SG0-001 · Question #64
Which of the following is a SAN initiator?
The correct answer is B. Host Bus Adapter. A Host Bus Adapter (HBA) is the component in a server that acts as an initiator, connecting the server to a Storage Area Network (SAN) to send I/O requests.

Why each option
A Host Bus Adapter (HBA) is the component in a server that acts as an initiator, connecting the server to a Storage Area Network (SAN) to send I/O requests.
A target mode Fibre Channel adapter is used by the storage device itself to receive and process I/O requests, functioning as the target, not the initiator.
A Host Bus Adapter (HBA) is a hardware component installed in a server that provides connectivity to a Storage Area Network (SAN). It acts as the initiator, enabling the server to send I/O requests to storage targets on the SAN.
CIFS is a file-level protocol typically used over Ethernet for Network Attached Storage (NAS), and an Ethernet interface is not a SAN initiator for block-level storage.
A SAN switch SFP (Small Form-Factor Pluggable) is a transceiver module for physical connectivity within the switch, not a device that initiates I/O requests.
