1.4 Volume Relationship Diagram

This is the design of volume structure of the iSCSI RAID subsystem. It describes the
relationship of RAID components. One RG (RAID group) consists of a set of VDs (Virtual
Disk) and owns one RAID level attribute. Each RG can be divided into several VDs. The
VDs in one RG share the same RAID level, but may have different volume capacity. All
VDs share the CV (Cache Volume) to execute the data transaction. LUN (Logical Unit
Number) is a unique identifier, in which users can access through SCSI commands.
