Intelligent Fabric Modules
The Cisco UCS X9508 contains Intelligent Fabric Modules (IFMs) on the rear of the server chassis. IFMs
have multiple functions in the server chassis:
• Data traffic: IFMs support network-level communication for traditional LAN and SAN traffic as well as
aggregating and disaggregating traffic to and from individual compute nodes.
• Chassis health: IFMs monitor common equipment in the server chassis, such as fan units, power supplies,
environmental data, LED status panel, and so on. Management functions for the common equipment is
supported through IFMs.
• Compute Node health: IFMs monitor Keyboard-Video-Mouse (KVM) data, Serial over LAN (SoL) data,
and IPMI data for the compute nodes in the chassis, as well as provide management of these features.
IFMs must always be deployed in pairs to provide redundancy and failover to safeguard system operation.

The Cisco UCS 9108 Intelligent Fabric Module (UCSX-I-9108-25G) is an IFM that supports aggregate data
throughput of 2TB/s through two groups of four optical ports.
