Introduction of VSF
VSF is using the VSF port to connect several servers and build up a virtual logical facility. The u
ser 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 struct
ure design as shown below in the Fig 1-1. 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 decre
ase and at higher cost.
(2) No status internet conk out switch will delay the recover time of application and break out ti
me 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 V
SF 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 through
out 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), likeFig 1-2.
