Features and Benefits

The following are some of the primary features of the Cisco Nexus 6001 Switch:

●   Optimization for virtualization and cloud deployments: Today, 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 Switch 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 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 Switch 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 Switch are nondisruptive, with only extra bandwidth capacity used for SPAN and ERSPAN traffic. 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 Switch supports a 25-MB packet buffer shared by every 3 ports of 40 Gigabit Ethernet or every 12 ports of 10 Gigabit Ethernet. The flexible buffer management capability on the Cisco Nexus 6001 Switch allows dynamic tuning of the shared and dedicated buffer size in the event of congestion.

●   Multicast enhancements: The Cisco Nexus 6001 Switch supports line-rate Layer 2 and 3 multicast throughput for all frame sizes. It offers optimized multicast replication through the fabric and at the egress point. 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.

Applications

The Cisco Nexus 6001 Switch supports a number of application scenarios, making it a versatile data center option.

Fabric Extender Architecture: High-Density Fabric Extender Aggregator

Cisco Fabric Extender Technology (FEX Technology) enables you 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. When Nexus 6001 Switches are part of a fabric that includes Cisco Nexus 2200 platforms, use the Cisco Nexus 2200 platform fabric extenders in single or dual connected mode using enhanced virtual port channel (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 fabric extender 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

●   Low-latency, high-performance computing environments

●   Virtualized access

In addition to these options, the Cisco Nexus 6001 Switch provides unique value as a high-density fabric extender aggregation platform. For example, the Cisco Nexus 6001 Switch can be used in conjunction with the Cisco Nexus 2248PQ, 2232PP, and 2248TP Fabric Extenders as a high-density switching system, consolidating 10 Gigabit Ethernet connections in a single management plane. In addition, a variety of blade fabric extender options can be aggregated into a Cisco Nexus 6001 Switch using 10 Gigabit Ethernet, providing a single point of management for blade server deployments.

Table 1 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.

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.

Multihop FCoE

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.

High-Performance Computing

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.
