Unified CM Servers
Unified CM clusters utilize various types of servers, depending on the scale, performance, and
redundancy required. They range from non-redundant, single-processor servers to highly redundant,
multi-processor servers.

Unified CM is supported only on specific hardware platforms. For a list of the currently supported
hardware configurations, refer to the documentation on Cisco MCS 7800 Series Unified CM appliances,

lists the types of servers you can use for Unified CM for Unified CCE deployments, the main
characteristics, and typical agent limits. These limits are not guaranteed to be possible in all deployment
scenarios, but in normal call center deployments, these limits are typically possible. However, in all
cases you must use the Cisco Unified CM Capacity Tool or the Unified Communications Sizing Tool to
verify that a specific system design will be supported.
