    Product Overview

    The Cisco Nexus® 7000 Enhanced F2-Series 48-Port 1 and 10GBASE-T Ethernet Copper Module (referred to as the Cisco Nexus 7000 F2e Copper Module in this document) offers outstanding flexibility and wire-rate performance on each port. The module enables the deployment of high-density, low-latency, scalable data center architectures based on the IEEE 802.3an standard, best known as 10GBASE-T.

    The Cisco Nexus 7000 Series Switches provide the foundation of the Cisco® Unified Fabric. They are a modular data center-class product line designed for highly scalable 10 Gigabit Ethernet networks. The fabric architecture scales beyond 15 terabits per second (Tbps) and is designed to support future 40 and 100 Gigabit Ethernet interfaces. To meet the requirements of the most mission-critical network environments, the switches deliver continuous system operations and virtualized services. The Cisco Nexus 7000 Switches is powered by the proven Cisco NX-OS Software operating system, with enhanced features to deliver real-time system upgrades with exceptional manageability and serviceability. Its innovative unified fabric design is purpose built to support consolidation of IP and storage networks on a single lossless Ethernet fabric.

    10GBASE-T Solution Benefits

    The 10GBASE-T solution for the Cisco Nexus 7000 Switches delivers high-performance, cost-effective, and efficient next-generation RJ-45-based server connectivity. Based on the IEEE 802.3an standard, 10GBASE-T is a crucial technology for designing next-generation data center architectures with:

       Reduced deployment costs through integrated 10 Gigabit Ethernet, lower cable costs, and flexible cable lengths

       Simplified transition to 10 Gigabit Ethernet through backward compatibility with existing 1 Gigabit Ethernet networks

       Preserved user experience and expertise of previous generations of BASE-T

       New consolidation usage models to reduce total cost of ownership (TCO) with advanced I/O virtualization and unified networking

    Module Features and Benefits

    The Cisco Nexus 7000 F2e Copper Module (Figure 1) is a low-latency, high-performance, high-density 10GBASE-T Ethernet module designed for mission-critical data center networks. The Cisco Nexus 7000 F2e Copper Module provides the highest density of wire-rate 10GBASE-T Ethernet ports on the market, with up to 768 wire-rate 10GBASE-T Ethernet ports in a single system, through the use of the Cisco Nexus 7000 18-Slot Switch chassis (Table 1).

    The Cisco Nexus 7000 F2e-Series Copper Module is built with switch-on-chip (SoC) architecture, in which a single application-specific integrated circuit (ASIC) implements all the module functions, including ingress buffering, forwarding lookup operations, access control lists (ACLs), quality-of-service (QoS) tables, fabric interfaces, and virtual output queuing (VOQ). Each SoC manages four front-panel interfaces. This type of design increases performance while lowering the power and cooling requirements of the module.

    Each port of the Cisco Nexus 7000 F2e Copper Module can also be used at 1 Gigabit Ethernet speed, allowing IT departments to migrate their servers base to 10GBASE-T based on the specific needs of their networks. Excellent for end-of-row (EoR) and middle-of-row (MoR) designs, the Cisco Nexus 7000 F2e Copper Module provides flexibility and scalability and a comprehensive feature set.

    The Cisco Nexus 7000 F2e Copper Module offers customers low 10GBASE-T power consumption, with less than 9 watts (W) per port for typical deployment scenarios. The power efficiency of the module is further improved by enabling the Energy-Efficient Ethernet function.

    A standard developed by the IEEE 802.3az task force, Energy-Efficient Ethernet (Figure 2) is a set of enhancements that enables less power consumption in response to changes in network demand. By sending a low-power-idle (LPI) indication signal for a specified time, the transmit chips in the system can be turned off. LPI is sent periodically to refresh the sleep mode. When there is data to transmit, a normal idle signal is sent to wake the transmit system before data is sent. The data link is considered to be always operational because the receive signal circuit remains active even when the transmit path is in sleep mode.

    By enabling Energy-Efficient Ethernet the Cisco Nexus 7000 F2e Copper Module, organizations can achieve an additional 15 percent power reduction in typical deployments.

    The module’s power efficiency is achieved without compromising its capabilities. Besides the traditional Layer 2 and Layer 3 forwarding capabilities, the Cisco Nexus 7000 F2e Copper Module delivers Cisco FabricPath technology based on IETF TRILL. Cisco FabricPath consists of a set of multipath Ethernet technologies, combining the reliability and scalability benefits of Layer 3 routing with the flexibility and “plug-and-play” aspects of Layer 2 Ethernet networks.

    With Cisco FabricPath, organizations can now build resilient and flexible Layer 2 networks, no longer relying on Spanning Tree Protocol and its inherent bisectional bandwidth limitations.

    The benefits of Cisco FabricPath include:

       Operational simplicity: Cisco FabricPath embeds an autodiscovery mechanism that does not require any additional platform configuration. By offering Layer 2 connectivity, this “VLAN anywhere” characteristic simplifies provisioning and offers workload flexibility across the network.

       High resiliency and performance: Because Cisco FabricPath is a Layer 2 routed protocol, it offers stability, scalability, and optimized resiliency along with network failure containment.

       Massively scalable fabric: By building a forwarding model on 16-way equal-cost multipath (ECMP), Cisco FabricPath helps prevent bandwidth bottlenecks and allows capacity to be added dynamically, without network disruption.

    The Cisco Nexus 7000 F2e-Series Copper Module offers exceptional security with integrated hardware support for Cisco TrustSec® technology, including line-rate data confidentiality, data integrity, and ACL processing for security group tags (SGTs). Data confidentiality and integrity conforming to the IEEE MAC security standard (IEEE 802.1AE MACsec) is supported on all ports with Advanced Encryption Standard (AES) cipher, using a 128-bit key[1]. New security ACLs are enhanced through hardware support for Cisco metadata headers capable of carrying SGTs. Security group ACLs (SGACLs) use SGT information to provide hardware-based enforcement of security policies, removing dependencies on IP addresses, thus improving scalability and simplifying manageability.

    Table 2 summarizes the features and benefits of the Cisco Nexus 7000 F2e Copper Module.

    Table 2.       Features and Benefits



    Support for 1 and 10 Gigabit Ethernet

    Each port can be used at 1 or 10GBASE-T Ethernet speed, allowing IT departments to migrate to 10GBASE-T for their server connectivity according to the unique requirements of their networks.

    Comprehensive Layer 2 and Layer 3 capabilities

    The comprehensive set of Layer 2 and Layer 3 functions makes this module excellent for data center networks.

    Virtual device context (VDC)

    The Cisco VDC feature helps enable the virtualization of a single physical device in one or more logical devices. Each of the provisioned logical devices is configured and managed as if it were a separate physical device[2].

    Cisco FabricPath technology based on IETF TRILL

    Cisco FabricPath uses routing principles in the data plane and control plane to bring reliability and scalability to transparent bridging while maintaining flexibility and ease of use.

    Efficient power use

    Power consumption is exceptionally low, typically less than 9W per port. By enabling Energy-Efficient Ethernet, organizations can achieve an additional 15% power reduction in typical configurations.

    Virtual output queuing (VOQ) with centralized arbitration

    This feature enables fairness when one or more destinations is congested and support for lossless unified fabric.

    Load sharing across all fabric modules

    Through the high-availability design, bandwidth is shared across all fabric modules simultaneously for optimal performance.

    Online insertion and removal (OIR)

    Hot insertion and removal is supported for continuous system operation.

    Identification (ID) LED

    Through the beacon feature, administrators can clearly identify the module for a service condition; ports on the I/O module can send beacons as well.
