Modifying a HyperMetro Pair

Modifying a HyperMetro Pair

Scenarios

This operation is used to modify the synchronization speed and restoration policy of a HyperMetro pair.

Prerequisites

  • You have logged in to FusionStorage Block Self-Maintenance Platform.
  • The system contains configured HyperMetro pairs.

Procedure

    1. On FusionStorage Block Self-Maintenance Platform, choose DR Service > dr > DR Cluster, click Manage HyperMetro in the row where the cluster resides.
    2. Locate the row that contains the target HyperMetro pair and click to modify parameters.

      Table 3-3 shows the parameters.

      Description

      Example Value

      Restoration Policy

      A restoration policy determines whether the system automatically synchronizes data after the fault is rectified.
      • Automatic: The system automatically synchronizes data.
      • Manual: Data synchronization must be performed manually.

      Automatic

      Synchronization Speed

      Data replication speed of the HyperMetro service
      • Low: When the synchronization speed is set to Low, data synchronization takes a relative long period of time. This speed applies to scenarios where the service load is heavy. The speed is 1 MB/s.
      • Medium: When the synchronization speed is set to Medium, data synchronization takes a relative short period of time. This speed applies to scenarios where the service load is relatively heavy. The speed is 32 MB/s.
      • High: When the synchronization speed is set to High, data synchronization takes a short period of time. This speed applies to scenarios where the service load is relatively light. The speed is 256 MB/s.
      • Highest: When the synchronization speed is set to Highest, data synchronization takes the shortest period of time. This speed applies to scenarios where the service load is light. The speed is 1024 MB/s.
