3.1 Server Hardware Configuration Guidelines
This section provides system integrators and customers with guidelines, supported and unsupported server
hardware, and storage configurations. Cisco MCS servers prepackage a number of the specified options; however,
Cisco Unified ICM and Unified CCE applications require special consideration to meet the high performance
demands of the system. Whether you are acquiring Cisco MCS servers or third-party hardware, take special care
to choose the appropriate level of hardware redundancy and a storage solution specific to the application nodes for
which the servers are intended. Of particular importance are the storage controller, number (and capacity) of
disks, and RAID configuration available. Additional guidelines are provided, for customers with large
configurations and those that require long historical data retention periods.

Note: When you plan a “technology refresh” upgrade for a Peripheral Gateway(PG), ensure at least 40 GB of
hard disk space free to ensure that the OPC capture serviceability feature, when enabled, will have
sufficient disk space available. This capability is vital for troubleshooting PG-related issues.
