HP 3PAR Storage CPG Capacity Test

A common provisioning group (CPG) creates a virtual pool of logical disks that allows virtual volumes to share the CPG's resources and allocates space on demand. A CPG allows up to 65,536 virtual volumes to share a CPG’s assigned resources. The allocated capacity of CPG includes usable space, snap space and administration space. This test periodically checks the usage of those spaces on the target storage system and proactively alerts administrators to potential storage space contentions so that, amends are made before application performance deteriorates.

Target of the test : A HP 3PAR Storage system

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the storage CPG on the storage system.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the Storage system.

Port

The port number at which the Storage system listens. The default is NULL.

User and Password

Specify the credentials of a user who has the right to execute API commands on the storage device and pull out metrics. To monitor the HP 3PAR Storage system,  you will have to provide the credential of a user who has been assigned the Monitor role.

Confirm Password

Confirm the password by retyping it here.

SSH Port

The Secured Shell (SSH) port number at which the Storage system listens. The default is 22.

Jar

By default, this test uses the wbem.jar for metrics collection. This is why, the wbem option is selected by default. If you want the test to use the sblimCIMClient.jar for collecting metrics, choose the sblim option here.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

User space total

Indicates the total user storage space of logical disks.

TB

 

User space used

Indicates the used storage space of logical disks.

TB

Ideally, this value should be low.

User space free

Indicates the amount of storage space available in logical disks.

TB

A high value is desired for this measure. A very low value for this measure indicates a shortage of user storage space on associated logical disks.

User space free percentage

Indicates the percentage of storage space available in logical disks.

Percent

 

Snap space total

Indicates the total snap size of logical disks.

TB

 

Snap space used

Indicates the used snap size of logical disks.

TB

Ideally, this value should be low.

Snap space free

Indicates the amount of snap size available in logical disks.

TB

A high value is desired for this measure. A very low value for this measure indicates a shortage of snap size on associated logical disks.

Snap space free percentage

Indicates the percentage of snap size available in logical disks.

Percent

 

Administration space total

Indicates the total administration size of logical disks.

TB

 

Administration space used

Indicates the used administration size of logical disks.

TB

Ideally, this value should be low.

Administration space free

Indicates the amount of administration size available in logical disks.

TB

A high value is desired for this measure. A very low value for this measure indicates a shortage of administration size on associated logical disks.

Administration space free percentage

Indicates the percentage of administration size available in logical disks.
