Statistics in the Storage Adapter panel are aggregated per storage adapter by default. Statistics can also be viewed per storage path.

Table 1. Storage Adapter Panel Statistics
Column Description
ADAPTR Name of the storage adapter.
PATH Storage path name. This name is only visible if the corresponding adapter is expanded. See interactive command e in Storage Adapter Panel Interactive Commands.
NPTH Number of paths.
AQLEN Current queue depth of the storage adapter.
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.
RESV/s Number of SCSI reservations per second.
CONS/s Number of SCSI reservation conflicts per second.
DAVG/cmd Average device latency per command, in milliseconds.
KAVG/cmd Average ESXi VMkernel latency per command, in milliseconds.
GAVG/cmd Average virtual machine 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 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 latency per write operation, in milliseconds.
FCMDS/s Number of failed commands issued per second.
FREAD/s Number of failed read commands issued per second.
FWRITE/s Number of failed write commands issued per second.
FMBRD/s Megabytes of failed read operations per second.
FMBWR/s Megabytes of failed write operations per second.
FRESV/s Number of failed SCSI reservations per second.
ABRTS/s Number of commands cancelled per second.
RESETS/s Number of commands reset per second.
PAECMD/s The number of PAE (Physical Address Extension) commands per second.
PAECP/s The number of PAE copies per second.
SPLTCMD/s The number of split commands per second.
SPLTCP/s The number of split copies per second.

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

Table 2. Storage Adapter Panel Interactive Commands
Command Description
e Toggles whether storage adapter statistics appear expanded or unexpanded. Allows you to view storage resource utilization statistics broken down by individual paths belonging to an expanded storage adapter. You are prompted for the adapter name.
r Sorts by READS/s column.
w Sorts by WRITES/s column.
R Sorts by MBREAD/s read column.
T Sorts by MBWRTN/s written column.
N Sorts first by ADAPTR column, then by PATH column. This is the default sort order.
