Standard RAID levels. In computer storage, the standard RAID levels comprise a basic set of RAID (redundant array of independent disks) configurations that employ the techniques of striping, mirroring, or parity to create large reliable data stores from multiple general-purpose computer hard disk drives (HDDs).
RAID groups can contain single or multiple parity groups. You can think of the RAID group as the actual RAID container for data protection, and the parity group as a partition of that container. This way, multiple LUNs can be created from each RAID group, and ported out to the same or different servers. This allows granularity in LUN sizes being obtained from the RAID group. If each partition (parity group) is assigned to the same server, there should be no contention for the RAID group's disk resources.
