Anyone with ATTO R380 SAS/SATA RAID card? at DVinfo.net

Hi, I've been trying to make things work with ATTO R380 for about several months now, but pretty much always ending up loosing the volume at the end.
It always work good for awhile, but all of a sudden, loose the volume and a couple of the drives get degraded or fail (from 8 drive raid).

I figured out that, first, the infiniband cable can't be long, although they say 3 meter cable should work, but I had less chances to make things work with 3 meter cable, I had to turn off the 3Gflop mode on the drive to make things work.

Secondly, the R380 itself runs really hot, you can't insert it on the top slot of Mac Pro if you have third and fourth drives install in the internal drive bays. When things get overheated, I would have a couple of degraded or failed drives and I won't be able to save the volume.

Has anyone had good or bad experience with this board?

I checked for more information and found some posts in the apple forum that discussed about its heat problem.

Mac Pro's default fan setting is not enough to cool the R380 board. You would notice other things like the internal hard drives run really hot, too.

smcFanControl application was mentioned by ATTO to set the fan setting at higher rpm. I experimented and found that setting at 1,000 rpm does not add so much running noise but still cools inside of computer at 40 degree C even duplicating large amount of files that takes hours (which means read and write on the R380 card both ways, thus a lot of traffic).
