Ok, got my raid card, percraid h310. before I flash it to IT mode, I have a question.
The rig is just a fileserver running 8gb ram, core2quad at 3.6ghz running an 240gb ssd for boot and spinning rust x5 in software mdadm raid6 now. with a slow system like this, is there any performance to gain from letting the raid card raid instead of using it as a HBA? Ultimatly I may just run freenas, but I like playing with server stuff in centos. it’s a home storage jobbie, not critical for anything.
Guess I have 3 questions now that I think of it…
Second, boot drive should still run off the motherboard, correct?
Third question, can I create a partition on my ssd for caching, or does the whole drive need to be utilized on the HBA?
ultimate goal is to run in raid 6 and be able to add drives to the data pool. With the card I got I’m stuck with raid 0, 1, 5, 10 because I didn’t realize there wasn’t an advanced key for raid 6 for the h310, so if it would just be better to let the raid card do it’s thing, I would be ok with raid5 for now.
I’m all over the place, I know.
