79.1 Overview
79.1.1 Introduction of VSF
VSF is using the VSF port to connect several servers and build up a virtual logical facility. The user cans this
virtual machine to manage all the physical facilities that link up together.
Traditional district and the data center network is using the multiple layer network topology structure design as
shown below in the Figure 83-1. The following are the drawbacks of this type of network:
(1) The network and the server are complicated, thus it will cause the operation efficiency decrease and
at higher cost.
(2) No status internet conk out switch will delay the recover time of application and break out time of
operation.
(3) Low usage of resources will decrease the return of income (ROI) and increase the capital.

In order to solving these problems, VSF comes. Make up more than one device whichsupports VSF to be the
single virtualization switch. In VSF, the data panel of the management engine and the exchange array of
both switches can be activated at the same time. Members of VSF can throughout the VSL to connection.
The VSL standard among the members of the switches is using million-mega Ethernet for connection
(maximum have 4 linkages, to provide redundance), like Figure 83-2.
