8.9 Cluster Service
The cluster function, also known as cluster redundancy, is a kind of deployment method that can
improve the reliability of device. In the cluster system, there is a number of main devices and
another number of sub devices (the N+M mode), and they have a virtual IP address (the cluster IP)
for unified login and management. Under normal circumstances, the main devices are in the
working state. When the main device fails, the corresponding sub device will take over the job
automatically. When the main device recovers, the sub device will transmit the configuration data,
cluster IP address and videos recorded during the failure to the main device which then takes over
the job again.
In the N+M cluster system, there is a management server, the DCS (Dispatching Console) server,
which is responsible for timely and correct scheduling management of the main and sub devices.
When you create a cluster, the current IVSS is used as the first sub device and the DCS server by
default.
8.9.1 Configuring Cluster
Create cluster, view cluster details, recover main devices and configure the arbitration IP address.
8.9.1.1 Creating a Cluster
Creating a cluster is to add multiple devices into a cluster that requires the addition of main and sub
devices and the configuration of cluster IP.
When you create a cluster, the current Device is taken as the first sub device and the DCS server by
default, and the priority of the other sub devices is determined by the order in which they are added,
with the first sub device being the highest priority.
