Nested-RAID: The Triple Lindy

“Thus far we have talked about single-level RAID configurations
and Nested RAID configurations. But we’ve artificially restricted
ourselves to only two levels in Nested RAID. Couldn’t we have three
RAID levels or more? The answer is yes, and in this article we’ll
talk about three levels (the proverbial “Triple Lindy”) and have
some fun with a couple of examples.

“RAID “Triple Lindy” Introduction

“In the previous three articles, the concept of RAID was
introduced, Nested RAID configurations starting with RAID-0 and
RAID-1 based Nested RAID configurations were explored, and RAID-5
and RAID-6 based Nested RAID configurations were discussed. Recall
that Nested RAID allow standard RAID configurations such as RAID-0,
RAID-1, RAID-5, and RAID-6, to be combined in multiple levels. For
example, RAID-0 and RAID-1 could be combined to create RAID-10. But
Nested RAID does not restrict the number of RAID levels. So what
would happen if three levels of RAID were combined for a RAID
configuration? Would it have even more performance along with great
data redundancy? Or could I let my “Data OCD” take control and
produce a RAID configuration that can withstand the loss of a huge
number of drives without losing access to data?”
