RAID Implementations
The TagmaStore WMS100 subsystem supports RAID 1+0, RAID 1, RAID 5, RAID6, or an intermix.
Notes on using RAID0:
RAID1+0 groups provide data redundancy like RAID1 by copying all the contents of two
disk drives to another pair. Different from RAID1, data striping is performed for a
maximum of 16 sets of two disk drives.
RAID1 array groups consist of at least two disk drives in a mirrored configuration. Data is
mirrored across the groups of two adjacent drives. The stripe consists of two data
chunks.
RAID5 applies 2 to 15 data disks and has a parity disk which performs the data stripping.
RAID 6 applies 2 to 28 data disks, and has two parity disks performing the data stripping.
Configuration with two parity disks provides redundancy that can sustain two point
failures.
