Flex-RAID

Flex-RAID technology utilizes the industry-standard RAID levels 0, 1, 5, and 6. To 
reconfigure the default Flex-RAID Volume C, split it into multiple volumes, specify a different 
RAID level, or specify a larger reserved space for snapshots, and reconfigure your volume. 
See 

Flex-RAID advantages include:

The default volume can be deleted and re-created, with or without snapshot reserved 
space.

Hot spare disk is supported.

Volume expansion without data loss is supported.

Full volume management is available. You can create RAID level 0, 1, 5, or 6 

volumes, specify the volume size, delete a disk from a volume, assign a hot spare, 
and so on.

Multiple volumes are supported, each with a different RAID level, snapshot schedule, 
and disk quota definition.

Each disk can be replaced, one by one, then rebuilt; after the last disk is replaced, 

another data volume using the newly added capacity can be configured.
