    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, 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. 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: 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 (Figure 2).

    The Cisco Nexus 2000 Series provides two types of ports: ports for end-host attachment (host interfaces) and uplink ports (fabric interfaces). Fabric interfaces, differentiated with a yellow color, are for connectivity to the upstream parent Cisco Nexus switch.

    Table 1 lists the Cisco Nexus 2000 Series Fabric Extenders. Fabric extenders can be mixed and matched to a parent switch to provide connectivity options.

    32 x 1/10GBASE-T host interfaces and uplink modules (8 x 10 Gigabit Ethernet fabric interfaces [SFP+]); FCoE support up to 30m with Category 6a and 7 cables

    The Cisco Nexus 2248TP-E (Figure 3) is a general-purpose 1 Gigabit Ethernet fabric extender with enhancements that target workloads such as large-volume databases, distributed storage, and video editing. Like the Cisco Nexus 2248TP, the Cisco Nexus 2248TP-E supports 48 x 100/1000BASE-T host-facing ports and four 10 Gigabit Ethernet fabric interfaces. It also supports 32-MB shared buffers.

    Figure 3.      Cisco Nexus N2248TP-E

    The Cisco Nexus 2248PQ 10 Gigabit Ethernet fabric extender (Figure 4) is the newest member of the Cisco Nexus fabric extenders. It supports high-density 10 Gigabit Ethernet environments and has 48 x 1 and 10 Gigabit Ethernet SFP+ host ports and 4 QSFP+ fabric ports (16 x 10 Gigabit Ethernet fabric ports). QSFP+ connectivity simplifies cabling while lowering power and solution cost. The Cisco Nexus 2248PQ 10GE Fabric Extender supports FCoE and a set of network technologies known collectively as Data Center Bridging (DCB) that increase the reliability, efficiency, and scalability of Ethernet networks. These features allow support for multiple traffic classes over a lossless Ethernet fabric, thus enabling consolidation of LAN, SAN, and cluster environments.

    Figure 4.      Cisco Nexus N2248PQ

    The Cisco Nexus 2232PP 1 and 10 Gigabit Ethernet fabric extender (Figure 5) is an excellent platform for migration from 1 Gigabit Ethernet to 10 Gigabit Ethernet and unified fabric environments. It supports FCoE and DCB.

    Figure 5.      Cisco Nexus N2232PP

    The Cisco Nexus 2232TM-E fabric extender (Figure 6) supports scalable 1/10GBASE-T environments, ease of migration from 1GBASE-T to 10GBASE-T, and effective reuse of existing structured cabling. It comes with an uplink module that supports eight 10 Gigabit Ethernet fabric interfaces. It is a superset of the Cisco Nexus 2232TM with the latest generation of 10GBASE-T PHY, enabling lower power and improved bit error rate (BER). The Cisco Nexus 2232TM-E supports DCB and LAN and SAN consolidation. FCoE support distances of up to 30 meters with Category 6a and 7 cables from the adapter to the fabric extender.

    Figure 6.      Cisco Nexus N2232TM-E

    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
