Cisco UCS 2304 Fabric Extender

The Cisco UCS 2304 Fabric Extender has four 40 Gigabit Ethernet, FCoE-capable, Quad Small Form-Factor Pluggable (QSFP+) ports that connect the blade chassis to the fabric interconnect. Each Cisco UCS 2304 can provide one 40 Gigabit Ethernet ports connected through the midplane to each half-width slot in the chassis, giving it a total eight 40G interfaces to the compute. Typically configured in pairs for redundancy, two fabric extenders provide up to 320 Gbps of I/O to the chassis.

Additional Information

Performance

  • Hardware forwarding at 960 Gbps
  • Low-latency cut-through design, providing predictable, consistent traffic latency regardless of packet size, traffic pattern, or enabled features

Layer 2

  • Layer 2 VLAN trunks
  • IEEE 802.1Q VLAN encapsulation
  • Support for up to 1024 VLANs and Virtual SANs (VSANs)
  • Support for Data Center VM-FEX architecture
  • Jumbo frames on all ports (up to 9216 bytes)
  • Pause frames (IEEE 802.3x)

QoS

  • Layer 2 IEEE 802.1p (Class of Service [CoS])
  • CoS-based egress queuing
  • Egress strict-priority queuing
  • Egress port-based scheduling: Weighted Round-Robin (WRR)
  • Eight hardware queues per port

High availability

  • Up to two fabric extenders can work in the Cisco UCS 5100 Series Blade Server Chassis
  • Active-active data-plane operation with failover
  • Capability to fail over from one fabric extender to another in the event of a failure
  • Active-passive management-plane operation
  • Support for nonstop management-plane functions; if the active fabric extender fails, the passive fabric extender takes over the chassis management functions

Management

  • Management of fabric extenders integrated into Cisco UCS Manager
  • Capability to manage blade server chassis components such as power supplies, fans, and blades in conjunction with the fabric interconnect
  • Firmware levels between the fabric extender and fabric interconnect always synchronized

Low-Latency, Lossless 40 Gigabit Ethernet Unified Network Fabric

  • PFC (per-priority pause frame support)
  • Data Center Bridging Exchange (DCBX) Protocol
  • IEEE 802.1Qaz: Bandwidth management

Industry standards

  • IEEE 802.1p: CoS prioritization
  • IEEE 802.1Q: VLAN tagging
  • IEEE 802.3: Ethernet
  • IEEE 802.3ad: Link Aggregation Control Protocol (LACP)
  • IEEE 802.3ba: 40 Gigabit Ethernet
  • QSFP+ support
