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 abric extender architecture to provide a highly scalable unified server-access platform across a range of 100 Megabit Ethernet, 1 and 10 Gigabit Ethernet, unified fabric, copper and fiber connectivity, and rack and blade server environments. The platform is well suited to support today’s traditional 1 Gigabit Ethernet environments while allowing transparent migration to 10 Gigabit Ethernet, virtual machine-aware unified fabric technologies.
The Cisco Nexus 2000 Series Fabric Extenders behave like 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 switch together forming a distributed modular system.Architecture Flexibility
● Unified server access architecture: The Cisco Nexus 2000 Series offers a highly cost-effective access-layer architecture for 100 Megabit Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, mixed Gigabit Ethernet, and 10 Gigabit Ethernet servers; Ethernet or unified fabrics; physical or virtual servers; and rack or blade server environments.
● Flexible physical topologies: The Cisco Nexus 2000 Series architecture allows the Layer 1 and 2 topologies to be decoupled, therefore providing flexibility in physical architecture designs, including ToR, middle-of-row (MoR), and EoR deployments, while allowing quick expansion of network capacity and remote line-card portability across multiple parent switches. It is also space optimized for all these architectures.
Highly Scalable Access Layer
Today’s data centers must have massive scalability to manage the combination of an increasing number of servers and a higher demand for bandwidth from each server. The Cisco Nexus 2000 Series increases the scalability of the access layer to accommodate both sets of demands without increasing management points within the network.
● Massive scalability: A deployment of Cisco Nexus 2000 Series Fabric Extenders connected to a Cisco Nexus 5000, 6000, or 7000 Series Switch supports highly scalable 1 and 10 Gigabit Ethernet environments.
● Layer 2 scalability: Reliance on Spanning Tree Protocol is eliminated between the fabric extender and the parent switch, thus enabling a large, multipath, loop-free topology. Use of a single management entity to support a large server domain allows policy to be enforced more efficiently and enhances Layer 2 data center access scalability. Use of the virtual PortChannel (vPC) feature also allows fast convergence and effective use of bandwidth in Layer 2 environments.
Simplified Operations
● Single point of management: The Cisco Nexus 2000 Series Fabric Extenders are remote line cards for a Cisco Nexus parent switch. All device configurations are managed on the parent switch, and configuration information is downloaded to the fabric extender using in-band communication.
● Software maintenance simplification: The Cisco Nexus 2000 Series software is embedded in the Cisco Nexus parent switch software. The fabric extender is a ready-to-use device that automatically downloads the software image from the parent switch in the same way that a line card downloads software from the supervisor engine in a modular chassis. In-Service Software Upgrade (ISSU) on the fabric extenders provides the capability to perform transparent software upgrades, reducing downtime and allowing customers to integrate the newest features and functions with little or no negative effect on network operation for Ethernet, storage, and converged network environments.
● Switch feature consistency across a large number of servers: The Cisco Nexus 2000 Series forwards all traffic to the parent Cisco Nexus switch over 10 Gigabit Ethernet fabric uplinks. Passing all traffic to the parent switch allows traffic to be shaped according to policies established on the parent switch with a single point of management. Standardizing on the Cisco Nexus switches allows data centers to support the same switch features across the entire access layer with a single point of management.
● Tenfold reduction in management points: The number of management points is significantly less than when discrete switches are used at the top of the rack. A traditional 12-rack design using a discrete, redundant pair of Gigabit Ethernet switches at the top of each rack has 24 management points. The equivalent architecture using the Cisco Nexus 2000 Series has only 2 management points: a tenfold reduction in management complexity.
Business Benefits
● Cost-effective 10 Gigabit Ethernet solution: The Cisco Nexus 2000 Series is an excellent platform for migration from 1 Gigabit Ethernet to 10 Gigabit Ethernet. Scalable 10 Gigabit Ethernet provides 10 times the bandwidth for approximately twice the price of Gigabit Ethernet.
● Investment protection: The Cisco Nexus 2000 Series Fabric Extenders can be mixed and matched with a common parent Cisco Nexus switch. New functions can be derived from upstream Cisco Nexus switches, resulting in the capability to add new functions without the need for a major equipment upgrade.
● Rack-space reduction: The Cisco Nexus 2000 Series consists of 1RU fabric extenders. The fabric extenders are not physically constrained by the position of the Cisco Nexus parent switch in the physical topology and are attached to the upstream Cisco Nexus switch through fabric links.
● Cabling reduction with optimal intra- and inter-rack cabling options: The Cisco Nexus 2000 Series supports ToR, EoR, and MoR deployment models. Placing the fabric extender at the top of the rack allows the use of short cables from the rack to the servers, reducing cable costs, air dams, complexity, and opportunities for error. The only inter-rack cabling required is for uplinks from the fabric extender to the parent switch. Placing the parent Cisco Nexus switch at the end or middle of a row of racks makes efficient use of powerful switching resources.
● The Cisco Nexus 2000 Series supports an optimal cabling strategy that simplifies network operations and prepares for future technologies:
◦ Short intra-rack runs of copper: Intra-rack cables connecting to Gigabit Ethernet servers can be Category 5e, 6, 6a, or 7 with the Cisco Nexus 2148T, 2224TP, 2248TP, and 2248TP-E fabric extenders. Category 6, 6a, or 7 can connect 10GBASE-T servers to the Cisco Nexus 2232TM and 2232TM-E. Twinax cables connect servers to ToR Cisco Nexus 2232PP fabric extenders. This model allows server racks and PoDs to be preconfigured by server vendors so that they can be rolled into place and put into service upon arrival.
◦ Longer inter-rack horizontal runs of fiber: Cisco Nexus 2000 Series Fabric Extenders in each rack are connected to parent switches that are placed at the end or middle of the row. For long reach between the fabric extender and the parent switch, you can use Fabric Extender Transceiver, SFP+ short-reach (SR), SFP+ long-reach (LR) optics over OM2 or OM3 cables, and QSFP+ optics for 40-Gbps connectivity. Fiber protects investments into the future because it will support upcoming Ethernet standards, including 40 and 100 Gigabit Ethernet. If the distance to the Cisco Nexus 5000, 6000, or 7000 Series Switch is less than 10 meters, you can use Twinax cables (CX1 direct attach). Alternatively, you can use copper cables to reach EoR or MoR 1GBASE-T or 10GBASE-T fabric extenders.
● Effective bandwidth utilization: Today’s data center servers are either single- or dual-homed to the network. However, network designs almost always involve redundant deployment. Through the vPC feature support on the Cisco Nexus 5000, 6000, and 7000 Series, a server can be dually connected to a pair of fabric extenders, or each fabric extender can be connected to a pair of Cisco Nexus 5000, 6000, or 7000 Series Switches, thus giving customers both server and fabric extender connectivity redundancy and providing active-active connectivity with twice the bandwidth utilization as in active-standby or forwarding-blocking configurations.
● Reduced power and cooling needs: Cost-effective 10 Gigabit Ethernet solutions, optimal cabling, device consolidation, rack-space reduction, and efficient bandwidth use all contribute to a significant reduction in power and cooling needs in the data center.

The fabric extenders can be used in the following deployment scenarios:
