Thinking about buying the Powervault MD3000 SAS array with 15 15k
300GB disks for use as a postgres tablespace. Is anyone using these
(or other LSI/Engenio rebadge jobs?). I'm interested in hearing about
performance of the array, and problems (if any) with Dell's SAS HBA
that comes bundled. Also interested in performance of the maximum
config of an MD3000 with two MD1000 shelves.

Might want to check out the HP MSA70 arrays. I've had better luck with them
and you can get 25 drives in a smaller rack unit size. I had a bad
experience with the MD3000 and now only buy MD1000's with Perc 6/e when I
buy Dell.
Good luck!

I can second this. The MSA 70 is a great unit for the money.

Thank you both. The MSA 70 looks like an ordinary disk shelf. What
controllers do you use? Or, do you just go with a software RAID?

In a Dell box I use a Perc 6/E with a SAS to Mini SAS cable.

There was a fairly long recent thread discussing the Dell Perc 6 controller starting here:
http://archives.postgresql.org/pgsql-performance/2008-03/msg00264.php
and one relevant follow-up regarding the MD1000 box:
http://archives.postgresql.org/pgsql-performance/2008-03/msg00280.php
(Unfortunately, the Postgres web archive does a terrible job formatting plain-old-text messages, it doesn't seem to know that it should wrap paragraphs, so some of these are pretty hard to read as web pages.)
