基于IBA的SRP Target的研究与实现

Research and Realization of SRP Target Based on IBA

SRP Target的功能主要是接收SRP Initiator发送的SRP请求,调用内核函数完成请求任务和在SRP Initiator和SCSI存储设备之间以RDMA方式进行数据传输。本文研究了SRP target的实现,搭建了IBA存储网络的实验环境,并进行了性能测试。

InfiniBand is a new interconnect technology of that separates the I/O system from the CPU/Mem. SRP is a communication protocol of InfiniBand. This paper researches on SRP. It analyses SRP Target processed SCSI commands including in the SRP information unit. It describes the process that SCSI commands are transferred between SCSI devices via RDMA, and the RDMA data transfer. An experiment environment of storage network based in IBA is built, and it makes a performance evaluation of SRP storage devices.
