Virtualization in Cisco Unity Connection 9.x
You can install Connection on a virtual machine. In most ways, Connection running on a virtual machine works the same way as Connection running on a physical server. This chapter discusses the differences.
Installing Cisco Unity Connection 9.x Cluster Servers on Virtual Machines
Note the following about Cisco Unity Connection clusters and virtualization:
- You can install a Connection cluster on two virtual machines, or you can install a cluster on one virtual machine and one physical machine.
- If you install a 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 Connection cluster on one virtual machine and one physical machine, we recommend that you 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, Connection uses the smaller disk size to determine when the disk on which messages are stored has reached maximum capacity.
- For information on installing Connection on physical hosts and on virtual machines, see the Installation Guide for Cisco Unity Connection Release 9.x, at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/installation/guide/9xcucigx.html.
