and more disk drives can be included. A RAID 1E pool can be built
from three or more disk drives. Also referred to as a
striped mirror.
RAID 10 pool Built from two or more equal-sized RAID 1 pools. Data in a RAID
10 pool is both striped and mirrored.
RAID 5 pool A minimum of three disk drives, with data striping and parity data
to provide redundancy. See also parity.
RAID 50 pool Built from six to forty-eight disk drives configured as two or more
RAID 5 pools. Stripes stored data and parity data across all disk
drives in both RAID 5 pools.

data to provide redundancy. However, RAID 6 pools include
two
independent sets of parity data instead of one. Both sets of parity
data are striped separately across all disk drives in the pool. Also
referred to as
dual drive failure protection.
