4 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

rd
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/Unified CC 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/Unified CC operation (including fault tolerant
recovery). Refer to Cisco’s policy paper on the topic for more information:

Recommended Redundant Hardware
Supported components:
Power supplies
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
Cisco has qualified and now supports dual-core Intel processors on its full range of products. Each individual core in a
multi-core processor does not count as a processor towards server requirements given in

Cisco highly recommends the use of gigabit (1000 Mbps) server network interface cards and gigabit network switches.
Storage Hardware
Cisco Unified ICM and Unified CC are I/O intensive applications that handle call routing, process logging, and historical
archiving. I/O write operation capacity is of particular criticality. The use of SCSI hard disk drives is the default required
