8 Storage Software Components

HP 3PAR StoreServ Storage systems include both the hardware components that physically store

your data and the software applications that manage your data.

An HP 3PAR storage system is composed of the following logical data layers:

• Physical disks

• Chunklets—On an HP 3PAR StoreServ 7000 Storage system, chunklets are 1-GB units of disk

space

• Logical disks—Advanced storage components that add RAID stability

• CPGs (Common Provisioning Groups)—Shared pools of storage space

• Virtual Volumes—Data containers that are accessible by host systems

The relationship between HP 3PAR storage system data layers is illustrated in Figure 2 (page 41).
