Subject: Reed Solomon coding based Raid?
Date: Sat, 28 Nov 2009 16:15:28 +0100 [thread overview]
Message-ID: <4B113E90.50904@xs4all.nl> (raw)
I was wondering if there is support for a raid level where one can
choose the redundancy level. Raid 5 allows for one redundant drive,
Raid 6 for two, but there's no raid level that would support arbitrary
redundancy (even to the point of allowing one to add extra redundancy
later on, by simply putting spare drives to immediate use).
I'm just a casual Software Raid user, and have been using Raid 6 for a
small 8 TB array for a few years now and I realize that there's quite
some CPU overhead involved for such redundancy, but for my purposes
speed is not a relevant concern (10 MB/sec is enough).
