Volumes

A Storage Center volume is a logical unit of storage that can represent more logical space than is physically available on the Storage Center. Before data can be written to a volume, it must be mapped to a server, then formatted as a drive. Depending on the configuration of the server, data can be written to the volume over iSCSI, Fibre Channel, or SAS.

The storage type and storage profile selected when the volume is created determines how a volume behaves. The storage type sets the datapage size and redundancy levels. The storage profile determines how data progression moves pages on the volume between tiers and RAID levels.
