VDX 6940 Switches Overview

The VDX 6940-36Q is a fixed 40 Gigabit Ethernet (GbE)- optimized switch in a 1U form factor. It offers 36 40 GbE QSFP+ ports and can be deployed as a spine or leaf switch. Each 40 GbE port can be broken out into four independent 10 GbE SFP+ ports, providing a total of 144 10 GbE SFP+ ports. Deployed as a spine, it provides options to connect either 40 GbE or 10 GbE uplinks from leaf switches. By deploying this high-density, compact switch, data center administrators can reduce their TCO through savings on power, space, and cooling.

In a leaf deployment, 10 GbE and 40 GbE ports can be mixed, offering flexible design options to cost-effectively support demanding data center and service provider environments. As in other VDX platforms, the VDX 6940- 36Q offers a Ports on Demand (PoD) licensing model. VDX 6940-36Q is available with 24 ports or 36 ports. The 24-port model offers a lower entry point for organizations that want to start small and grow their networks over time. By installing a software license, organizations can upgrade their 24-port switch to the maximum 36-port switch.

The VDX 6940-144S is a 10 GbE-optimized switch with 40 GbE or 100 GbE uplinks in a 2U form factor. It offers 96 native 1/10 GbE SFP/SFP+ ports and 12 40 GbE QSFP+ ports, or 4 100 GbE QSFP28 ports. In addition, the VDX 6940-144S provides flexibility for uplinks, 40 GbE or 100 GbE from leaf switches, and delivers greater cross-sectional bandwidth for east-west traffic. Purpose-built for scale-out data centers and service providers, it enables aggregation of multiple server racks with a single

With its high density, the VDX 6940-144S is an ideal fit for middle-of-row or end-of-row data center deployments. By connecting multiple racks to a single cut-through switch, this architecture offers greater crosssectional bandwidth for applications. Servers from multiple racks can be just one hop away from one another. The compact 2U form factor saves space, also reducing power and cooling, resulting in lower TCO.

VDX 6940 switches provide the advanced feature set that data centers require while delivering the high performance and low latency virtualized environments demand. Together with Extreme data center fabrics, these switches transform data center networks by enabling cloud-based architectures that deliver new levels of scale, agility, and operational efficiency. These highly automated, software-driven, and programmable data center fabric design solutions support a breadth of network virtualization options and scale for data center environments ranging from tens to thousands of servers. Moreover, they make it easy for organizations to architect, automate, and integrate current and future data center technologies while they transition to a cloud model that addresses their needs, on their own timetable and on their terms.


Optimizes Scale-Out Architecture

VDX switches are designed to help organizations stay ahead of application-driven network change by enabling agile growth through a scale-out architecture. This approach offers three key benefits. First, it enables network expansion as a business grows over time. Data center administrators can horizontally scale spine switches as the number of leaf switches increases. Second, scale-out architecture enables the creation of resilient network fabrics, eliminating a single point of failure and potential downtime. Third, and most important, scale-out network architecture delivers a compelling economic benefit. Unlike scale-up, a scale-out model reduces upfront investment. And by using high-density fixed switches, it lowers the Total Cost of Ownership (TCO), reducing power, cooling, and data center space.

Transforms Networks to Deliver New Levels of Scale, Agility, and Operational Efficienc

VDX switches enable organizations to evolve their data center networks at their own pace, with full investment protection. As the foundation for several data center architectures, VDX switches support Extreme Networks IP fabrics, Extreme VCS fabrics, as well as network virtualization, including controller-based network virtualization architectures, such as VMware NSX, and standards-based (BGP-EVPN) controller-less architectures with Extreme BGP-EVPN Network Virtualization for architectural flexibility (see Figure 1).

For organizations seeking automated provisioning capabilities to improve IT agility, VDX switches, together with Extreme VCS Fabric technology, accelerate time to value through automated provisioning of network devices and network virtualization. Automated service and resource upgrades further reduce ongoing maintenance time and costs. High availability is achieved through non-disruptive In-Service Software Upgrade (ISSU) and self-healing fabrics.

Figure 1: Multiple network architectures offer the flexibility that can help organizations rapidly adapt to changing business conditions and traffic patterns.

Optionally, for DevOps-centric organizations, Extreme VDX switches can be provisioned using Extreme Workflow Composer™ and Extreme Workflow Composer Automation Suites.

Turnkey and Customizable Lifecycle Automation

Meets Today’s Application Demands with High Performance and Low Latency

As data centers virtualize more of their servers and VM density per server increases, organizations will require higher bandwidth connectivity to support the explosion of data and application processing. With 1/10 GbE and 40 GbE options, VDX 6940 switches deliver the highperformance computing needed to keep up with the demands of a virtualized data center, allowing organizations to reduce network congestion, improve application performance, and meet the capacity required by 10 GbE servers. The 40 GbE and 100 GbE uplinks can easily aggregate high-bandwidth traffic and reduce bottlenecks that occur when aggregating multiple 10 GbE or 40 GbE connections, keeping data center networks working at peak performance.

In an Extreme VCS fabric, VDX 6940 switches also help maximize network utilization with hardware-based Extreme Inter-Switch Link (ISL) Trunking. Organizations can create a 120 GbE Extreme ISL trunk by utilizing three 40 GbE ports or 12 10 GbE ports between VDX 6940 switches. The Extreme ISL trunk is automatically formed between two Extreme VDX switches when they are linked together, allowing traffic to be equally distributed among all ports. This increases link efficiency and limits traffic disruptions, especially during high-traffic times. Also, 40 GbE and 10 GbE trunking is supported between VDX 6940, 6740, and 8770 switches.

Extreme Metro VCS technology provides an innovative solution to interconnect data centers and their traffic flows over distance, guaranteeing supported traffic characteristics. Metro VCS technology configured for regular Ethernet traffic supports 10 GbE ISLs up to 80 km, 40 GbE ISLs up to 40 km, and 100 GbE ISLs up to 40 km.

VDX 6940 switches offer a unique balance between two conflicting attributes—buffer and latency. Niche products with very high buffer often suffer from high latency, and products with ultra-low latency are not a good fit for data centers with bursty traffic. VDX 6940 switches, with a purpose-built data center chip, excel in optimizing buffer and latency to deliver better application performance. These switches deliver 800 ns any-port-to-any-port latency. In addition, they offer an industry-leading 24 MB deep buffer. This provides the buffering capacity to handle increases in traffic, especially during peak times when ports are congested, allowing traffic to be distributed across the ports. VDX 6940 switches also feature a single ASIC design, instead of multiple ASIC designs commonly found in other switches. This improves performance since all ports communicate via the one ASIC.

Cloud and Big Data Environments

VDX 6940 switches deliver optimized buffer and latency and high performance to enable greater cross-sectional bandwidth for east-west traffic—exactly what cloud workloads demand. These switches offer the flexibility needed to scale out networks, deliver intelligence to more effectively manage VM mobility, as well as provide an SDN-enabled and programmable infrastructure. In addition, VDX 6940 switches offer an advanced feature set that non-virtual and Big Data environments require. With 10, 40, and 100 GbE options for designing oversubscribed or nonoversubscribed networks, high throughput, and optimized buffer and latency, the VDX 6940 is an ideal switch for Big Data applications. Together with Extreme data center fabrics, VDX 6940 switches can simplify network design and operations for both cloud and Big Data network fabrics.

Figure 2: The Workflow Composer architecture brings workflow-centric, cross-domain network automation to IT operations.

Fits into Any Data Center Design

VDX 6940-36Q and 6940-144S front access ports are positioned to enable easy server or switch connectivity and to simplify cabling. With a choice of front-to-back or back- to-front airflow, these switches are ideal for deployments connecting servers, storage, and other switches, as well as for providing compatibility for either hot aisle or cold aisle data center designs. For the 40 GbE ports that also support 10 GbE connections with breakout cables, the switches offer the flexibility needed to support a mixed environment as data centers or service providers transition to higher bandwidth.

VDX 6940 switches are designed to connect data centers in multiple ways to meet individual design requirements. This flexible design provides investment protection, giving organizations a single switch that can support varying data center requirements. The following features help organizations meet their evolving needs:

  • 10/40/100 GbE uplinks: The 40 GbE QSFP+ ports offer the flexibility to expand and interconnect the network infrastructure intelligently and efficiently while reducing bottlenecks. VDX 6940 switches offer the option to separate each 40 GbE uplink into four 10 GbE uplinks via breakout cables. As capacity and need increase, organizations can revert to 40 GbE when ready.
  • Ports on Demand: Ports on Demand (PoD) enables organizations to activate additional ports. They can purchase the number of ports that they currently need and seamlessly scale up later by simply applying a software license. This flexible and cost-efficient “pay as you grow” licensing model solves scalability challenges by allocating IT resources as needed.

Maximizes Network Availability with Efficiency and Resiliency
Extreme data center fabrics create a more efficient and resilient network, and deliver the high performance and high reliability required by modern data centers, including cloud and highly virtualized environments.

Optimizing East-West Traffic
Traditional data centers are architected with a rigid, threetier tree topology optimized for the north-south traffic flow of client-server computing environments, compromising performance, increasing latency, and creating bottlenecks. With the increased prevalence of virtualization and distributed applications, data center network traffic is now predominantly east-west, or server-server. Extreme data center fabrics were designed and optimized to address these traffic patterns by moving traffic through any of the active paths and avoiding the multiple hops required in other tiered topologies.

In-Service Software
Upgrade The VDX 6940 delivers a highly efficient In-Service Software Upgrade (ISSU) by leveraging a software model that uses a dual-OS infrastructure on a multi-core CPU. This enables data center administrators to deliver enterpriseclass business continuity on fixed switches during a software upgrade/downgrade process. This software change process is non-disruptive to Layer 2, Layer 3, Fibre Channel, and Fibre Channel over Ethernet (FCoE) traffic. Moreover, the ISSU implementation is hardware-optimized, thus reducing the time it takes to complete the upgrade/ downgrade process.

Advanced Storage Support
VDX 6940 switches provide advanced storage support with multiple storage connectivity options, including FCoE, iSCSI, and NAS. They also feature Data Center Bridging (DCB), which enables the reliable exchange of storage traffic over the LAN, eliminating packet loss when network congestion occurs and allocating bandwidth as needed to keep the network running efficiently. Moreover, VDX 6940 switches offer NAS Auto QoS intelligence to prioritize delay-sensitive IP storage traffic within the fabric and to help ensure consistent performance while decreasing latency
