Table 13 Supported Combinations of RAID Levels
S-VOL P-VOL
RAID6 RAID5 RAID1
Yes Yes Yes RAID1
Yes Yes Yes RAID5
Yes Yes Yes RAID6
•
Types of volumes
Besides normal volumes, you can use external volumes, custom-sized volumes, and LUSE
volumes. When using external volumes, custom-sized volumes, or LUSE volumes, note the
following points:
◦ External volumes
The license of XP External Storage is required.
◦ Custom-sized volumes
The license for VLL is required. To create an XP Business Copy pair with custom-sized
volumes, ensure that P-VOL is paired with S-VOLs of the same capacity and the same
emulation type.
◦ LUSE volumes
The license for LUSE is required. To create an XP Business Copy pair with LUSE volumes,
ensure that P-VOL is paired with S-VOL of the same size and the same structure. For
example, if the P-VOL is a LUSE volume where volumes of 1 GB, 2 GB and 3 GB are
combined in this order, you must ensure that the S-VOL is a LUSE volume where volumes
of 1 GB, 2 GB and 3 GB are combined in the same order.
