Draid6

Distributed array properties. These arrays, which can contain 4 - 128 drives, also contain rebuild areas that are used to maintain redundancy after a drive fails. As a result, the distributed configuration dramatically reduces rebuild times and decreases the exposure volumes have to the extra load of recovering redundancy. Using mismatched drives in RAIDZ2 or DRAID6. Hey guys, I'm new-ish to this arena of non-traditional RAID and trying to understand how capacities vary. I've spent quite a while on the Googles and Youtubes trying to figure this out and am stumped.

I am basically building the spec of the new server and IBM threw this DRAID6 into my head as the next best thing for SSD array, if it wasn't for the "distributed" part of it I wouldn't even be posting here and would go with RAID10 but the benefits of the distributed RAID got me thinking.
