Which storage protocol allows administrators to reduce the total number of network ports used in the network environment?

Fibre Channel over Ethernet (FCoE) consolidates Fibre Channel traffic onto Ethernet but still requires dedicated FCoE-capable network components and often doesn't reduce the *total number* of physical ports as much as vSAN's full convergence.

vSAN is a software-defined storage solution that pools direct-attached storage from ESXi hosts and leverages standard Ethernet networking for storage traffic, eliminating the need for dedicated storage arrays, Fibre Channel HBAs, and their associated network ports.

Fibre Channel (FC) is a dedicated storage protocol that requires separate HBAs, switches, and cabling, which inherently increases the number of network ports in the environment.

Network File System (NFS) uses standard Ethernet ports but still relies on external NAS devices, each with its own network interfaces, and does not provide the same level of port reduction through compute-storage convergence as vSAN.
