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 pre-package a number of the specified options; however, Cisco Unified ICM and
Unified CC applications require special consideration to meet the high performance demands of the system. Whether
acquiring Cisco MCS servers or third-party hardware, special care should be given 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.
Furthermore, for customers with large configurations and/or long historical data retention period requirements, additional
guidelines are provided.

Note that Cisco does not currently fully support deployment of the Unified ICM/Contact Center solution on a server “blade”
chassis form factor. Evaluation of blade deployment is under consideration; in the interim, customers interested in pursuing
blade deployments have an option available to them that provides flexibility but limits Cisco support liability should
hardware or chassis control software negatively affect Unified ICM/Contact Center operation (including fault tolerant
recovery). Refer to Cisco’s policy paper on the topic for more information:

Note: Any tech-refresh planned for the PG machine, should ensure at least 40 GB of Hard Disk space mandatorily free, to
ensure that the OPC capture serviceability feature is properly turned ON. This would be very vital for troubleshooting any
PG related issues.

Recommended Redundant Hardware
Supported components:
Power supplies
Fans
Memory
Storage controllers
Disks (RAID)
Fans
Memory
Storage controllers
Disks (RAID)
Unsupported components:
Redundant network interface cards
Caution
Using network interface card teaming or other forms of redundant Ethernet
adapters has been proven to introduce packet delivery/reception problems
capable of generating latency sufficient to cause application problems.

Central Processing Unit (CPU)
Each individual core in a multi-core processor does not count as a processor towards server requirements given in
Appendix
A – Server Classes
. A processor is considered a single physical CPU, regardless of the number of cores.
