Virtualization in Cisco Unity Connection 10.x


You can install 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.

Virtualization Requirements for Cisco Unity Connection 10.x

Detailed requirements for installing Cisco Unity Connection on a virtual machine are listed in the "Requirements for Installing Cisco Unity Connection on a Virtual Machine" section of System Requirements for Cisco Unity Connection Release 10.x at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/10x/requirements/10xcucsysreqs.html.

Scalability Differences Between Physical and Virtual Configurations

The maximum number of ports, the maximum number of users with mailboxes, and other scalability specifications differ between comparable physical and virtual configurations. For detailed information, see the Cisco Unity Connection 10.x Supported Platforms List at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/10x/supported_platforms/10xcucspl.html.

Installing Cisco Unity Connection 10.x Cluster Servers on Virtual Machines

Note the following about Cisco 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, 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, 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 Installation Guide for Cisco Unity Connection Release 10.x, at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/10x/installation/guide/10xcucigx.html.

Migrating Cisco Unity Connection 10.x from Physical Servers to Virtual Machines

Note the following about migrating from a Cisco Unity Connection physical server to a Unity Connection 10.x virtual machine:

The physical hosts that are supported for use in a physical environment and those that are supported in a virtual environment are mutually exclusive. If you are currently running Unity Connection in a physical environment, you must replace the server. For information on physical hosts that are supported in a virtual environment, see the Cisco Unity Connection 10.x Supported Platforms List at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/10x/supported_platforms/10xcucspl.html.

For information on migrating from physical servers to virtual machines, see the "Migrating from a Cisco Unity Connection Physical Server to a Connection 10.x Virtual Machine" chapter in the Upgrade Guide for Cisco Unity Connection Release 10.x, at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/10x/upgrade/guide/10xcucrugx.html.
