Release Note
Cisco Unified ICM/Contact Center Enterprise & Hosted Editions, Release 7.5,
Hardware and System Software Specification
©2008-2011 Cisco Systems, Inc. 6
Note: Severe network communication problems are likely when 10/100 Mbps NICs and switch ports are not BOTH
explicitly set to the capable speed in Full Duplex
operation.
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
unless otherwise specified. Components where Serial or Parallel ATA (Advanced Technology Attachment) drive use is
acceptable are explicitly identified in the applicable node’s hardware specifications.
Required controllers:
• SCSI/SAS
o Ultra160/3 (minimum)
o Ultra320 (recommended)
o
SAS 3.0Gb/s (highly recommended)
3
• ATA
o Serial (recommended)
o Parallel
Disk Drives:
• SCSI/SAS
o 3.5” Form Factor
15,000 RPM for Cisco Unified ICM and Unified CC Loggers, Historical Data Servers and other database
servers
10,000 RPM (minimum) for all other nodes
o 2.5” Form Factor
15,000 RPM preferred for database servers (if available)
10,000 RPM (standard) for all other nodes
• ATA
o
7,200 RPM
Additional Media:
• DVD drive (software installation)
Configuration guidelines:
• A dedicated on-board or add-in RAID controller must be used with a minimum of 128 MB of battery backed cache.
• Increasing the number of physical drives increases 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 of significant advantage 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.
• Two channels per external storage enclosure.
