Which of the following is the BEST choice for a clustered host interconnect?

1. Infiniband

2. 1Gb Ethernet

3. 10Gb Ethernet

4. Fibre Channel

The correct answer is: Fibre Channel

The best choice for a clustered host interconnect is Fibre Channel due to its design and performance features tailored for high-speed storage area networking (SAN). Fibre Channel technology supports data transfer rates that can exceed those of traditional Ethernet options, particularly in high-demand, high-throughput environments typical of clustered architectures. Fibre Channel typically offers lower latency and higher bandwidth, which is crucial in a clustered environment where multiple servers need to communicate rapidly and efficiently with shared resources, particularly storage. This helps ensure that data can be accessed simultaneously across different nodes with minimal delay, facilitating better resource utilization and improved performance. In contrast, while Infiniband is also a high-speed option, it is not as commonly integrated into typical clustered settings compared to Fibre Channel, which has a broader adoption and a well-established presence in enterprise environments. Ethernet options, such as 1Gb and 10Gb Ethernet, can be sufficient for many workloads but may not provide the same level of performance and reliability required in more intensive cluster applications, making Fibre Channel a more specialized and effective choice for these scenarios.
