Raid 1 + jbod !?!??!

I'm setting up a server.

Components:
6x 2TB Harddrives
Chipset: Intel P55 (supports certain kinds of BIOS RAID)

I want to set up a mirror raid. So that 3 drives mirror the other 3 drives.

At first I through RAID 1 could handle a 6 drive mirror automatically, but then I realized it's limited to 2 drives.

So I set up THREE, RAID 1 volumes in the Intel BIOS RAID, and then used Windows Server 2003 to convert each volume to GPT and Dynamic disk.

Using Dynamic Disk with NTFS, I set up JBOD to span the space across all of the 3 volumes, in to one drive letter.

Is this a safe way to do this?

What happens to the JBOD when a drive fails?

It gets what you want, as to how good it is, it varies.

As to the JBOD, if a drive is lost (in your case, a mirrored pair), then the data on that drive is lost. If it is the first drive in the JBOD, then everything is list (as that is where the File allocation table is located).

If just 1 fails the stripe/linear volume will fail but the mirror will be fine since the other side is still ok. If you lose a drive in the other stripe/linear volume at the same time you lose the whole array.
