The Cisco UCS 6324 Fabric Interconnect
Fabric Interconnect provides the management, LAN, and storage connectivity for the Cisco UCS 5108 Blade Server Chassis and direct-connect rack-mount servers. It provides the same full-featured Cisco UCS management capabilities and XML API as the full-scale Cisco UCS solution in addition to integrating with Cisco UCS Central Software and Cisco UCS Director.

The Cisco UCS 6324 Fabric Interconnect extends the Cisco UCS architecture into environments with requirements for smaller domains. Providing the same unified server and networking capabilities as in the full-scale Cisco UCS solution, the Cisco UCS 6324 Fabric Interconnect embeds the connectivity within the Cisco UCS 5108 Blade Server Chassis to provide a smaller domain of up to 20 servers

The Cisco UCS 6324 Fabric Interconnect is a 10 Gigabit Ethernet, FCoE, and Fibre Channel switch offering up to 500-Gbps throughput and up to four unified ports and one scalability port.

• Cisco UCS 6324 Fabric Interconnect: Layer 2 hardware forwarding at 500 Gbps or 375 million packets per second (mpps)
• MAC address table entries: 20,000
• Low-latency cut-through design: Provides predictable, consistent traffic latency regardless of packet size, traffic pattern, or enabled features

• Layer 2 interconnect ports and VLAN trunks
• IEEE 802.1Q VLAN encapsulation
• Support for up to 512 VLANs and 32 Virtual SANs (VSANs) per interconnect
• Internet Group Management Protocol (IGMP) Versions 1, 2, and 3 snooping
• Link Aggregation Control Protocol (LACP): IEEE 802.3ad
• Advanced Ether Channel hashing based on Layer 2, 3, and 4 information
• Jumbo frames on all ports (up to 9216 bytes)
• Pause frames (IEEE 802.3x)

• Layer 2 IEEE 802.1p (Class of Service [CoS])
• CoS trust
• CoS-based egress queuing
• Egress port-based scheduling: Deficit Weighted Round-Robin (DWRR)
• 16 hardware queues (8 each for unicast and multicast)

• Two Cisco UCS 6324 Fabric Interconnect Fabric Interconnects can be clustered together within the chassis to provide a highly available interconnect system
• Firmware upgrades can be performed on each fabric interconnect independently, allowing server connectivity to be maintained while firmware upgrades are completed

• Interconnect management using redundant 10/100/1000-Mbps management or console ports
• All management provided through Cisco UCS Manager; please refer to the Cisco UCS Manager data sheet for more information about management interfaces

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

• All 4 SFP ports configurable as 1/10 Gigabit Ethernet or 2/4/8-Gbps Fibre Channel

• IEEE 802.1p: CoS prioritization
  IEEE 802.1Q: VLAN tagging
  
• IEEE 802.3: Ethernet
• IEEE 802.3ad: LACP
• IEEE 802.3ae: 10 Gigabit Ethernet
• IEEE 802.1AB LLDP
