VMware NSX + Cumulus Networks: Software Defined Networking

2,240

Published on

Witness the enablement of a true integration of a virtual network platform and an underlay physical network for a scalable data center orchestration, automation and multi-tenancy solution over high-capacity IP fabrics. With the integration of VMware NSX Layer 2 gateway services on networking hardware running Cumulus Linux, customers can now connect virtual workloads to physical workloads with no performance impact.
