Table: HP 3PAR Common Provisioning Group (CPG) Summary
Column name | Description |
|---|---|
|
CPG Name |
Name assigned to the Common Provisioning Group (CPG). |
|
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). |
