HP Virtual Switching Framework (VSF) technology virtualizes two physical devices in the same layer into one Virtual Fabric which provides high availability and scalability. A Virtual Fabric is therefore two physical devices in the same layer that utilize VSF technology.

Virtual Switching Framework (VSF) allows supported switches connected to each other through normal ethernet connections (copper or fiber) to behave like a single switch.
