Volume Types
Depending on the underlying RAID Group type, you may create the following types of volumes:
Volume on RAID Group for Single Volume or iSCSI LUN (Block-Level)
Allocates all storage capacity on a RAID Group to a single volume. Provides better performance but less
management flexibility.
Allows creation of multiple iSCSI LUNs (Regular File) on volumes.
Volume on RAID Group for Multiple Volumes or iSCSI LUNs (Block-Level)
Allocates a designated portion of the storage capacity on a RAID Group to create a volume. Provides better
management flexibility, allowing you to expand volume size or create additional volumes as needed.

extending the lifetime of your SSDs.
