Big Switch Adds VMware Support

ONUG, New York City, NY — Big Switch Networks, which provides hyperscale-inspired network architecture to data centers worldwide, now brings physical network automation and visibility to VMware virtualization environments. Big Cloud Fabric (BCF) – an open SDN fabric designed to transform complex, expensive, and proprietary box-by-box networking – offers enterprises dramatic improvements in network agility, automation, and white-box switch economics. The Big Cloud Fabric 2.6 release, announced at this week’s Open Networking User Group (ONUG) conference, delivers physical network automation and physical network visibility to VMware NSX, with seamless integration with vCenter to support any VMware vSphere workload.

With Big Cloud Fabric – an SDN-based physical fabric – virtualization administrators are now able to engage with a highly responsive physical network that operates at the same pace as VM creation/deletion and VM live migration (e.g., vMotion) events. For rapid troubleshooting across virtualization and physical fabric environments, BCF 2.6 also provides flow tracing across the fabric topology (source leaf switch, associated spine switch, and destination leaf switch).

The 2.6 release introduces an enhanced Fabric Analytics module that supports deep visibility of VMware VMs for network administrators, including VM and host properties, VM mobility events, and host connectivity to the BCF leaf switches. Having a consistent view of virtualization environments across both virtualization and network admins allows for the rapid resolution of cross-domain issues.  

NSX-v Support and Visibility in BCF 2.6
VMware NSX-v (for vSphere environments) constructs a vSwitch-based SDN overlay and requires an IP-based physical network to provide network virtualization and micro-segmentation. While traditional box-by-box networking is an option for the physical underlay, the manual CLI-driven management and challenging workflows for underlay visibility/troubleshooting are complex and manual operations. As the simplest and most cost-effective SDN underlay, Big Cloud Fabric provides a highly optimal architecture for NSX-v SDN overlay.

Specifically, Big Cloud Fabric 2.6 extends support for VMware NSX-v network virtualization overlay by providing:

  • Complete NSX VM and host (Virtual Tunnel End Point or VTEP) visibility in the BCF controller
  • BCF Fabric Analytics extended for NSX-v VMs
  • Rapid VTEP-to-VTEP trouble-shooting on BCF fabric underlay across the fabric, including source VTEP, source Leaf, spine, destination leaf, and destination VTEP

Customers can benefit from operational simplicity and commodity economics of the Big Cloud Fabric SDN underlay while closing the visibility gap with NSX-v overlay and traditional physical switch deployments.

Big Cloud Fabric 2.6 – shipping and available today – includes advance vSphere integration, Fabric Analytics for vSphere, and support for NSX-v.


  • Big Cloud Fabric 2.6 software is licensed on a per-switch subscription basis
  • Existing BCF customers can upgrade to BCF 2.6 without any additional cost
  • Big Switch offers $39K and $99K BCF starter kits, inclusive of HW switches, SW, support and cables/optics, for interconnecting up to 80 compute nodes.
