Chapter 3 Cisco CallManager Clusters
Campus Clustering Guidelines
Figure 3-6 Campus or MAN Cluster
In Figure 3-6 a Cisco CallManager is placed at each of the five buildings or sites.
This configuration ensures that, in the event of a failure, local call processing is
possible at each site. In cases where diverse routing of fiber cable negates the
requirement for a local Cisco CallManager, all call processing could be located in
one or more data centers.
Resources such as transcoding and the conferencing DSP are not shared resources
and must be provisioned per Cisco CallManager. Once again, where fault
tolerance is required, these resources require duplication, and spatial redundancy
is recommended. This can be achieved by positioning these resources in
strategically placed multi-layer switches.
