Chassis Switching Fabric
Because each CMM module contains its own factory-installed fabric board, only one additional Chassis
Fabric Modules (CFMs) is required for switch operations. However, to provide wire rate bandwidth
performance and fabric redundancy, up to two Chassis Fabric Modules (CFMs) can be added. For more
detailed information, refer to the section below.
Fabric Boards and Chassis Bandwidth
In order to operate at full wire rate, OmniSwitch 10K switches must have a minimum of three fabric
boards operating at all times.
Each fabric board provides slightly more than 33 percent of wire rate, so three fabric boards provide a full
100 percent of wire rate bandwidth for the chassis. The addition of a fourth fabric board (by installing a
redundant CFM module) provides an extra margin of throughput and redundancy.
Each NI module consists of port groups connected by the fabric boards. The following chart outlines
performance per port group, based on the number of fabric boards installed.
