NSX vSwitch is the software that operates in server hypervisors to form a software abstraction layer between servers and the physical network.

As the demands on datacenters continue to grow and accelerate, requirements related to speed and access to the data itself continue to grow as well. In most infrastructures, virtual machine access and mobility usually depend on physical networking infrastructure and the physical networking environments they reside in. This can force virtual workloads into less than ideal environments due to potential layer 2 or layer 3 boundaries, such as being tied to specific VLANs.

NSX vSwitch allows you to place these virtual workloads on any available infrastructure in the datacenter regardless of the underlying physical network infrastructure. This not only allows increased flexibility and mobility, but increased availability and resilience.
