Note: Severe network communication problems are likely when 10/100 MB/s NICs and switch ports are not
both explicitly set to the capable speed in Full Duplex operation. Cisco supports the use of gigabit
(1000 MB/s) server network interface cards and gigabit network switches.

4.1.3 Storage Hardware
Cisco Unified ICM and Unified CCE are I/O intensive applications that handle call routing, process logging,
and historical archiving. I/O write operation capacity is especially critical. The use of SAS hard disk drives is
required unless otherwise specified. Components where Serial or Parallel ATA (Advanced Technology
Attachment) drive use is acceptable are explicitly identified in the hardware specifications of the applicable
node.

4.1.4 Configuration Guidelines
See the following list for guidelines on storage configuration:
A dedicated on-board or add-in RAID controller must be used with a minimum of 128 MB of battery
backed cache.
backed cache.
Increasing the number of physical drives may increase the overall fault tolerance of the disk array.
Use controllers with multiple channels connected to discrete drive bays or backplanes.
Note:
Multiple controller channels can be significantly advantageous when there are multiple drive bays
and backplane connections. Each channel of the controller can connect to a separate backplane
connection, and arrays split between the channels and backplanes can take advantage of the
increased throughput as well as increased resiliency.

increased throughput as well as increased resiliency.
Each external storage enclosure has two channels.
Multiple external storage enclosures are desirable (when needed) for increased performance and fault
tolerance.

External storage enclosures with dedicated RAID controllers are supported with MCS server systems.
