Table 1‑31. Data Counters
Chart Label Description
Storage I/O Control Aggregate
IOPs
Number of I/O operations per second on the datastore, aggregated across all hosts,
and virtual machines accessing the datastore.

Storage I/O Control Activity
This chart displays the percentage of time during which Storage I/O Control actively controlled latency of
the datastore.
This chart is located in the Performance views of the datastore Performance tabs. The counter can also be
displayed for datastore cluster charts.
Table 1‑32. Data Counters

This is the percentage of time during which the Storage I/O Control actively controlled the I/O
latency for the datastore.

Average Device Latency per Host
This chart displays the average amount of latency on a host device. The chart displays the 10 hosts with the
highest device latency.
This chart is located in the Performance view of the datastore Performance tab.
Table 1‑33. Data Counters
Chart Label Description
Average Device

Measures the amount of time, in milliseconds, to complete a SCSI command issued from the
physical device.

Maximum Queue Depth per Host
This chart displays maximum queue depth that hosts are currently maintaining for the datastore. When
Storage I/O is enabled, queue depth can change over time when congestion is detected at the array.
This chart is located in the Performance view of the datastore Performance tab. The chart displays
information about the ten hosts with the highest values.
