Parity group configuration
One parity group consists of a maximum of 16 VDEVs. For RAID-5 (7D + 1P) or RAID-6 (6D + 2P) levels,
amaximumof512fixed-size volumes (FVs) and a certain amount of free space are available in one
VDEV. Fo
r other RAID levels, a maximum of 256 FVs and a certain amount of space are available in
one VDEV. Each VDEV in a parity group has the same configuration, and is assigned the same FVs of
thesamesizeandRAIDlevel.
CVS fun
ctions (Volume to Space, Install CV, Volume Initialize, and Make Volume) are performed on each
VDEV. VDEVs are also separated from each other by the boundary limitation. Therefore, you cannot
define a volume across two or more VDEVs beyond the boundaries.
