本文介绍了一个磁盘子系统改进的情况。从实际运行的结果可以得出结论:只要软、硬件配合得当,就能有效地改善子系统性能,充分发挥设备效益。磁盘子系统是主机系统的一个重要组成部份,其性能的优劣自然也影响着整个系统。因而,本文亦试图从系统设计的观点,提出一点看法,以提高子系统的性能。 This article describes an improved disk subsystem. From the actual operation of the results can be concluded: as long as the soft hardware properly, you can effectively improve subsystem performance, give full play to equipment efficiency. Disk subsystem is an important part of the host system, the pros and cons of its performance will naturally affect the entire system. Therefore, this article also tries to make a point of view from the system design point of view, in order to improve the performance of the subsystem.
