Cisco UCS 6324 Fabric Interconnect Data Sheet

 

Cisco Unified Computing System overview

The Cisco Unified Computing System^™ (Cisco UCS^®) is a next-generation data center platform that unites computing, networking, storage access, and virtualization resources into a cohesive system designed to reduce Total Cost of Ownership (TCO) and increase business agility. The system integrates a low-latency, lossless 10 Gigabit Ethernet unified network fabric with enterprise-class, x86-architecture servers. The system is an integrated, scalable, multichassis platform in which all resources participate in a unified management domain (Figure 1).

The Cisco Unified Computing System is a Highly Available Cohesive Architecture

Product overview

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 (Figure 2).

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 (Figure 2).

Full Scale Cisco UCS 6324 Fabric Interconnect solution

From a networking perspective, the Cisco UCS 6324 Fabric Interconnect uses a cut-through architecture, supporting deterministic, low-latency, line-rate 10 Gigabit Ethernet on all ports, switching capacity of up to 500 Gbps, and 80-Gbps uplink bandwidth for each chassis, independent of packet size and enabled services. Sixteen 10-Gbps links connect to the servers, providing a 20-Gbps link from each Cisco UCS 6324 Fabric Interconnect to each server. The product family supports Cisco^® low-latency, lossless 10 Gigabit Ethernet¹ unified network fabric capabilities, which increase the reliability, efficiency, and scalability of Ethernet networks. The fabric interconnect supports multiple traffic classes over a lossless Ethernet fabric from the blade through the fabric interconnect. Significant TCO savings come from a Fibre Channel over Ethernet (FCoE)-optimized server design in which Network Interface Cards (NICs), Host Bus Adapters (HBAs), cables, and switches can be consolidated.

Cisco UCS Management Architecture

Unified Fabric with FCoE: I/O consolidation

The Cisco UCS 6324 Fabric Interconnect is built to consolidate LAN and storage traffic onto a single unified fabric, eliminating the Capital Expenditures (CapEx) and Operating Expenses (OpEx) associated with multiple parallel networks, different types of adapter cards, switching infrastructure, and cabling within racks. The unified ports allow the fabric interconnect to support direct connections from Cisco UCS to Fibre Channel, FCoE, and Small Computer System Interface over IP (iSCSI) storage devices.

Cisco UCS Manager

The Cisco UCS 6324 Fabric Interconnect hosts and runs Cisco UCS Manager in a highly available configuration, enabling the fabric interconnects to fully manage all Cisco UCS elements. The Cisco UCS 6324 Fabric Interconnect Fabric Interconnects support out-of-band management through a dedicated 10/100/1000-Mbps Ethernet management port. Cisco UCS Manager typically is deployed in a clustered active-passive configuration on with two UCS 6324 Fabric Interconnects connected through the cluster interconnect built into the chassis.

Optimization for virtualization

For virtualized environments, the Cisco UCS 6324 Fabric Interconnect supports Cisco virtualization-aware networking and Cisco Data Center Virtual Machine Fabric Extender (VM-FEX) architecture. Cisco Data Center VM-FEX allows the fabric interconnects to provide policy-based virtual machine connectivity, with network properties moving with the virtual machine and a consistent operational model for both physical and virtual environments.

Cisco UCS 6324 Fabric Interconnect

The Cisco UCS 6324 Fabric Interconnect Fabric Interconnect (Figure 4) 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.
