The Cisco Nexus 2000 Series architecture provides the following benefits:
● Architecture flexibility: A common, scalable, and adaptive architecture across data center racks and points of delivery (PoDs)[1] supports various server options, connectivity options, physical topologies, and evolving needs.
● Highly scalable server access: 1 and 10 Gigabit Ethernet server access is scalable, with no reliance on Spanning Tree Protocol.
● Simplified operations: One single point of management and policy enforcement using upstream Cisco Nexus switches eases the commissioning and decommissioning of server racks through zero-touch installation and automatic configuration of fabric extenders.
● Increased business benefits: Consolidation, cabling reduction, rack-space reduction, reduced power and cooling, investment protection through feature inheritance from the parent switch, and the capability to add functions without the need for a major equipment upgrade of server-attached infrastructure all contribute to reduced operating expenses (OpEx) and capital expenditures (CapEx).
The Cisco Nexus 2000 Series design aligns with that of servers. It offers front-to-back cooling, compatible with data center hot-aisle and cold-aisle designs, all switch ports at the rear of the unit in close proximity to server ports, and all user-serviceable components accessible from the front panel. It also offers back-to-front cooling, with switch ports in front of the chassis, aligned with the cold aisle, for optimized cabling in network racks. The Cisco Nexus 2000 Series is built for nonstop operation, with redundant hot-swappable power supplies and a hot-swappable fan tray with redundant fans. Its compact 1-rack-unit (1RU) form factor takes up relatively little space, making it easy to incorporate into rack designs. The fabric extenders are available in several models to provide speed, connectivity, and port-density options.
Cisco Nexus 2000 Series Fabric Extenders connect to a parent Cisco Nexus switch through their fabric links using CX1 copper cable, short-reach or long-reach optics, and the cost-effective Cisco Fabric Extender Transceivers. Fabric Extender Transceivers are optical transceivers that provide a highly cost-effective solution for connecting the fabric extender to its parent switch over OM3 or OM4 multimode fiber.
The fabric extenders behave like remote line cards for a parent Cisco Nexus 5000, 6000, or 7000 Series Switch. Working in conjunction with Cisco Nexus switches, the fabric extenders extend the capabilities and benefits offered by the parent Cisco Nexus switch while providing flexible, scalable, and cost-effective server access.
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 10Gigabit 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, as shown in Table 2.
● 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.
● Consolidation: The Cisco Nexus 2000 Series protects an organization’s investment into the future, supporting evolving data center needs by providing an easy migration path to low-latency 10 Gigabit Ethernet, high-performance computing (HPC), virtual machine-aware networks. In addition, the combination of the Cisco Nexus 5000 or 6000 Series and Cisco Nexus 2232PP or 2248PQ provides a unified network fabric that supports LAN and SAN consolidation. Another benefit of the Cisco Nexus 2000 Series architecture is the capability to collapse data center access and aggregation layers into one single layer.
● 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.
● 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.
Cisco Nexus 2000 Series Deployment Scenarios
The fabric extenders can be used in the following deployment scenarios:
● Rack servers with 100 Megabit Ethernet, 1 Gigabit Ethernet, or 10 Gigabit Ethernet network interface cards (NICs); the fabric extender can be physically located at the top of the rack and the Cisco Nexus parent switch can reside in the middle or at the end of the row, or the fabric extender and the Cisco Nexus parent switch can both reside at the end or middle of the row
● 10 Gigabit Ethernet and FCoE deployments, using servers with converged network adapters (CNAs) for unified fabric environments with the Cisco Nexus 2232PP, 2248PQ, and 2232TM-E.
● 1/10GBASE-T server connectivity with ease of migration from 1 to 10GBASE-T and effective reuse of structured cabling
● Server racks with integrated lights-out (iLO) management, with 100 Megabit Ethernet or 1 Gigabit Ethernet management and iLO interfaces
● 1 and 10 Gigabit Ethernet blade servers with pass-through blades
● Low-latency, high-performance computing environments
● Virtualized access

The Cisco Nexus 2000 Series can be used in conjunction with a Cisco Nexus parent switch in four main design scenarios (shown in Figure 7):
● Cisco Nexus 2000 Series Fabric Extenders single-connected to one upstream Cisco Nexus 5000, 6000, or 7000 Series Switch: In this deployment scenario, access-layer redundancy is achieved through redundant server connections to two upstream distributed modular systems using vPC (Cisco Nexus 5000, 6000, or 7000 Series) or server NIC teaming to two Cisco Nexus 2000 Series Fabric Extenders.
● Cisco Nexus 2000 Series Fabric Extenders dual-connected to two upstream Cisco Nexus 5000, 6000, or 7000 Series Switches (vPC): In this deployment scenario, access-layer redundancy is achieved through a combination of Cisco Nexus 2000 Series Fabric Extenders dual-connected to an upstream parent switch and server NIC teaming.
● Enhanced vPC (EvPC): In this deployment scenario, access-layer redundancy is achieved in two ways: through redundant connections between the Cisco Nexus 2000 Fabric Extenders and the Cisco Nexus parent switches using vPC, and through redundant server connections to two fabric extenders using vPC and active-active server NIC teaming. This scenario is supported only with the Cisco Nexus 5000 or 6000 Series Switches used as upstream switches. This scenario is not currently supported with the Cisco Nexus 7000 Series Switches.
● vPC+: In this deployment scenario, access-layer redundancy is achieved through server vPC, fabric extender vPC, and EvPC. In addition, a vPC+ domain allows the Cisco Nexus parent switch and the fabric extenders to be viewed as a single virtual switch in a Cisco FabricPath network.
