HP 3PAR Storage Array Capacity Test

Adequate space should be available in the storage arrays to ensure uninterrupted functioning of the mission-critical applications that are using the storage services provided by the storage arrays. If a storage array is about to run out of space, then, administrators should be intimated of the space crunch well in advance so that, storage space in the storage array can be enhanced before service levels start taking a turn for the worse! This test periodically checks the space usage in each storage array 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 array on the storage system being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.


The IP address of the Storage system.


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.


Set this flag to True, if the storage system being monitored is SSL-enabled. By default this flag is set to False.


By default, the target HP 3PAR Storage system is embedded within the storage platform. Therefore, this flag is set to True, by default.

CIM Server Port

The SMI–S provider of the HP 3PAR Storage system provides access for monitoring and management via the HTTP and HTTPS protocols for CIM API request/response semantics. To enable the eG agent to access the SMI-S Provider, invoke the CIM API commands, and collect the required metrics, you need to specify the service port on the SMI- S provider in the CIM Server Port text box that listens for HTTP/HTTPS requests for CIM API semantics. By default, this is port 5988. If the service port on the SMI-S Provider listens only to HTTPS requests, then specify the port as 5989.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total capacity

Indicates the total storage space available in the storage array.



Allocated capacity

Indicates the amount of storage space that is allocated to from the storage array.


If the value of this measure grows closer to the value of the Total capacity measure, then administrators may want to consider adding more storage to the storage array, or freeing space in the storage array by deleting unnecessary data.

Allocated capacity percentage

Indicates the percentage of storage space that is allocated to from the storage array.



Free capacity

Indicates the amount of storage space that is available for use on the storage array.


A high value is desired for this measure. A very low value for this measure indicates a shortage of storage space on the storage array.
