中文摘要：

根据流水线技术，将光纤通道适配器的数据传输阶段与SCSI适配器的I／O任务执行阶段按流水线技术并行执行，能充分减少系统总的处理时间，提高系统总的数据传输速度．以FC—RAID3000为例，分析了磁盘阵列中I／O流水线技术的适用性与基本原理，介绍了通过设置多进程来并行处理光纤卡和SCSI适配器的数据传输过程，对实现流水线前后的性能进行了测试和比较．经测试发现，阵列系统最大数据传输率与未采用流水线技术的系统相比提高了1倍．

英文摘要：

According to pipeline technology, the data transmission of I/O task was divided into FC adaptor＇s transferring data and SCSI adaptorrs executing I/O tasks, and multiple I/O commands can be executed parallelly to improve the transmission rate of the system. Taken FC-RAID 3000 as an example, the basic principle of I/O pipeline technology in RAID and its uses were analyzed. The data transmission process of fiber cards and SCSI adapter were described, in which the data were parallelly handled by multi-process technology. The performance of the system was .experimentally tested. The results show that the transmission rate of data in the system are doubled than that of the system in which I/ O pipeline technology is not used.
