While CPU clock cycle and memory bus speed are reaching the level of sub-nanoseconds and 10Gbytes/sec, disk access time and data transfer rate are still lingering around several milliseconds and 300Mbytes/sec, respectively. Since systems with ever-increasing speed are being deployed at the scale of thousands of nodes, IO speed needs to keep pace with the demand of high performance computing applications. On these systems, high speed interconnects are typically being utilized due to the very low latency and very high bandwidth they can achieve.
