Measures reported by PureArrCapTest

Adequate space should be available in the FlashArray to ensure the uninterrupted functioning of the mission-critical applications that are using the storage services provided by the FlashArray. If the FlashArray runs out of space, then administrators should be intimated of the space crunch promptly so that, storage space in the FlashArray can be enhanced before service levels start taking a turn for the worse! This test periodically checks the space usage in the FlashArray and proactively alerts administrators to potential storage space contentions so that, amends are made before application performance deteriorates.

Outputs of the test : One set of results for the FlashArray being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
totalCapacity Indicates the total storage space available in the FlashArray. TB The detailed diagnosis of this measure reveals the details about data reductions on the array.
allUsedCapacity Indicates the amount of storage space that is currently in use on the FlashArray. 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 FlashArray, or freeing space in the FlashArray by deleting unnecessary data.
freeCapacity Indicates the amount of storage space that is available for use on the FlashArray. 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 FlashArray.
usedCapacityPCT Indicates the percentage of storage space utilized on the FlashArray. Percent  
freeCapacityPCT Indicates the percentage of storage space available for use on the FlashArray. Percent Ideally, the value of this measure is desired to be high.
volumeCapacity Indicates the amount of storage space allocated for volumes. TB Typically, volumes are used to store non-shared data in the FlashArray. This measure shows the size of non-shared data on the FlashArray.
snapShotCapacity Indicates the amount of storage space allocated for volume snapshots. TB Snapshots are typically used for quick recovery and offloading backup operations. If the FlashArray appears to be running out of space, then, the value of this measure will indicate if the snapshots have in any way contributed to the space crunch.
sharedCapacity Indicates the amount of storage space allocated for shared (deduplicated) data. TB  
systemCapacity Indicates the amount of storage space utilized by RAID-3D parity and other metadata TB
