Automating OpenStack Clouds with Unified Physical + Virtual SDN Fabrics

Big Cloud Fabric™ supports seamless integration with OpenStack through the Neutron plugin for L2/L3 networking and L4-7 service insertion. With the Big Cloud Fabric Controller and Horizon dashboard enhancements from Big Switch Networks®, managing both physical and virtual switching infrastructure in the data center from a single pane of glass is now a reality!

Take the Big Switch Networks SDN Challenge!

OpenStack infrastructure teams and end users benefit from simplified network deployment for existing or new pods, streamlined application deployment workflows, enhanced analytics and simplified troubleshooting across physical and virtual environments. With Big Cloud Fabric, OpenStack networks are 8x faster to setup initially, 12x faster to configure, deploy applications and troubleshoot, and 20x faster when upgrading.
