Set N+1 Hot Spare for NVR

Set N+1 Hot Spare for NVR

You can form an N+1 hot spare system with several NVRs (Network Video Recorder). The system consists of several host servers and a spare server. When the host server fails, the spare server switches into operation (such as video recording, searching video for playback, etc.), thus increasing the video storage reliability of HikCentral Professional.

  • At least two online NVRs should be added to form an N+1 hot spare system. For details about adding NVR, see Manage Encoding Device.

  • Make sure the NVRs 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.

If the N+1 hot spare settings have already been configured on the NVR, click Physical View > Encoding Device > N+1 Hot Spare > Get Hot Spare Settings from Device to upload the hot spare settings from the device to HikCentral Professional. If the N+1 hot spare settings haven't been configured on the device, perform the following task to set N+1 hot spare for the NVR.

Note:

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

  • 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.
