文中提出了一种改善计算机存储系统写请求特别是小写请求性能的新的存储结构.采用有着高存储速度、高可靠性的固态盘和廉价的硬盘空间共同作为磁光盘的写高速缓存,并结合顺序文件存取技术,从存储体系结构角度出发,研究并实现了一种以较低成本实现快速、可靠、大容量的存储系统.试验表明新型存储系统不必修改现有文件系统,即能大幅提高存储系统性能.系统可用于要求高可靠性的军用环境以及高可靠性和快速大容量要求的民用系统.
In this paper, we propose a new storage structure to improve the performance of computer storage system write requests, especially lowercase requests. Using high-speed, high-reliability solid-state disks and low-cost hard disk space as write-cache for magneto-optical disks, combined with sequential file access technology, from a storage architecture perspective, Costs for fast, reliable, high-capacity storage systems. Experiments show that the new storage system does not have to modify the existing file system, which can significantly improve storage system performance. The system can be used in military environments that require high reliability, as well as in civilian systems for high reliability and fast capacity requirements.
