Which protocol is specifically a Fibre Channel protocol used in SAN networking?

Fibre Channel is the protocol built for SAN environments, providing a dedicated, high-performance transport that supports low latency and high throughput for block storage. In a SAN, storage is accessed as raw blocks rather than files, so the transport must handle rapid I/O with reliable, lossless delivery—exactly what Fibre Channel delivers through its fabric-based architecture and specialized flow control. The other options operate in different contexts: iSCSI carries SCSI commands over IP networks to enable block storage over Ethernet but is not the Fibre Channel protocol itself; CIFS and NFS are file-sharing protocols for accessing files over a network, not the block-level transport used in SANs. Therefore, the protocol specifically used in Fibre Channel SAN networking is Fibre Channel.
