In the VM blogging world today there was some discussion on which RAID level to use with your virtual environment (Professional VMware Blog & Roger Lund’s IT Blog). This is not an exact science, it really depends on what your doing and what your budget is - and what your storage array supports. If your as fortunate as I am and have a NetApp, you get to use their patented RAID-DP which is their flavor of RAID 6 (ADG) offering double parity - meaning you can sustain a dual disk failure per RAID group and see no performance degradation when repairing the RAID group.
