Performance (QoS)

Overview

This function displays the performance information of the volume QoS for Host I/O.

IOPS, throughput, and the bandwidth limit for each volume can be checked.

Caution

The ETERNUS DX60 S5 does not support this function.

Note

The target volume types for this function are Standard, SDV, WSV, TPV (including NAS user volumes and Deduplication/Compression Volumes), and FTV. Note that the performance information is not displayed for ODX Buffer volumes, NAS backup volumes, NAS system volumes, and Data Container Volumes.
This function displays the performance information of volume QoS regardless of whether the QoS mode is enabled or disabled. If the QoS mode is disabled, the default bandwidth limit ("Unlimited") is displayed for all items.
Performance information is obtained when performance monitoring is operated from Web GUI, CLI, or any other monitoring software. Refer to the [Start/Stop Performance Monitoring] function for details on how to start performance monitoring with Web GUI.
The interval for acquiring performance information can be specified when starting the monitoring. When using Web GUI, the default interval is 30 seconds.
The average performance values during the specified interval are displayed.
In this manual, "volumes" include "External Volumes" if differentiation is not specifically required.
