RAID 5 Question for Mac Pro
Hi,
I am a noob to mac and our dept just purchased a mac pro server with os x server (snow lep) running on it.
I am trying to setup a Raid 5 configuration. I open the disk utility and I can see 4x 2 TB drives.
When I add those 4 drives to make a Raid 5 config, the only options I see under RAID TYPE is:
-Mirrored Raid Set
-Striped Raid Set
-Concatenated Disk Set
Should I conclude that my Raid card is not capable of Raid 5 or is there some mysterious Mac setting I am overlooking :)
Remember I am a Mac noob. Thanks.

I went ahead and created a "Striped Raid Set" using only 3 drives. If each this truly a Raid 5 wouldn't I expect to see the size of the Volume to be 4 TB? Each drive is 2 TB. After the Raid set was created I noticed that the size is 6TB. Is this really Raid 5?
RAID5 is not supported by OS X software. there is an extra RAID card you must buy from Apple that does it.
RAID 5 on mac requires a RAID card.

There is a seperate utility for the raid. I thought it would be in the disk utility but I was wrong.
I was going to use raid 1 but creating or breaking the mirror requires wiping the drives. I didn't like that.
