HP 3PAR Storeserv Tutorial

HP 3PAR Storeserv Tutorial:

HP 3PAR storage systems include the hardware components that physically store your data and the software applications that manage your data.

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

• Physical Disks

• Chunklets

• Logical Disks

• Common Provisioning Groups

• Virtual Volumes

Chunklets are drawn from physical disks,

logical disks are created from groups of chunklets, common provisioning groups (CPGs) are groups of logical disks, and virtual volumes use storage space provided by CPGs. The virtual volumes are exported to hosts and are the only data layer visible to hosts.

Physical Disks

A physical disk is a hard drive mounted on a drive magazine located in an HP 3PAR storage system drive cage.

Chunklets

Physical disks are divided into chunklets. Each chunklet occupies contiguous space on a physical disk. On F-Class and T-Class systems all chunklets are 256 MB. On 10000 and 7000 systems all chunklets are 1 GB. Chunklets are automatically created by the HP 3PAR Operating System and they are used to create logical disks.

Logical Disks

A logical disk is a collection of physical disk chunklets arranged as rows of RAID sets. Each RAID set is made up of chunklets from different physical disks. Logical disks are pooled together in Common Provisioning Groups (CPGs) which allocate space to virtual volumes.

Common Provisioning Groups

A CPG is a virtual pool of logical disks that allocates space to virtual volumes on demand. A CPG allows virtual volumes to share the CPG resources. You can create fully provisioned virtual volumes (FPVVs) and thinly-provisioned virtual volumes (TPVVs) that draw space from a CPG logical disk pool.

Virtual Volumes

Virtual volumes draw their resources from CPGs, and volumes are exported as logical unit numbers (LUNs) to hosts. Virtual volumes are the only data layers visible to the hosts.

Fully-provisioned Virtual Volumes

An FPVV is a volume that uses logical disks that belong to a CPG. Unlike TPVVs, FPVVs have a set amount of user space that is allocated for user data.

Thinly-provisioned Virtual Volumes

A TPVV is a volume that uses logical disks that belong to a CPG. TPVVs associated with the same CPG draw space from the logical disk pool as needed, allocating space on demand in small increments for each controller node.

Physical Copies

A physical copy is a full copy of a volume. The data in a physical copy is static; it is not updated with subsequent changes to the parent volume. The parent volume is the original volume that is copied to the destination volume.

Virtual Copy Snapshots

A snapshot is a virtual copy of a base volume. The base volume is the original volume that is copied. Unlike a physical copy, which is a duplicate of an entire volume, a virtual copy only records changes to the base volume.

Exporting Virtual Volumes

For a host to see a virtual volume, the volume must be exported as a LUN. Volumes are exported by creating Virtual Volume-LUN pairings (VLUNs) on the system.
