I'm looking at building a high bandwidth file server to store video for
editing, as an alternative to buying a $30,000 hardware RAID and spending $2000
per seat on fibrechannel and specialized SAN drive software.
Uncompressed HD runs around 1.2 to 4 gigabits per second, putting it in 10
gigabit
Thanks for the detailed information. When you get the patch, I'd love to hear
if it fixes the problems you're having. From my understanding, a working
prefetch would keep video playback from stuttering whenever the drive head
moves — is this right?

I was thinking of custom building a server, which I think I can do for around
$10,000 of hardware (using 45 SATA drives and a custom enclosure), and putting
OpenSolaris on it. It's a bit of a risk compared to buying a $30,000 server,
but would be a fun experiment.

Bob, thanks for the tips. Before building a custom solution I want to do my due
diligence and make sure that, for every part that can go bad, I've got a backup
ready to be swapped in at a moment's notice. But I am seriously considering the
alternative as well, paying more to get something with a
Marc,
Thanks for the tips! I was looking at building a smaller scale version of it
first with maybe 8 1.5 TB drives, but I like your idea better. I'd probably use
1.5 TB drives since the cost per gigabyte is about the same now.

Also, one of those drives will need to be the boot drive. (Even if it's
possible I don't want to boot from the data dive, need to keep it focused on
video storage.) So it'll end up being 11 drives in the raid-z.
