What component is used to connect a host to a SAN using a fiber connection?

• A. VNIC
• B. NIC
• C. HBA
• D. SCSI adapter

Answer: (C)

To connect a host to a SAN over a Fibre Channel fiber link, you need a device that provides the server’s interface to the Fibre Channel fabric. That is the Host Bus Adapter. The HBA sits in the host and presents a Fibre Channel interface, translating I/O into FC frames that travel through FC switches to storage. A NIC handles Ethernet networks (including iSCSI over Ethernet but not Fibre Channel), so it isn’t the standard path for Fibre Channel SANs. A SCSI adapter is for traditional SCSI or specific legacy setups, not the typical Fibre Channel SAN connection. A VNIC is a virtual network interface inside the host and doesn’t provide the actual Fibre Channel connectivity to a SAN. So the Host Bus Adapter is the correct component.
