Measures reported by PureHGrpCapTest
Using this test, administrators can monitor each host group connected to the FlashArray and can pin point the host group that is utilizing the maximum space than the rest. This way, irregularities in the space utilization across the host groups can be detected at ease!. In addition, the test also proactively alerts administrators to probable slowdowns in I/O processing by specific host group, thereby enabling administrators to initiate pre-emptive actions.
Outputs of the test : One set of results for each host group connected to the target FlashArray being moniored.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| totalCapacity |
Indicates the total capacity allocated to this host group. |
TB |
The detailed diagnosis of this measure reveals the details on data reductions. |
| allUsedCapacity |
Indicates the amount of space utilized by this host group. |
TB |
Ideally, the value of this measure should be low. If this value grows closer to that of the totalCapacity measure, then administrators may want to consider adding more storage to the host group, or freeing space in the host group by deleting unnecessary data. |
| freeCapacity |
Indicates amount of space that is available for use by this host group. |
TB |
A high value is typically desired for this measure. A very low value for this measure indicates a shortage of storage space on the host group. |
| usedCapacityPCT |
Indicates the percentage of space utilized by this host group. |
Percent |
|
| freeCapacityPCT |
Indicates the percentage of space that is available for use by this host group. |
Percent |
Ideally, the value of this measure is desired to be high. |
| volumeCapacity |
Indicates the amount of space allocated to the volumes of this host group. |
TB |
The FlashArray presents disk-like volumes to connected hosts in the host group and maintains immutable snapshots of volume contents. Ideally, a low value is desired for these measures. |
| snapShotCapacity |
Indicates the amount of space allocated for storing the volume snapshots on this host group. |
