In today's data centers, virtualization deployments have become common place, and this trend is increasing rapidly with the availability of 10 Gigabit Ethernet servers at attractive prices. The combination of increased adoption of 10 Gigabit Ethernet servers and applications with higher bandwidth requirements is increasing the need for dense 10 and 40 Gigabit Ethernet switching. Moreover, data center architecture is evolving as customers seek to build large-scale nonblocking fabrics to accommodate different applications, creating patterns of heavy east-west and north-south traffic. Leaf and spine layer designs using high-density and low-latency switches lead to a flatter network architecture, allowing connections scaling from hundreds to 10,000 or more servers with high bidirectional bandwidth, and helping ensure a low-latency fabric with a low hop count.

Features and Benefits
The comprehensive feature sets of the Cisco Nexus 6001 platform make it well suited to meet the challenging demands of virtualized and cloud-based deployments. The Cisco Nexus 6001 is designed with the Cisco high-performance ASICs and is an excellent switch for integrating and connecting a virtual environment to the high-performance servers in the data center. The Cisco Nexus 6001 is excellent for ToR deployments such as direct-attach 10 Gigabit Ethernet server-access and fabric extender aggregation deployments and leaf and spine designs to build scalable Cisco Unified Fabric in data centers. This platform can be deployed in the middle of the row (MoR; in server racks) or at the end of the row (EoR; in network racks) in the data center.
The Cisco Nexus 6001 provides investment protection by allowing the same ports to be used as either Ethernet or FCoE. The switch also provides a high-density option in a 1RU form factor for ToR, MoR, and EoR deployment options. The combination of high port density, lossless Ethernet, wire-speed performance, and very low latency makes the switch well suited to meet the growing demands in the data center with a common Ethernet-based fabric in physical and virtual data center deployments. The Cisco Nexus 6001 delivers scalable performance, intelligence, and a broad set of features to address the needs of data center networks.
Here are some of the primary features of the Cisco Nexus 6001:
• Optimized for virtualization and cloud deployments: The data center today must meet the demands of virtualization and cloud-based computing. High-performance servers deployed in the cloud can support many more virtual machines and workloads than ever before. The requirement to deploy new servers on demand puts additional strain on the network fabric. The Cisco Nexus 6001 addresses this challenge by providing scalability and performance, making it an excellent platform for meeting current and future needs.
• Density and resilience: Built for today's data centers, the switches are designed just like the servers they support. Ports and power connections are at the rear, close to server ports, helping keep cable lengths as short and efficient as possible and delivering to rack servers benefits traditionally offered only on blade servers. Hot-swappable power and fan modules can be accessed from the front panel, where status lights offer an at-a-glance view of switch operation. Front-to-back or back-to-front cooling is consistent with server designs, supporting efficient data center hot- and cold-aisle designs. Serviceability is enhanced with all customer-replaceable units accessible from the front panel.
• Energy efficiency: The Cisco Nexus 6001 helps data centers operate within their space, power, and cooling parameters while reducing their carbon footprints. The switch power supplies are also capable of maintaining 90 percent efficiency at load conditions of as low as 25 percent utilization. This capability allows the switch to make efficient use of power while still being appropriately sized to support the conditions of a full system load.
• Low latency: The Cisco Nexus 6001 with cut-through switching supports approximately 1 microsecond of port-to-port latency for any packet size with features enabled.
• Intelligent Cisco Switched Port Analyzer (SPAN) and Encapsulated SPAN (ERSPAN): SPAN and ERSPAN can be used for troubleshooting and robust monitoring of traffic. The SPAN and ERSPAN capabilities in the Cisco Nexus 6001 are nondisruptive, with only extra bandwidth capacity used for SPAN and ERSPAN traffic. SPAN and ERSPAN traffic is categorized as best effort, and in the event of link congestion, SPAN and ERSPAN traffic is dropped first. Enhancements include more efficient allocation of bandwidth to SPAN and ERSPAN traffic whereby any fabric bandwidth not used for data traffic can be allocated to SPAN or ERSPAN traffic. The switch can support up to 31 line-rate SPAN and ERSPAN sessions.
• Flexible buffer management: The Cisco Nexus 6001 supports a 25-MB packet buffer shared by every 3 ports of 40 Gigabit Ethernet or every 12 ports of 10 Gigabit Ethernet. Of the 25-MB buffer, 16 MB are used for ingress and 9 MB are used for egress buffering. The Cisco Nexus 6001 supports allocation of the buffer as shared or dedicated or shared plus dedicated. The flexible buffer management capability on the Cisco Nexus 6001 allows dynamic tuning of the shared and dedicated buffer size in the event of congestion.
• Multicast enhancements: The Cisco Nexus 6001 supports line-rate Layer 2 and 3 multicast throughput for all frame sizes. The Cisco Nexus 6001 offers optimized multicast replication through the fabric and at the egress point. The large buffers allow absorption of bursty traffic. Support is provided for 32,000 multicast routes and for Internet Group Management Protocol (IGMP) snooping tables in hardware. Multicast enhancements include flow-based hashing for multicast traffic over a PortChannel and enhanced Bidirectional Protocol-Independent Multicast (Bidir-PIM) support. The switch also supports IP-based forwarding for IGMP snooping.
The Cisco Nexus 6001 supports a number of application scenarios, making the switches a versatile data center option.
• Cisco Fabric Extender Technology (FEX Technology) enables customers to build a single, modular fabric that extends from Cisco Nexus switches, to Cisco Unified Computing System™ (Cisco UCS®) servers, to adapters (Cisco Adapter FEX), and to virtual machines (Cisco Data Center VM-FEX). The Cisco FEX technology is based on the emerging standard IEEE 802.1br. Designing the network using Cisco FEX technology provides flexibility, reduced cabling infrastructure, and a single point of management, helping customers scale their networks. Cisco Nexus 2200 platform fabric extenders can be single or dual connected (using enhanced virtual PortChannel [vPC+] technology) to two upstream Cisco Nexus 6001 Switches. Servers or end hosts can connect to single or dual Cisco Nexus 2200 platform fabric extenders using network interface card (NIC) teaming when the parent Cisco Nexus 6001 has vPC+ enabled.
Following are some common Cisco Nexus 2000 and 6000 Series deployment options.
• Rack servers with 100 Megabit Ethernet, Gigabit Ethernet, or 10 Gigabit Ethernet NICs; the fabric extender can be physically located at the top of the rack, and the Cisco Nexus 6000 Series Switch can reside in the middle or at the end of the row, or the fabric extender and the Cisco Nexus 6000 Series Switch can both reside in the middle or at the end of the row.
• Mixed Gigabit Ethernet and 10 Gigabit Ethernet environments in which rack servers are running at either speed in the same rack or in adjacent racks.
• 10 Gigabit Ethernet and FCoE deployments using servers with converged network adapters (CNAs) for unified fabric environments with the Cisco Nexus 2232PP 10GE Fabric Extender.
• 1/10GBASE-T server connectivity with ease of migration from 1 to 10GBASE-T and effective reuse of structured cabling.
• Gigabit Ethernet and 10 Gigabit Ethernet blade servers with pass-through blades.
In addition to the fabric extender deployment options already mentioned, the Cisco Nexus 6001 with high-density 10 and 40 Gigabit Ethernet support provides unique value as a high-density fabric extender aggregation platform. Some sample scenarios are listed here:
• In conjunction with the Cisco Nexus 2248PQ 10GE Fabric Extender, the Cisco Nexus 6001 can be used as a high-density 10 Gigabit Ethernet switching system, consolidating more than 576 10 Gigabit Ethernet connections in a single management plane.
• In conjunction with the Cisco Nexus 2232PP 10GE Fabric Extender, the Cisco Nexus 6001 can be used as a high-density 10 Gigabit Ethernet switching system, consolidating up to 1536 10 Gigabit Ethernet connections in a single management plane.
• A variety of blade fabric extender options can be aggregated into a Cisco Nexus 6001 using 10 Gigabit Ethernet, providing a single point of management for blade server deployments.
• In conjunction with the Cisco Nexus 2248TP GE Fabric Extender, the Cisco Nexus 6001 can be used as a high-density 1 Gigabit Ethernet switching system, consolidating more than 1152 Gigabit Ethernet connections in a single management plane.
Table 4 lists the fabric extenders that are supported with the Cisco Nexus 6001. Please refer to the Cisco Nexus 2200 platform data sheets and release notes for more information about the products.
16x 10 G BASE-KR internal host interfaces and 8 10 Gigabit Ethernet fabric interfaces (SFP+) Network Interfaces
Large-Scale Fabric (Layer 2 and 3): Leaf and Spine Architecture
Data center designs are evolving, with customers seeking to build large-scale nonblocking fabrics to accommodate different applications, creating patterns of heavy east-west and north-south traffic. The Cisco Nexus 6001 is well suited as a leaf or spine node in a Layer 2 or 3 fabric design. Leaf and spine layer designs using high-density and low-latency switches lead to flatter network architecture, allowing connections scaling from hundreds to more than 10,000 servers with high bidirectional bandwidth, and helping ensure low-latency fabric with a low hop count. The spine switches create a nonblocking, low-latency fabric, forwarding packets between leafs. The leaf switches provide connectivity to servers. Use of a highly meshed architecture helps ensure the highest possible network availability with little impact on customer traffic in the event of a failure. The Cisco Nexus 6001 can be deployed as a Layer 2 or Layer 3 spine or leaf switch, providing a high degree of design flexibility.
Cisco Unified Fabric combines data center and storage networks to deliver a single high-performance, highly available, and scalable network. With the Cisco Nexus 6001, Cisco can support end-to-end data center convergence, from the server to storage, by delivering multihop FCoE capability in the data center. The FCoE capability complements the existing FCoE function on the Cisco Nexus 5500 switch platform. With this broad selection of standards-based FCoE switches, Cisco provides unified fabric support to both the access and core network layers, supporting all storage traffic (FCoE, Small Computer System Interface over IP [iSCSI], and network-attached storage [NAS]) over simplified infrastructure based on lossless 10 and 40 Gigabit Ethernet. The Cisco Nexus 6000 Series Switches are the industry's first to provide 40-Gbps FCoE support, surpassing the 16-Gbps Fibre Channel capability.
The Cisco Nexus 6001 can be deployed as a high-density Small Form-Factor (SFF) access-layer switch to consolidate a large number of 10 Gigabit Ethernet servers in deployments that call for only a small number of hops from the server to the upstream network to reduce latency. The Cisco Nexus 6001 has a high density of 10 Gigabit Ethernet ports per rack unit, approximately 1 microsecond of latency port to port for any packet size, integrated line-rate Layer 2 and 3 features, scalability, and integrated data analytics with programmability. It addresses the needs of high-performance computing (HPC) and high-frequency trading (HFT) environments, for which InfiniBand solutions lack management visibility and high performance of bulk data transfers across traditional applications.
The capability of the Cisco Nexus 6001 to function in all these capacities helps protect investments in the data center with a deployment model in which additional features can be enabled as they are needed.

Cisco NX-OS meets Ethernet and storage networking requirements, providing a robust and comprehensive feature set that can meet the demanding requirements of virtualization and automation in present and future data centers. Cisco's enhanced fabric solution allows the transparent integration of the virtual and physical devices on a unified network. In addition, users can use the comprehensive Cisco NX-OS service set to create unique innovations for customized solutions. With its MIBs, native XML interface, and command-line interface (CLI) like that of Cisco IOS® Software, Cisco NX-OS provides drastically simplified management for the devices in which it runs.
Cisco NX-OS Software Features and Benefits
• Software compatibility: Cisco NX-OS Software Release 6.0 interoperates with Cisco products running any variant of the Cisco IOS Software operating system. Cisco NX-OS 6.0 also interoperates with any networking OS that conforms to the networking standards listed as supported in this data sheet.
• Common software throughout the data center: Cisco NX-OS simplifies the data center operating environment and provides a unified OS designed to run all areas of the data center network, including the LAN, SAN, and Layer 4 to 7 network services.
• Modular software design: Cisco NX-OS is designed to support distributed multithreaded processing on symmetric multiprocessors (SMPs), multicore CPUs, and distributed line-card processors. Computationally intensive tasks, such as hardware table programming, can be offloaded to dedicated processors distributed across the line cards. Cisco NX-OS modular processes are instantiated on demand, each in a separate protected memory space. Thus, processes are started and system resources allocated only when a feature is enabled. The modular processes are governed by a real-time preemptive scheduler that helps ensure the timely processing of critical functions.
• Enhanced virtual PortChannel: The vPC feature allows one end of a PortChannel to be split across a pair of Cisco Nexus 6000 Series Switches. vPC provides Layer 2 multipathing through the elimination of Spanning Tree Protocol blocked ports in dual-homed connections. vPC enables fully used bisectional bandwidth and simplified Layer 2 logical topologies without the need to change the existing management and deployment models. The vPC feature has been enhanced so that edge devices can connect to the Cisco Nexus 2000 Series using vPC, and the Cisco Nexus 2000 Series can connect to the Cisco Nexus 6000 Series using vPC at same time.
• Cisco FabricPath: Cisco FabricPath provides the simplicity and fabric efficiency to easily deploy new virtualized services in a cloud-based environment. New virtual and physical servers can be added to the network with the simplicity and mobility of the Layer 2 network without the deficiencies of traditional Spanning Tree Protocol.
Cisco FabricPath is a set of multipath Ethernet technologies that combines the reliability and scalability benefits of Layer 3 routing with the flexibility of Layer 2 networks, enabling IT to build massively scalable data centers. Cisco FabricPath offers a topology-based Layer 2 routing mechanism that provides an equal-cost multipath (ECMP) forwarding model. Cisco FabricPath implements an enhancement that solves the MAC address table scalability problem characteristic of switched Layer 2 networks. Furthermore, Cisco FabricPath supports vPC+, a technology similar to vPC that allows redundant interconnection of the existing Ethernet infrastructure to Cisco FabricPath without using Spanning Tree Protocol. Benefits introduced by the Cisco FabricPath technology include:
– Operation simplicity: Cisco FabricPath embeds an autodiscovery mechanism that does not require any additional platform configuration. By offering Layer 2 connectivity, the "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 ECMP routing, Cisco FabricPath helps prevent bandwidth bottlenecks and allows organizations to add capacity dynamically, without network disruption.
– Multiple-topology support. Cisco FabricPath supports two distinct topologies that provide VLAN localization and reuse in the network.
• Automation: Cisco NX-OS provides the intelligence and flexibility to support device-aware power-on provisioning, enabling transparent autoconfiguration of devices. Users can create custom Python scripts that are specific to their environments.
• Programmability: Cisco NX-OS enables users to innovate using Cisco onePK. Customers can create host-based applications using the comprehensive service set available in Cisco NX-OS.
• Programmatic XML interface: Based on the NETCONF industry standard, the Cisco NX-OS XML interface provides a consistent API for devices, enabling rapid development and creation of tools to enhance the network.
• Simple Network Management Protocol (SNMP): Cisco NX-OS complies with SNMP Versions 1, 2, and 3. An extensive collection of MIBs is supported.
