I've been 1000% satisfied with Partners Data for my RAID systems. I
connect to the host boxes with a fibre channel. They've gone above
and beyond expectations for supporting my FreeBSD systems. I don't
know if/how they support postgres as I never asked for that help.
Their prices are excellent, too.
As for your plan to hook up Dell storage to a 320-2x card, the last
time I did that, the lsi card complained that one of the drives in the
14-disk chassis was down. Identical on two different arrays I had.
Dell swapped nearly every single part, yet the LSI card still
complained. I had to drop the drives to U160 speed to get it to even
recognize all the drives.
I hooked up the same arrays to Adaptec controllers, and they seemed to
not mind the array so much, but would cause random failures
(catastrophic failures resulting in loss of all data) on occassion
until I dropped the disks to U160 speed. Dell swears up and down
that their devices work at U320, but the two arrays I got from them,
which were identical twins, both clearly did not work at U320 properly.
It is these Dell arrays that I replaced with the Partners Data units
last year. The dell boxes still have a year of warrantee on them...
anyone interested in buying them from me, please make an offer :-)
