Keywords:
A multi-server deployment requires the following IP addresses, where m is the number of physical servers, and n is the number of Presence Services instances in the cluster.
  • m VMware ESXi host IP addresses
  • n Avaya Breeze® platform Management Module IP addresses
  • n Avaya Breeze® platform Security Module IP addresses
  • One Avaya Breeze® platform Cluster IP address
For example, a cluster with five physical servers, each hosting one instance of Presence Services, requires 16 IP addresses and one Presence Services Cluster FQDN.
Note:
For scaling out to the maximum supported user capacities with multiple clusters, only fully utilized clusters are supported. For example, support of less than 84,000 users is not supported on two or three clusters of any number of nodes. 84,000 users is only supported on a single cluster of 9 nodes.
Similarly, support of less than 168,000 users is not supported on three clusters of any number of nodes. 168,000 users is only supported by two clusters of 9 nodes each.
Additionally:
  • Support of two clusters is not supported until the first cluster has reached its maximum capacity of 84,000 users on 9 nodes.
  • Support of three clusters is not supported until the first two clusters have reached their maximum capacity of 168,000 users.
