The storage device panel displays server-wide storage utilization statistics.

By default, the information is grouped per storage device. You can also group the statistics per path, per world, or per partition.

Storage Device Panel Statistics

Column

Description

DEVICE

Name of the storage device.

PATH

Path name. This name is visible only if the corresponding device is expanded to paths. See the interactive command p in Storage Device Panel Interactive Commands.

WORLD

World ID. This ID is visible only if the corresponding device is expanded to worlds. See the interactive command e in Storage Device Panel Interactive Commands. The world statistics are per world per device.

PARTITION

Partition ID. This ID is visible only if the corresponding device is expanded to partitions. See interactive command t in Storage Device Panel Interactive Commands.

NPH

Number of paths.

NWD

Number of worlds.

NPN

Number of partitions.

SHARES

Number of shares. This statistic is applicable only to worlds.

BLKSZ

Block size in bytes.

NUMBLKS

Number of blocks of the device.

DQLEN

Current device queue depth of the storage device.

WQLEN

World queue depth. This is the maximum number of ESXi VMkernel active commands that the world is allowed to have. This is a per device maximum for the world. It is valid only if the corresponding device is expanded to worlds.

ACTV

Number of commands in the ESXi VMkernel that are currently active. This statistic applies to only worlds and devices.

QUED

Number of commands in the ESXi VMkernel that are currently queued. This statistic applies to only worlds and devices.

%USD

Percentage of the queue depth used by ESXi VMkernel active commands. This statistic applies to only worlds and devices.

LOAD

Ratio of ESXi VMkernel active commands plus ESXi VMkernel queued commands to queue depth. This statistic applies to only worlds and devices.

CMDS/s

Number of commands issued per second.

READS/s

Number of read commands issued per second.

WRITES/s

Number of write commands issued per second.

MBREAD/s

Megabytes read per second.

MBWRTN/s

Megabytes written per second.

DAVG/cmd

Average device latency per command in milliseconds.

KAVG/cmd

Average ESXi VMkernel latency per command in milliseconds.

GAVG/cmd

Average guest operating system latency per command in milliseconds.

QAVG/cmd

Average queue latency per command in milliseconds.

DAVG/rd

Average device read latency per read operation in milliseconds.

KAVG/rd

Average ESXi VMkernel read latency per read operation in milliseconds.

GAVG/rd

Average guest operating system read latency per read operation in milliseconds.

QAVG/rd

Average queue read latency per read operation in milliseconds.

DAVG/wr

Average device write latency per write operation in milliseconds.

KAVG/wr

Average ESXi VMkernel write latency per write operation in milliseconds.

GAVG/wr

Average guest operating system write latency per write operation in milliseconds.

QAVG/wr

Average queue write latency per write operation in milliseconds.

ABRTS/s

Number of commands aborted per second.

RESETS/s

Number of commands reset per second.

PAECMD/s

Number of PAE commands per second. This statistic applies to only paths.

PAECP/s

Number of PAE copies per second. This statistic applies to only paths.

SPLTCMD/s

Number of split commands per second. This statistic applies to only paths.

SPLTCP/s

Number of split copies per second. This statistic applies to only paths.

The following table displays the interactive commands you can use with the storage device panel.

Storage Device Panel Interactive Commands

Command

Description

e

Expand or roll up storage world statistics. This command allows you to view storage resource utilization statistics separated by individual worlds belonging to an expanded storage device. You are prompted for the device name. The statistics are per world per device.

P

Expand or roll up storage path statistics. This command allows you to view storage resource utilization statistics separated by individual paths belonging to an expanded storage device. You are prompted for the device name.

t

Expand or roll up storage partition statistics. This command allows you to view storage resource utilization statistics separated by individual partitions belonging to an expanded storage device. You are prompted for the device name.

r

Sort by READS/s column.

w

Sort by WRITES/s column.

R

Sort by MBREAD/s column.

T

Sort by MBWRTN column.

N

Sort first by DEVICE column, then by PATH, WORLD, and PARTITION column. This is the default sort order.

L

Changes the displayed length of the DEVICE column.
