Virtualization in Cisco Unity Connection 10.x
You can install Cisco Unity Connection on a virtual machine. In most ways, Unity Connection running on a virtual machine works the same way as Unity Connection running on a physical server. This chapter discusses the differences.
Installing Unity Connection Cluster Servers on Virtual Machines
Note the following about Unity Connection clusters and virtualization:
- You can install a Unity Connection cluster on two virtual machines, or you can install a cluster on one virtual machine and one physical machine.
- If you install a Unity Connection cluster on two virtual machines, the virtual machines must not be on the same blade. Ideally, the virtual machines will be on separate chassis.
- If you install a Unity Connection cluster on one virtual machine and one physical machine, you should configure the virtual machine to match the specifications of the physical server for CPU, memory, and disk space. If disk space on the physical server and virtual machine do not match, Unity Connection uses the smaller disk size to determine when the disk on which messages are stored has reached maximum capacity.
- For information on installing Unity Connection on physical hosts and on virtual machines, see the “Installing Cisco Unity Connection” chapter of the Install, Upgrade, and Maintenance Guide for Cisco Unity Connection, Release 10.x, available at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/10x/install_upgrade/guide/10xcuciumgx/10xcuciumg010.html.
