FEX /IOM in Cisco UCS

=================

IOM / FEX 知识

=================

简介

 I/O Modules (IOM) extend the fabric to the chassis, and each chassis has two

installed at the back of the chassis, next to the fans

Vblock Systems support four-port module, and eight-port modules

They attach to the fabric interconnects

UCS 2204XP

The Cisco UCS 2204XP Fabric Extender (Figure 4) has four 10 Gigabit Ethernet, FCoE-capable, SFP+ ports that connect the blade chassis to the fabric interconnect. Each Cisco UCS 2204XP has sixteen 10 Gigabit Ethernet ports connected through the midplane to each half-width slot in the chassis. Typically configured in pairs for redundancy, two fabric extenders provide up to 80 Gbps of I/O to the chassis.

 

 

UCS 2208XP

The Cisco UCS 2208XP Fabric Extender (Figure 3) has eight 10 Gigabit Ethernet, FCoE-capable, Enhanced Small Form-Factor Pluggable (SFP+) ports that connect the blade chassis to the fabric interconnect. Each Cisco UCS 2208XP has thirty-two 10 Gigabit Ethernet ports connected through the midplane to each half-width slot in the chassis. Typically configured in pairs for redundancy, two fabric extenders provide up to 160 Gbps of I/O to the chassis.
