What does HBA stand for in SAN networking?

• A. Host Bus Adapter
• B. Host Bridge Adapter
• C. Hypervisor Bus Adapter
• D. Hardware Bus Access

Answer: (A)

In SAN networking, the term HBA refers to the hardware interface that connects a server (the host) to the storage network. An HBA is a card installed in the server that provides the physical and logical connection to the storage fabric, whether Fibre Channel, iSCSI, or another SAN protocol. It handles the protocol processing and data transfer between the host’s operating system and the storage network, enabling I/O operations to reach storage devices efficiently. The other terms don’t match standard SAN terminology, so the correct expansion is Host Bus Adapter.
