Sections 4.4 and 4.6 provided an overview of Fibre Channel topologies and the Fibre Channel protocol. Continuing with the top-down approach, it is time to consider the various different devices and elements that are used to construct a Fibre Channel SAN. These elements, referred to as the building blocks of a Fibre Channel SAN, are
Host bus adapters
Fibre Channel cables
Interconnect devices, which include hubs, switches, and fabric switches
All of these are described in Sections 4.7.1 through 4.7.4. Note that all addressable entities on a Fibre Channel SAN have unique World Wide Names. These are analogous to the unique MAC addresses for Ethernet interfaces. In Fibre Channel, the World Wide Name is a unique 64-bit ...
