Modifying the Properties of a HyperMetro

Modifying the Properties of a HyperMetro

Through this operation, you can modify the speed and recovery policy of a HyperMetro pair.


A HyperMetro pair has been successfully configured for the storage system.


  1. Log in to DeviceManager.
  2. Choose Data Protection > HyperMetro > HyperMetro Pair.
  3. Click the HyperMetro Pair tab.

    The HyperMetro Pair management page is displayed.

  4. Select a HyperMetro pair whose properties you want to modify and click Properties.

    The Properties of HyperMetro Pair dialog box is displayed.

  5. On the General tab page, you can view the link information about the HyperMetro pair. Click the Synchronize Information tab to modify related parameters. Table 3-3 explains the related parameters.

    Table 3-3 Parameters of HyperMetro properties



    Example Value


    Data replication speed of a HyperMetro pair.

    • Low: Data replication takes a relatively long time. This value is applicable to scenarios where the service load is heavy. The speed ranges from 0 MB/s to 5 MB/s.
    • Medium: Data replication takes a relatively short time. This value is applicable to scenarios where the service load is relatively heavy. The speed ranges from 10 MB/s to 20 MB/s.
    • High: Data replication takes a short time. This value is applicable to scenarios where the service load is relatively light. The speed ranges from 50 MB/s to 70 MB/s.
    • Highest: Data replication takes the shortest time. This value is applicable to scenarios where the service load is light. The speed is greater than 100 MB/s.

    [Value range]

    Possible values are Low, Medium, High, and Highest.

    Recovery Policy

    A recovery policy determines whether the system automatically synchronizes data after a HyperMetro fault is rectified.

    • Automatic: The system automatically synchronizes data.
    • Manual: The synchronization operation must be performed manually.

    [Value range]

    Possible values are Automatic and Manual.

    Isolation Switch

    After the Isolation Switch is turned on, the system will suspend the HyperMetro pair when the difference between the write I/O latency of the two storage arrays is greater than the isolation switch. The storage array with the longer write I/O latency will stop providing services.



    Isolation Threshold (ms)

    Write I/O latency difference between the host and HyperMetro storage arrays.
