Set N+1 Hot Spare for Hybrid SAN

You can form an N+1 hot spare system with several Recording Servers. The system consists of several host servers and a spare server. When the host server fails, the spare server switches into operation, and thus increasing the video storage reliability of HikCentral Professional.

  • Make sure the Hybrid Storage Area Networks you are going to use are correctly installed and connected to the network as specified by the manufacturers. Such initial configuration is required in order to be able to connect the devices to the HikCentral Professional via network.

  • At least two online Hybrid Storage Area Networks should be added to form an N+1 hot spare system.

Note:

  • The N+1 hot spare function is only supported by Hybrid Storage Area Networks and NVRs. For details about configuring N+1 hot spare system with NVRs, see Set N+1 Hot Spare for NVR.

  • The spare server cannot be selected for storing videos until it switches to host server.

  • The host server cannot be set as a spare server and the spare server cannot be set as a host server.
