• 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.
• Most host systems can address only 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.
