=================
* Adds support for RAIDTP (Triple Parity) and RAIDQP (Quad Parity).
For quad parity there is a limitation of using no more than 21 data
disks. This is a conseguence of the high performant parity generator
matrix used. An extension supporting up to 89 disks with Hexa (6) parity
is possible, but not yet implemented.
For Quad Parity, and only for Quad Parity, there is a limitation of
using no more than 21 data disks. This is a conseguence of the
high performant parity generator matrix used. An extension supporting
up to 89 disks with Hexa (6) parity is possible, but not yet implemented.
Note that more general approaches without these limitations are also
possible, but they would affect badly the performance.
