The MD3000 (and MD32xx) family systems will only support drives with licensed/certified Dell firmware.

I suggest you return your drives and call your Dell salesrep and buy drives that are specifically (certified and carry the right (licensed) firmware) for the MD3000.

The point of RAID is 'Redundant Array of Inexpensive Drives'. Inexpensive being the key word. If one fails who cares. It was cheap and you already had redundancy built in because you bought a bunch of them and most likely have hot spares standing by. With Dell's pricing RAID is not inexpensive.

Dev Mgr · Answer

Inexpensive is a relative term. Drives with little to no chance of failing (MTBF over 10 million hours or so) would probably cost 5 to 10 times as much as the Dell drives, making the Dell drives still inexpensive.

Also, SAN reliability outweighs the cost of a drive by far. Raid controller firmwares and harddrive firmwares for SANs (Dell, but also HP, IBM, EMC, SUN, etc) get designed for eachother at a fairly decent cost of development. The company that writes the firmware wants to get these development costs back somehow (i.e. by selling the drives for (a lot) more than retail drives). One alternative would be to charge for the firmware, but this would either make the firmware really expensive (how can a company verify if you're applying the firmware to just 1 drive or to 50 drives, so they'd charge for an expected average and those just needing it for 1 drive would have to pay a whole lot), or have some kind of system to have the vendor apply the firmware to retail drives for a price. Another alternative would be to raise the initial price of the array by quite a bit.

Those SAN solutions that don't require certified drives, you end up seeing more Google hits about people having issues with certain drives dropping (even with raid-firmwared drives) and other issues. Not that those solutions are lesser by any means, but because the raid controller to drive communication has to be a lot more generic, raid controllers end up missing out on details that could tell the admin what may be going on.

Also, RAID nowadays actually is more commonly a "Redundant Array of Independent Disks" (source: wikipedia).

Hmm   aye on the inexpensive being a relative term...   Price out drives from other san lines.   :)    The PV series is still the cheapest san storage out there to add drives to.
