Table: HP 3PAR Common Provisioning Group (CPG) Summary

Column name

Description

CPG Name

Name assigned to the Common Provisioning Group (CPG).

See HP 3PAR Common Provisioning Group (CPG) Detail.

Storage Array

The name of the storage array.

Allocated

Sum of the allocated size for all associated logical drives.

User

Sum of the space allocated for users on all associated logical drives.

Snap

Sum of the snap size for all associated logical drives.

Admin

Sum of the admin size for all associated logical drives.

Logical Drives

Number of allocated logical drives.

Allocation Warning

User-defined threshold that can be set for Thinly Provisioned Virtual Volumes (TPVVs) and Commonly Provisioned Virtual Volumes (CPVVs) to alert users when they reach a certain size.

Growth Incr

Unit of storage by which additional logical disks are created and allocated to a Common Provisioning Group (CPG).

Growth Warning

User-defined threshold that can be set for Common Provisioning Groups (CPGs) to alert users when they reach a certain size. Growth warning is defined as: Growth Limit - (Allocation Warning * TotalManagedSpace)/100.

Growth Limit

User-defined threshold that can be set for Common Provisioning Groups (CPGs) to cap their potential size.

% Allocated

Calculated as Allocated/Growth Limit.

Device Type (Speed)

Indicates the specified device type for physical disks: FC for Fibre Channel, NL for Nearline, and SSD for Solid State Drive. Indicates a rough performance estimation between the drive and the other drives in the system. This does not represent a rotational speed for the drives without spinning media (SSD). For FC and NL drives, the number corresponds to both a performance measurement and an actual rotational speed. For SSD drives, the number is a relative performance benchmark that takes into account in I/O per second, bandwidth and the access time.

RAID Type

Indicates the RAID type for the logical disk: r0 = RAID-0, r1 = RAID-1, r5 = RAID-5 and r6 = RAID-6. RAID10 is displayed as RAID1+0.

Set Size

Displays the set size in the number of chunklets. The default relies on the RAID type specified: 2 for RAID-1, 4 for RAID-5, and 8 for RAID-6.

Availability

Normal or degraded

Step Size

Value derived directly from the Virtual Volume (VV) or from the Common Provisioning Group (for Thinly Provisioned VVs and Commonly provisioned VVs).

Row Size

Indicates the number of sets in a row. If the field is blank, no row limit is imposed.

Disk Filter

Displays the specific logical disks for the Common Provisioning Group (CPG).
