1.1 Topologies in Fibre Channel Interface
Three kind of topologies are defined in ANSI standards. (Arbitrated Loop, Fabric
and Point-to-Point)
and Point-to-Point)
The drive supports Arbitrated Loop and Fabric as the primary topologies for the
drive connections.

Figure 1.1 shows the example of connection for disk drives in FC-AL.

BC are port bypass circuits on the back plane commonly, where Node mean the
Target or initiator.

Each Loop signal is transmitted by one-way direction and made of electrical wires
called “link”.
called “link”.
Each node is connected to the loop vial the port which the node owns. Each port
consists of the receiver which receives information from the loop and the
transmitter which sends information.
consists of the receiver which receives information from the loop and the
transmitter which sends information.
In this example, each node has two ports building two independent loops.
Information is propagated between the nodes on the loop through serial signals.
Information is propagated between the nodes on the loop through serial signals.
This section describes the Node, Port, BC and link forming the above diagram
and the signals propagated on the link.
