The VMware (non HA) environment configuration supports an Active (ACT) Communication Manager virtual machine deployed on one stand alone Host with the Standby (STB) Communication Manager virtual machine deployed on a second stand alone Host with the software duplication link (NIC) directly linked together.

Communication Manager software duplication works with VMware HA as long as the Communication Manager Active and Standby virtual machines are in different data clusters.

For example, if an active Communication Manager virtual machine is deployed on a host in one data cluster (A) and standby Communication Manager virtual machine is deployed on a second host in another data cluster (B). The Communication Manager virtual machines are configured on the same sub network. The connectivity requires the software duplication link (NIC) to be tied together through a private network switch or VLAN.

For information about VMware HA in each data cluster, see Communication Manager software duplication with VMware high availability.
