ServerView Resource Orchestrator Cloud Edition V3.2.0 NS Option Instruction

1.5.2 When Using Internal Disks of a Server

This section explains high availability when using the internal disk of the server used in the environment on which the NS appliance is deployed.

• High Availability as a Resource

  • Redundancy Function of NS Appliance

    This function is to take over operations without continuing L-Platform communications, by the process of a standby NS Appliance taking over from the operating NS Appliance, even if the operating NS Appliance goes down.
    For details on the redundancy function of NS Appliance, refer to "1.2.6 High-availability Function".

• Disaster Recovery

  Physical servers for NS Appliances are not the targets of Disaster Recovery.
  When taking over the settings of an NS Appliance being used by a primary site to the backup site, perform the following procedure:

  1. Regularly back up the definition of the NS Appliance of the primary site.
     For details, refer to "10.2.2 Backup of Network Devices" in the "Operation Guide CE".

  2. Restore the definition backed up in step 1 to an NS Appliance when migrating to the backup site.
     For details, refer to "10.2.3 Restoration of Network Devices" in the "Operation Guide CE".
