Set Port QoS Pattern

Overview

This function sets the QoS patterns of the port.

The maximum bandwidth limit of the port QoS can be changed by setting a port 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 port QoS patterns set with this function are applied to the options of the port QoS bandwidth limit. Refer to the [Set FC Port QoS] function, the [Set iSCSI Port QoS] function, or the [Set SAS Port 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 LU QoS Pattern] function to set the host LUN QoS patterns.

    • Use the [Set Volume QoS Pattern] function to set the volume 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.

Item Description Setting values

No.

The pattern number (0 to 15) of the port QoS is displayed.

IOPS

Enter the maximum performance (IOPS).

Note that "No.0" (Unlimited) cannot be changed.

The current value is displayed when this function starts.

No.0

"Unlimited"

No.1 - No.15

60 - 4294967295

Refer to the "Port QoS" column in "Bandwidth Limit" for the default value.

Throughput (MB/s)

Enter the maximum performance (throughput value).

Note that "No.0" (Unlimited) cannot be changed.

The current value is displayed when this function starts.

No.0

"Unlimited"

Operating Procedures

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

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

    → A confirmation screen appears.

    Note

    • The port 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 "Port QoS" column in "Bandwidth Limit" for the settings content.

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

  3. Click the [OK] button.

    → The port QoS pattern setting starts.

  4. Click the [Done] button to return to the [Host-LU QoS] screen.
