We have a server where I work that uses some card called Rocketport
Raid. I think it was made by adaptec. I believe that it is a true
hardware raid, but it very well may be just a more expensive fakeraid.
I have no idea if it is supported under linux, but there is a good
chance it is not.
Ironically, a few weeks ago this raid card shat itself and somehow hosed
up the raid configuration such that it believed that two of the 4 disks
in the raid5 were a part of one array, and the other 2 were part of a
completely different array ( with the same name oddly ), so it was
unable to access the array. We ended up having to rebuild it and
restore from backups.
Because of that, I'll trust the open source md more than proprietary
