How does Fibre Channel Switch Work?

An Fibre Channel (FC) switch eliminates the need for every server to have a direct connection to every storage array and thus reduces complexity. Although Fibre Channel supports point-to-point connections in which a server physically access the attached storage directly without an FC switch, this architecture doesn’t scale well. An FC switch solves this problem by acting as an intermediary between servers and storage. Servers and storage devices are both attached to an FC switch. When a server needs to access a storage device, the FC switch directs the request to the appropriate storage device.
