英文摘要：

RATD has been the key component for constructing enterprise storage system. The target module supports host for the access interface of storage devices. This paper discusses the function of the target module based on a prototype of Fiber Channel RAID system. Further analyses the internal architecture of target module and gives an elaboration on the various workflows of the read/write access. Finally, we use some general benchmarks to evaluate the performance of this Fiber Channel target module and RAID system. Testing results reveals a moderately sucessful performance of the Fiber Channel target module.
