Not to quibble (much), but VSM operates a log structured filesystem. (There are indeed redundant parity tracks, which is the hallmark of RAID 6 devices, but that log structure ameliorates the well known RAID 5/6 write penalty to some extent.) I wouldn't call it strictly RAID 6. -- David Andrews A. Duda and Sons, Inc.
