Setting the Fibre Channel Topology
The term topology indicates how devices are connected to each other. Fibre Channel provides the
following types of topology:
•
Fabric: Utilizes a fabric switch to connect a large number of devices (up to 16 million) together.
Each device will have the full bandwidth of 100 MB/sec.
•
FC-AL (Fibre Channel-Arbitrated Loop): Shared interface that can connect up to 126 devices
(AL-ports) together. The 100 MB/sec bandwidth is shared among the devices connected to
each other.
•
Point-to-point: The simplest fibre topology connects two devices directly together.

When you configure your system, you must use the LUN Manager window to specify whether the
hosts and the storage system are connected via a fabric switch.
