Measures reported by SolFireVolTest

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.

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

The measures made by this test are as follows:

Measurement 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. Number
