CiscoUCS 2200 Series FEXes bring the unified fabric into the blade server enclosure, providing 10 Gigabit
Ethernetconnections between blade servers and the fabric interconnect, simplifying diagnostics, cabling, and
management.
TheCisco UCS 2200 Series extends the I/O fabric between the fabric interconnects and the Cisco UCS 5100
SeriesBlade Server Chassis, enabling a lossless and deterministic Fibre Channel over Ethernet (FCoE) fabric
toconnect all blades and chassis together. Because the FEX is similar to a distributed line card, it does not
doany switching and is managed as an extension of the fabric interconnects. This approach removes switching
fromthe chassis, reducing overall infrastructure complexity and enabling the Cisco Unified Computing System
toscale to many chassis without multiplying the number of switches needed, reducing TCO and allowing all
chassisto bemanaged as asingle, highlyavailable management domain.
TheCisco 2200 Series also manages the chassis environment (the power supply and fans as well as the blades)
inconjunction with the fabric interconnect. Therefore, separate chassis management modules are not required.
CiscoUCS 2200 Series FEXes fit into the back of the Cisco UCS 5100 Series chassis. Each Cisco UCS 5100
Serieschassis can support up to two FEXes, enabling increased capacity as well as redundancy.
