Fibre Channel (FC) is the best suited technology for the described scenario since it provides a high-speed network technology primarily used for storage networking. It offers low-latency, lossless data transmission, and is specifically designed for transporting block storage data, making it ideal for environments with frequent and large-scale data transfers that require block-level storage access. Ethernet, while versatile and widely-used, generally does not provide the same level of performance for block storage traffic and low-latency requirements as FC does. While InfiniBand provides high bandwidth and low latency, it is more commonly used in high-performance computing (HPC) environments rather than for block storage. Multiprotocol Label Switching (MPLS) is primarily used for creating virtualized, high-performance telecommunication networks and is not specialized for storage networking.
