Can someone decode the following terms?

RAID levels  - RAID 0, 10, 50, MP**
I know what RAID 0, 10, 50 means but not MP**?

Also, RAID 5 --- 2:1 and 8:1?
RAID 6 Data to parity ratios 6:2, 14:2?

RAID MP is a patented technology by 3PAR, where MP stands for Multi Parity and is somewhat similar to RAID6.

The 'm:n' shows the number of disks that are being used for data : parity, which means 2 disks for data and one for parity in the first case. Though I don know why one would explicitly mention 8:1, except 9 disks is the max the controller could handle.

RAID6 works similar like RAID5, but uses 2 disks for parity. In a RAID6 scenario two disks may crash and it would still be up and running. A normal RAID6 should be able to run on a 2:2 setup, though.
