摘要： 针对多媒体数据的爆炸式增长急需高性价比的存贮解决方案,提出了一种基于交叉开关的近线存贮系统.该系统利用大容量的SATA硬盘阵列取代机械手控制的磁带库,通过交叉开关矩阵切换实现与主机按需连接.给出了存贮系统的模型,对交叉开关矩阵的硬件和固件设计、主机调度策略的设计思想、系统端口编址、硬盘端口编址、内部开关编址分别进行了阐述.原型系统验证本系统可以很好地满足多媒体业务的需求.

Abstract: The roaring growth of multimedia data demands cost-effective storage solutions in urgent, so that a near-line storage system based on crossbar switch was presented. High-capacity SATA disk array was used in this system instead of tape library, and connects on-demand with the host was implemented through the crossbar switch instead of manipulator. The storage system model was proposed. The hardware and firmware design of crossbar switch matrix, scheduling policy of the host, address-planning of system port, hardware port and internal switch were respectively introduced. The prototype system showed that the proposed system could meet the demand for massive multimedia data storage.
