Description |
Measurement Unit |
Interpretation |
| access |
Indicates the current accessibility state of this volume. |
|
|
| volumePaired |
Indicates whether/not this volume is paired. |
|
|
| totalSize |
Indicates the total size of this volume. |
GB |
|
| clientQueueDepth |
Indicates the number of read and write requests that were in queue for this volume from the clients. |
Number |
A low value is desired for this measure.
A consistent increase in this value indicates a potential processing bottleneck with the volume.
|
| volumeSize |
Indicates the current provisioned size of this volume. |
GB |
|
| latencyUSec |
Indicates the average time taken to complete the read and write operations on this volume. |
Microsec |
|
| readLatencyUSec |
Indicates the average time taken to complete the read operations on this volume. |
Microsec |
|
| writeLatencyUSec |
Indicates the average time taken to complete write operations on this volume. |
Microsec |
|
| avgReadData |
Indicates the rate at which data was read from this volume by the clients during the last measurement period. |
MB/Sec |
|
| avgWriteData |
Indicates the rate at which data was written to this volume by the clients during the last measurement period. |
MB/Sec |
|
| totalBandwidth |
Indicates the rate at which data was read from and written to this volume during the last measurement period. |
MB/Sec |
|
| avgReadIOPS |
Indicates the average number of read operations performed on this volume per second during the last measurement period. |
IOPS |
|
| avgWriteIOPS |
Indicates the average number of write operations performed on this volume per second during the last measurement period. |
IOPS |
|
| totalIOPS |
Indicates the total number of read and write operations performed on this volume per second during the last measurement period. |
IOPS |
|
| compression |
Indicates the amount of space being saved by compressing data on this volume. |
Number |
This measure is calculated using the following formulae:
(uniqueblocks*4096) / uniqueBlocksUsed Space
where,
uniqueblocks is the number of unique blocks in the volume and
uniqueBlocksUsedSpace is the amount of space used by the unique blocks in the volume.
|
| deduplication |
Indicates the de-duplication factor of this volume. |
Number |
This measure is the ratio of the number of nonZeroBlocks to the number of uniqueBlocks. |
| thinProvisioning |
Indicates the thin provisioning factor of this volume. |
Number |
|
| efficiencyFactor |
Indicates the overall efficiency of this volume. |
