What is the BEST interconnect option for a clustered host environment?

• A. Infiniband
• B. 1Gb Ethernet
• C. 10Gb Ethernet
• D. Fibre Channel

Answer: (D)

In a clustered environment, fast, reliable access to shared storage and dependable inter-node I/O are essential. Fibre Channel provides a dedicated storage area network (SAN) fabric that lets multiple hosts access shared storage with high bandwidth and very low latency, while isolating storage traffic from regular network traffic. This predictable, scalable storage pathway supports multipathing and robust failover, which are crucial for cluster availability and performance, and it is widely supported by enterprise storage arrays and clustered file systems. While other options can be fast—Infiniband excels at node-to-node interconnects in HPC setups, and 10Gb Ethernet offers strong performance for general networks—the primary need in many clustered deployments is a mature, high-throughput, low-latency storage interconnect. 1Gb Ethernet is typically insufficient for modern clustered storage workloads.
