What native Fibre Channel technology facilitates connecting multiple Fibre Channel devices behind a single FC address?

Fibre Channel Arbitrary Loop

Explanation:

Fibre Channel Arbitrary Loop (FC_AL) which also called arbitrated loop refers to Fibre Channel topology in that allows for a one-way loop connection of many devices in a ring topology.

Historically, Fibre Channel Arbitrary Loop originally invented to serve as an alternative to the fabric topology that was being connected through the very expensive Fibre Channel switches. Fibre Channel Arbitrary Loop then assisted in collecting a large number of servers and computer storage devices while the highly expensive Fibre Channel switches were totally not used. This led to an appreciable fall in the cost of the Fibre Channel switches making to become obsolete and it no longer used in server-to-storage communication.

Therefore, the native Fibre Channel technology facilitates connecting multiple Fibre Channel devices behind a single FC address is Fibre Channel Arbitrary Loop.
