Storage controllers are connected only to disk enclosures within Fibre Channel networks.

• A. True
• B. Not applicable
• C. False
• D. Sometimes

Answer: (C)

In Fibre Channel storage environments, the storage controller sits between hosts and the disk drives. It has front-end connections to talk to host HBAs through the FC fabric, and back-end connections to access the disks in the enclosures. This setup lets the controller present storage (LUNs) to hosts and manage I/O across multiple paths, providing redundancy and performance. Because of this dual role—connecting to both hosts and disk back-ends—the statement that storage controllers are connected only to disk enclosures is not correct. They are not limited to talking to disks; they also connect to hosts via the FC fabric to serve data.
