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 GiB 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 accessible by host systems

The relationship between HP 3PAR storage system data layers is illustrated in
