Description
Cisco IOM 2304V2XP I/O Module (4 External, 8 Internal 40Gb Ports) 40GB PORTS
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.

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)

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
