SolidFire Volumes Test

This test auto discovers the volumes of the target storage system and helps administrators to figure out the volume that is busy processing I/O requests, detect irregularities in the distribution of I/O load across the volumes, analyze the space utilization of each volume and thus enables administrators to initiate pre-emptive measures when I/O processing capability decreases gradually.

Target of the test : A SolidFire Storage System

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the target SolidFire storage system.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Access

Indicates the current accessibility state of this volume.

 

 

Is volume paired ?

Indicates whether/not this volume is paired.

 

 

Total size

Indicates the total size of this volume.

GB

 

Client queue depth

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.

Volume size

Indicates the current provisioned size of this volume.

GB

 

Latency

Indicates the average time taken to complete the read and write operations on this volume.

Microseconds

 

Read latency

Indicates the average time taken to complete the read operations on this volume.

Microseconds

 

Write latency

Indicates the average time taken to complete write operations on this volume.

Microseconds

 

Average read bandwidth

Indicates the rate at which data was read from this volume by the clients during the last measurement period.

MB/Sec

 

Average write bandwidth

Indicates the rate at which data was written to this volume by the clients during the last measurement period.

MB/Sec

 

Bandwidth

Indicates the rate at which data was read from and written to this volume during the last measurement period.

MB/Sec

 

Average read IOPS

Indicates the average number of read operations performed on this volume per second during the last measurement period.

Reads/Sec

 

Average write IOPS

Indicates the average number of write operations performed on this volume per second during the last measurement period.

Writes/Sec

 

Total IOPS

Indicates the total number of read and write operations performed on this volume per second during the last measurement period.

IOPS

 

Compression

Indicates the compression factor of 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

De-Duplication

Indicates the de-duplication factor of this volume.

Number

This measure is the ratio of the number of nonZeroBlocks to the number of uniqueBlocks.

Thin provisioning

Indicates the thin provisioning factor of this volume.

Number

 

Overall efficiency

Indicates the overall efficiency of this volume.
