Cisco Nexus 2000 Series Fabric Extenders
Product Overview
The Cisco Nexus
®
2000 Series Fabric Extenders comprise a category of data center products designed to simplify
data center access architecture and operations. The Cisco Nexus 2000 Series uses the Cisco
®
Fabric Extender
architecture to provide a highly scalable unified server-access platform across a range of 100 Megabit Ethernet,
Gigabit Ethernet, 10 Gigabit Ethernet, unified fabric, copper and fiber connectivity, rack, and blade server
environments. The platform is ideal to support today’s traditional Gigabit Ethernet while allowing transparent
migration to 10 Gigabit Ethernet, virtual machine-aware unified fabric technologies.
The Cisco Nexus 2000 Series Fabric Extenders behave as remote line cards for a parent Cisco Nexus switch. The
fabric extenders are essentially extensions of the parent Cisco Nexus switch fabric, with the fabric extenders and
the parent Cisco Nexus switch together forming a distributed modular system. This architecture enables physical
topologies with the flexibility and benefits of both top-of-rack (ToR) and end-of-row (EoR) deployments (Figure 1).
Figure 1. Cisco Nexus 2000 Series Fabric Extenders Provide Highly Scalable Unified Server-Access Connectivity
The Cisco Nexus 2000 Series architecture provides the following benefits:
●
Architecture flexibility: Common, scalable, and adaptive architecture across data center racks and points of
delivery (PoDs)

that supports various server options, connectivity options, physical topologies and
evolving needs.
●
Highly scalable server access: Scalable Gigabit and 10 Gigabit Ethernet server access with no reliance on
Spanning Tree.

A PoD is a module or group of network, compute, storage, and application components that work together to deliver a network
service. The PoD is a repeatable pattern, and its components increase the modularity, scalability, and manageability of data
centers.
