Cisco UCS 2200 series Fabric Extender brings the unified fabric into the blade server enclosure, providing 80 Gigabit Ethernet connections between blade servers and the fabric interconnect, simplifying diagnostics, cabling, and management.
The Cisco UCS 2200 series extends the I/O fabric, enabling a lossless and deterministic Fiber 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 perform 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 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 2200 series also manages the chassis environment (the power supply and fans as well as the blades) in conjunction with the fabric interconnect.
The Cisco UCS 2208XP Fabric Extender has eight 10 Gigabit Ethernet, FCoE-capable, and enhances Small Form-Factor Pluggable (SFP+) ports that connect the blade chassis to the fabric interconnect. 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.
Management by Cisco UCS manager
It reduces TCO by removing management modules from the chassis, making the chassis stateless. Provides a single, highly available management domain for all system chassis, reducing administrative tasks.
It simplifies operation by automatically synchronizing firmware levels between the fabric extenders and interconnects.
It decreases TCO by reducing the number of network interface cards (NICs), host bus adapters (HBAs), switches, and cables needed.
It increases availability with an active-active data plane.
It reduces TCO by optimizing overall system capacity to match actual workload demands.
It removes the need for chassis management modules.
It provides a reliable, robust foundation for unifying LAN and SAN traffic on a single transport.
Priority flow control (PFC)
It simplifies management of multiple traffic flows over a single network link. Supports different classes of service, enabling both lossless and classic Ethernet on the same fabric.
Systemwide bandwidth management
It enables consistent and coherent quality-of-service (QoS) management throughout the system.
It provides flexibility to bundle fabric ports in a PortChannel.
