面向存储资源管理的多协议存储系统

SRM-Based Multi-Protocol Supported Storage

针对网格工作流中存在的跨域数据共享问题,提出了一种基于存储资源管理的多协议支持的存储系统———MPSS.利用管理URL来帮助传输服务区分数据类型;通过将不同的用户映射到不同的私有空间,实现访问空间的隔离;把握控制读写令牌的授权来协调多个传输服务之间的合作关系.这样,透明地实现了跨域的数据共享,极大地简化了网格工作流的执行过程,提高了网格数据共享的效率.MPSS支持常见的传输协议,在实际的航空、药物网格以及气象等项目中表现出了良好的稳定性和效率.压力测试表明,MPSS至少可以处理每秒300次的访问,平均响应时间在1.7 s左右.

An SRM-based multi-protocol supported storage （MPSS） is proposed to solve the data share problem in a grid workflow environment of cross-domain. The MPSS utilizes managed URL to distinguish different data types, insulate users＇ private space through mapping different users＇ space to different physical position, and coordinate different transfer services by controlling authorization of read/write tokens. With these strategies the MPSS implements the data sharing of cross-domain transparently, simplifies the grid workflow＇s running and improves the efficiency of grid data sharing. The MPSS supports popular transfer protocols, provides a powerful supporting for grid workflow of cross-domain, and shows a good stability and efficiency in practical projects such as aviation, DD grid and meteorology. The results of pressure test show that the MPSS can process at least 300 requests per second with an average response time 1.7 s.
