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
• Chassis health: IFMs monitor common equipment in the server chassis, such as fan units, power supplies,
• Compute Node health: IFMs monitor Keyboard-Video-Mouse (KVM) data, Serial over LAN (SoL) data,
IFMs must always be deployed in pairs to provide redundancy and failover to safeguard system operation.
