Chapter 10 Sizing Unified CCE Components and Servers
Additional Sizing Factors
Many variables in the Unified CCE configuration and deployment options can affect the hardware
requirements and capacities. This section describes the major sizing variables and how they affect the
capacity of the various Unified CCE components. In addition,
requirements and capacities. This section describes the major sizing variables and how they affect the
capacity of the various Unified CCE components. In addition,
summarizes the sizing
variables and their effects.
Busy Hour Call Attempts (BHCA)
The number of calls attempted during a busy hour is an important metric. As BHCA increases, there is
an increase in the load on all Unified CCE components, most notably on Unified CM, Unified IP IVR,
and the Unified CM PG. The capacity numbers for agents assume up to 30 calls per hour per agent. If a
deployment requires more than 30 calls per hour per agent, it will decrease the maximum number of
supported agents for the agent PG. Handle such occurrences on a case-by-case basis.

Agents
The number of agents is another important metric that will impact the performance of most Unified CCE
server components, including Unified CM clusters. For the impact of agents on the performance of
Unified CM components, see

Average Skill Groups per Agent
The number of skill groups per agent (which is independent of the total number of skills per system) has
significant effects on the CTI OS Server, the Agent PG, and the Call Router and Logger. Limit the
number of skill groups per agent to 5 or fewer, when possible, and that you periodically remove unused
skill groups so that they do not affect system performance. You can also manage the effects on the CTI
OS server by increasing the value for the frequency of statistical updates.
