Infiniband通道磁盘阵列中目标器的设计与实现

磁盘阵列对海量信息的存储与处理,数据的可用性和性能具有重要的意义,目标器为主机提供设备映射和设备访问接口.设计和实现了SRP协议的目标器,通过主机HCA卡GUID标识来实现存储系统逻辑资源的授权访问,对目标器对读写请求的处理流程进行了介绍,采用评测工具对SRP协议目标器模块进行了性能测试,测试结果表明SRP协议目标器具有较好的性能,最高数据传输率达到IB理论带宽的极限.

Design and Implement of Infiniband Target in Disk Array

Disk Array is of great significance to storage and processing in massive information, data availability and performance. the target provide device mapping and device access interface for the host. the SRP target is designed and implemented in this paper, and it implement the authorization visit through the GUID identifier which controls the host access resources in storage system. The read and write requests processing in SRP target is introduced in the paper. Finally we use some general benchmarks to evaluate the performance of SRP target module, the test results showed that the SRP target has better performance, reach to the maximum theoretical data transfer rate.
