talk about it.

ok
