Jesse, what advantage does having a 16 drive RAID array give you? I'm in no way a RAID expert and don't understand the business need for a 16 drive array.

Thanks!

Bob

raid isn't cheap.  Promise and BCM aren't true hardware raid last
time I checked, you're still using your own CPU to calculate raid
operations.  Especially harmfull when doing raid 5.

Yes, they aren't RAID boards. But Linux_soft_raid is cheaper, more secure and flexible and not slower. I don't see any case where is the best a low end RAID board than Linux_soft_raid.


For 2 drive stuff, sure maybe. But we deal with 4/8/12/16 drive chassis, all on 3ware stuff. I don't think software raid can handle those situations. Especially not with remote web configurations, alerts (included, not build your own), etc...

Software raid has it's place, and it's cheap, but the Original Poster asked for a hardware solution. The only solution I would consider is a 3ware solution.
