The Cisco Nexus 2000 Series Fabric Extenders are a category of data center products that simplify network architecture and operations. These fabric extenders behave like remote line cards for a parent Cisco Nexus switch, extending the capabilities of the parent switch while providing a highly scalable unified server access platform.

The Cisco Nexus 2000 platform supports a flexible unified architecture across 100Mb, 1GbE, and 10GbE servers. It allows for various connectivity options like copper and fiber and supports different physical topologies like top-of-rack, middle-of-row, and end-of-row deployments. Key benefits of the Nexus 2000 architecture include scalability, simplified operations, consolidation, and investment protection. The platform enables transparent migration from 1GbE to 10GbE environments.
