Fig. 2.5 Physical Locations of Drive Members
A drive can be assigned as the Local Spare Drive that serves one specific logical drive, or as a
Global Spare Drive that participates in the rebuild of any logical drive. Spares automatically
joins a logical drive in order to replace a failed member when a drive fails. Spares are not
applicable to logical drives that have no data redundancy (NRAID and RAID 0).
Fig. 2.6 Partitions in Logical Configurations
You may divide a logical drive or logical volume into partitions of desired capacity, or use the
entire capacity as a single volume.
1. It is not a requirement to partition any logical configuration. Partitioning helps to manage
a massive capacity.
2. Note that a logical drive cannot be included in a logical volume if it has already been par-
titioned.
