Measures reported by UCSCsIOModuleTest
The Cisco UCS chassis contains I/O Modules or Fabric Extenders that allow the blade servers in the chassis to communicate with Cisco UCS Fabric Interconnects. The chassis supports up to two I/O Modules, each with four I/O ports.
The Cisco UCS Fabric Extenders bring the unified fabric into the blade server enclosure, providing 10 Gigabit Ethernet connections between blade servers and the fabric interconnect, simplifying diagnostics, cabling, and management.
The Cisco UCS Fabric Extenders extend the I/O fabric between the Cisco UCS Fabric Interconnects and the Cisco Blade Server Chassis, enabling a lossless and deterministic Fibre Channel over Ethernet (FCoE) fabric to connect all blades and chassis together. Since the fabric extender is similar to a distributed line card, it does not do any switching and is managed as an extension of the fabric interconnects. This approach removes switching from the chassis, reducing overall infrastructure complexity and enabling the Cisco Unified Computing System to scale to many chassis without multiplying the number of switches needed, reducing TCO and allowing all chassis to be managed as a single, highly available management domain.
The Cisco UCS Fabric Extenders also manages the chassis environment (the power supply and fans as well as the blades) in conjunction with the Fabric Interconnects. Therefore, separate chassis management modules are not required.
Cisco UCS Fabric Extenders fit into the back of the Cisco UCS Chassis. Each Cisco UCS Chassis can support up to two Fabric Extenders, enabling increased capacity as well as redundancy.
This test monitors the overall health of each of the I/O Modules present in every chassis of the Cisco UCS Manager, and in the process, promptly alerts you to abnormalities in the power, thermal, voltage states of the modules and sudden spikes in the ambient/ASIC temperature of the modules. This way, defective I/O modules come to light.
