Fabric Switches Pack Massive Capability into a Small Footprint

Scale out your data center environments with huge capacity and compelling economic benefits. Enable connection with top-of-rack switches or directly to servers. Include automation that lets you add switches network-wide without manual configuration. Then top it off with exceptional application performance.

Resources

Extreme Data Center Fabric Technologies

Address network needs with a choice of architectures
Get simple scalability for L2 and expansive scalability for large L3 deployments
Use resilient, elastic, self-forming, and self-healing fabrics
Centrally manage all VDX switches as a single logical element

Automation and Programmability

Scale out fabrics without complexity with automatic fabric provisioning and network virtualization
Enable cloud-like agility and rapid innovation through open interfaces: Puppet, Ansible, VMware vRealize plugins, REST and Netconf APIs
Improve programmability with faster, more elegant integration with in-house and third-party management and orchestration tools
Easily orchestrate fabric services through the OpenStack and OpenDaylight-based SDN Controller
Provide a choice of multitenant solutions using Virtual Fabrics for tenant isolation within a data center and across data centers
Reduce maintenance costs and gain high availability through automated service and resource upgrades

Two high-density models support spine and leaf applications

The 6940-36Q is a 40 GbE, 1U switch primarily designed for spine applications, but very capable in a leaf deployment
The 6940-144S is a 2U switch that provides 96 fixed 10 Gb ports for demanding leaf applications
Support more than 10,000 servers using VCS multi-fabrics with overlays and 500,000 servers with IP Fabrics

Optimized for performance and scale

24 MB buffers deliver line-rate performance for all packet sizes on all ports
800 ns port-to-port latency supports speedy data transmission with a minimum of dropped packets
Wire-speed switching across all ports and all packet sizes
Auto-trunking Inter-Switch Links (ISLs) in VCS Fabrics
Non-disruptive scaling

DHCP Automatic Fabric Provisioning

Configure a new switch simply by plugging it in. Thanks to Extreme VCS fabric technologies, power and a network connection are all you need. The switch immediately becomes part of the network fabric, automatically provisioned and centrally managed

Better Performance for Large Infrastructures

Infrastructures with extensive traffic require lots of switch ports. And the VDX 6940 is an undisputed industry leader, with the market’s highest 10 GbE and 40 GbE port density in a fixed form factor switch. And with line rate throughput across all ports, you gain better application performance during bursty traffic

Balanced Design Improves User Experience

Moving traffic quickly across the network and ensuring ideal application performance requires unique switch characteristics. The VDX 6940 boasts a uniquely optimized packet buffer and latency that addresses both challenges. Outstanding throughput and performance, end to end.

Small Footprint Means More for Less

The VDX 6940 capabilities easily measure up to or surpass chassis offerings from competing vendors. But its size doesn’t. The small, rack-mounted design means a lower purchase cost and ongoing operational efficiencies such as reduced power, cooling and space requirements.

Programability: A Gift To Productivity

The days of manually configuring individual switches are over. The VCS Fabric, IP Fabric, APIs, and scripting tools let you automate switch feature implementation across the network. And those scripts live on, through operating system upgrades, personnel changes, and more. Greater operational efficiency, ongoing ROI
