2.2 Partition RAID groups
A RAID group may have several Terabytes of total data capacity because of the size of the included
drives. Partitions allow you to break up large RAID groups into smaller, more manageable groups
without using individual lower capacity RAID groups.
Most host systems can only address 2 TB per
LUN. Partitioning increases storage efficiency by
providing more LUNs without using lower
capacity RAID groups. Partitioning allows the
creation of multiple logical volumes. Use the
FastStream SC 5300 ExpressNAV interface and
follow its directions to divide the default one
partition into subpartitions.
Setting up partitions
When you initially create RAID groups or add
RAID groups, you may partition large RAID
volumes into smaller, more manageable sizes.
