3. Volume Set Function
A volume set is seen by the host system as a single logical device, and is organized in a RAID level with one or more physical disks. RAID level refers to the level of data performance and protection of a Volume Set. The RAIDBank4 supports up to 4 simultaneous volume sets in varying RAID level configurations. Creating volume sets require that a RAIDset is already defined- to create a RAIDset please see section 2.1 “Create RAIDset” of this chapter. A Volume Set capacity can consume all or a portion of the disk capacity available in a RAID Set, and multiple Volume Sets can exist on a group of disks in a RAID Set. All Volume Sets created in a specified RAID Set will reside on all the physical disks in the RAID Set, and the data spread evenly across all the disks in the RAID Set. To enter a Volume Set Function, press ENT to enter the main menu. Scroll to select the Volume Set Functions option and then press ENT to enter further submenus.
