Set Volume QoS Pattern

Overview

This function sets the QoS patterns of the volume.

The maximum bandwidth limit of the volume QoS can be changed by setting a volume QoS pattern.

Caution

  • If the Automated QoS function of ETERNUS SF Storage Cruiser is used, set the IOPS and throughput values that correspond to the bandwidth limit (No.1 to No.15) in descending order. If values are not in descending order, the Automated QoS function may not operate as expected.

Note

  • This function can be used, irrespective of whether the QoS mode has been enabled or disabled.

  • The volume QoS patterns set with this function are applied to the options of the volume QoS bandwidth limit. Refer to the [Set Volume QoS] function for details.

  • The following QoS patterns can be set.

    • Use the [Set Host QoS Pattern] function to set the host QoS patterns.

    • Use the [Set Port QoS Pattern] function to set the port QoS patterns.

    • Use the [Set LU QoS Pattern] function to set the host LUN QoS patterns.

  • The bandwidth limit can also be changed with the "set qos-bandwidth-limit" CLI command. If the bandwidth limit is changed by using CLI, that value is also applied to the bandwidth limit that is specified with Web GUI.

Operating Procedures

  1. Click [Set Volume QoS Pattern] in [Action].

  2. Specify parameters, and click the [Set] button.

    → A confirmation screen appears.

    Note

    • The volume QoS patterns (No.1 to No.15) can be reset to the default value. Click the [Default] button to display the default value and click the [Set] button. Refer to the "Volume QoS" column in "Bandwidth Limit" for the settings content.

    • Note that initializing a specific volume QoS No. is not available.
