Duplication Between A Server And A Hub And Between Switches On The Same Network (Nic Switch Method) - Fujitsu PRIMEQUEST 480 System Design Manual

CHAPTER 6 Redundant Configuration
6.5.2 Duplication between a server and a hub and between
switches on the same network (NIC switch method)
In the NIC switch method, as shown in
Card (NICs) are connected on the same network, and switch of transmission lines is
controlled by exclusive use. With this method, communication destinations are not
restricted. It is possible to communicate with hosts on the same network and on
different networks. Since the range of duplication is restricted to the directly
connected switches and hubs, to duplicate the entire communication path, it is
necessary to duplicate routers and other network devices located halfway as well as
the transmission line of the communication destination.
