- 28. vSphere Networking
Virtual networking (vNetwork) capabilities optimally align physical
and virtual machine networking and provide the networking for hosts
and virtual machines.
vNetwork supports two types of virtual switches:
vNetwork standard switches
•
Virtual switch configuration for a single host
vNetwork distributed switches
•
Virtual switches that provide a consistent network configuration for virtual
machines as they migrate across multiple hosts
