Probably not, my box has 10 drives and two very thirsty FX74 processors
and it draws 450W max.
At 1500W, I'd be more concerned about power bills and cooling than the UPS!
Yeah - good point, but I need my TV! - or so I tell my wife so I can
play with all this gear :-X
Cheers,

This should, of course, set off one's common-sense alert.

Well, noticeable again comes back to your workflow. As you point out
to Richard, it's (theoretically) 2x IOPS difference, which can be very
significant for some people.
Yeah, but my point is if it would be noticeable

Hey Adam,
My first posting contained my use-cases, but I'd say that video
recording/serving will dominate the disk utilization - thats why I'm
pushing for 4 striped sets of RAIDZ2 - I think that it would be all
around goodness
It sounds good, that way, but (in theory), you'll see random
Nit: small, random read I/O may suffer. Large random read or any random
write workloads should be ok.
Given that video-serving is all sequential-read, is it correct that
that raidz2, specifically 4(4+2), would be just fine?
For 24 data disks there are enough combinations that it is not
Sorry, but looking again at the RMP page, I see that the chassis I
recommended is actually different than the one we have. I can't find
this chassis only online, but here's what we bought:

Probably a 64 bit dual core with 4GB of (ECC) RAM would be a good
starting point.
Agreed.
So I was completely out of a the ball-park - I hope the ZFS Wiki can be
updated to contain some sensible hardware-sizing information...

I will only comment on the chassis, as this is made by AIC (short for
American Industrial Computer), and I have three of these in service at
my work. These chassis are quite well made, but I have experienced

Indeed! - though my wife and kids don't seem to appreciate it so much ;)

Getting there - can anybody clue me into how much CPU/Mem ZFS needs?
I have an old 1.2Ghz with 1Gb of mem laying around - would it be sufficient?
It'll use as much memory as you can spare and it has a strong preference
for 64 bit systems. Considering how much you
