Which of the following allows you to connect a server to storage devices with speeds of 128 Gbps?

Fibre Channel is a high-speed network technology primarily used to connect computer data storage to servers. It supports various speeds, including 128 Gbps, making it well-suited for environments that require high bandwidth and low latency, such as data centers and storage area networks (SANs). Fibre Channel also facilitates efficient transfer of large volumes of data without significant overhead, making it an optimal choice for connecting servers to storage devices in scenarios where performance is critical.

Other options, while they offer functionality for connecting servers to storage devices, typically do not reach the specified speed of 128 Gbps. Ethernet, while widely used, generally has speed limitations that would not meet this requirement under standard configurations. iSCSI, which operates over Ethernet, is constrained by the speeds of the underlying Ethernet network and is better suited for lower performance needs. SAS (Serial Attached SCSI) provides direct connections to storage devices and can achieve high speeds, but it typically maxes out at 12 Gbps per link, making it insufficient for the specified 128 Gbps requirement. Therefore, Fibre Channel stands out as the only viable option that meets the speed criteria presented in the question.
