Cisco TelePresence Video Communication Servers can be clustered to provide resiliency in the enterprise. What is the maximum number of cluster members?

A 2-node cluster would provide only minimal redundancy and does not represent the maximum supported cluster size for Cisco VCS.

3 nodes is below the maximum supported cluster size and would not represent the architectural limit for VCS clustering.

Cisco TelePresence VCS supports a maximum of 6 cluster peers (nodes) in a single cluster. This limit applies to both VCS Control and VCS Expressway clusters and is a hard architectural constraint documented by Cisco to ensure synchronization and database consistency across all nodes.

7 exceeds the supported maximum of 6 cluster peers, and configuring more than 6 nodes is not supported by Cisco VCS.

15 cluster members far exceeds the supported maximum and is not a valid configuration for any Cisco VCS cluster deployment.
