It really depends on what the load is and how much flexibility you want. Parity calculations will always be faster using a dedicated controller, so consider that when you deploy a software RAID 5/6. MD itself is very reliable, I have no problem trusting it with my data, with the added bonus that you have the opportunity to fix it yourself. Sometimes vendors can be slow to address HW RAID firmware bugs. You don't have to worry so much about the "RAID metadata problem" because you're going with an OEM. > > I have been reading about this but still I am undecided. If you have time do a little benchmarking, expect that the HW RAID will win out in write intensive loads. The tradeoff then becomes one of management and instrumentation. Openmanage + SNMP traps and you're basically done with monitoring your RAID. With MD there will be a little more work involved and perhaps require integration with something like nagios to get the same effect as what openmanage offers. Then again, going with an opensource stack offers all sorts of possibilities.
