Measures reported by EqlDiskSpaceTest
Adequate space should be available in the storage device to ensure the uninterrupted functioning of the mission-critical applications that are using the storage services provided by the device. If the device runs out of space, then administrators should be intimated of the space crunch promptly so that, disk space in the device can be enhanced before service levels start taking a turn for the worse!
This test periodically checks the space usage in the device and proactively alerts administrators to potential disk space contentions so that, amends are made before application performance deteriorates.
The measures
made by this test are as
follows:
| Measurement |
Description |
Measurement
Unit |
Interpretation |
| Total_storage |
Indicates the total disk space currently available in this device.
|
GB |
|
| Used_storage |
Indicates the total disk space currently in use. |
GB |
Ideally, the value of this measure should be low. If this value grows close to that of the Total_storage measure, then you may want to consider to add more storage to the storage device, or free space in the storage device by deleting unnecessary data. |
| Snap_storage |
Indicates the total disk space currently allocated for volume snapshots.
|
GB |
Snapshots are typically used for quick recovery and offloading backup operations. If the storage device appears to be running out of space, then, the value of this measure will indicate if the volume snapshots have in any way contributed to the space crunch. |
| Replication_storage |
Indicates the total disk space currently allocated for volume replication.
|
GB |
EqualLogic's Auto-Replication remotely replicates data from one PS Group to another over a standard IP network over long distances, helping provide high levels of data protection and disaster tolerance.
In the event of a space contention on the storage device, the value of this measure will enable you to ascertain whether volume replicas are occupying too much space in the storage device.
