The 1+1 High Availability cluster configuration ensures uninterrupted availability of media processing in cases where a media server fails. Use the High Availability configuration option when you require the capacity of only a single Avaya Aura® MS.
The High Availability configuration deploys as a Primary server and a Backup server. Only one server is active at a time. The other server is waiting in synchronized hot standby to take over instantly.
Both servers must have identical configuration so that either server can take over the full media processing load if the other server fails. Ensure that the deployed servers meet the following requirements:
Each media server in a 1+1 High Availability cluster deployed as a virtual machine must be deployed on separate but equally capable host servers with the same hardware and processor model. The VMs must be deployed using the same configuration profile so that they have the same number of vCPUs.
There is no inter-cluster communication between different 1+1 High Availability clusters. Different 1+1 High Availability clusters can use different hardware or profiles, but the specifications within a cluster must match.
