A. B. C. D.B.
The correct answer is D. Fiber switch.
A Storage Area Network (SAN) is a high-speed network that connects servers to storage devices, allowing them to share data and access storage resources as if they were directly attached to their local machines. SANs typically use Fibre Channel or iSCSI protocols to transfer data between servers and storage devices.
To connect multiple servers to a SAN, a fiber switch is required. A fiber switch is a specialized network switch that is designed to connect servers and storage devices in a SAN. It provides a high-speed, low-latency network fabric for data transfers between servers and storage devices, and it allows multiple servers to access the same storage resources simultaneously.
Fiber switches typically have multiple ports, which allow multiple servers and storage devices to be connected to the SAN. They also support features such as zoning, which allows administrators to restrict access to specific storage resources based on the server or application that needs to access them.
A router, on the other hand, is used to connect networks together, typically at the Internet level, while a RAID controller is a hardware device used to manage the redundancy of data on hard drives in a server or storage array. While an HBA (Host Bus Adapter) is a hardware device used to connect a server to a SAN, it is not sufficient to connect multiple servers to a SAN.
