Description

一种数据传输方法、相关装置及数据传输系统A data transmission method, related device and data transmission system

技术领域technical field

本发明涉及通信领域,尤其涉及一种数据传输方法、相关装置及数据传输系统。The present invention relates to the communication field, in particular to a data transmission method, a related device and a data transmission system.

背景技术Background technique

为了提高数据传输的可靠性,避免单点故障,应用服务器与存储系统之间往往采用多条链路(称为路径)相连的方式来进行数据传输。多路径软件负责管理多条路径,并选取优选路径下发输入/输出(Input/Output,I/O)以保证业务性能,并负责路径故障时I/O能切换到备用路径下发:In order to improve the reliability of data transmission and avoid a single point of failure, multiple links (called paths) are often used between application servers and storage systems for data transmission. The multi-path software is responsible for managing multiple paths, and selects the optimal path to send input/output (Input/Output, I/O) to ensure business performance, and is responsible for switching I/O to the backup path when the path fails:

当前的选路算法中,如图1,有些是在选择路径时仅考虑选择优选控制器中的路径,发送所有I/O到该单条路径(即图1中的路径2),在该算法中,若某条路径发生故障,那么选择备用路径来发送所有的I/O;如图2,还有些是将I/O平均分布于所有可用的优选控制器路径上(即图2中的路径1和路径2平分进行数据传输)。In the current routing algorithm, as shown in Figure 1, some of them only consider the path in the preferred controller when selecting a path, and send all I/O to this single path (that is, path 2 in Figure 1), in this algorithm , if a path fails, then choose a backup path to send all the I/O; as shown in Figure 2, some evenly distribute I/O to all available preferred controller paths (that is, path 1 in Figure 2 and path 2 for data transmission).

然而,上述选路方法未充分考虑实际使用环境中各路径的主机总线适配器(Host Bus Adapter,HBA)卡硬件差异,存在所选择路径未在高性能HBA卡最优的路径上下发的可能,或者未能合理利用高性能HBA卡的性能优势,导致I/O的处理效率不高,硬件利用率较低。However, the above path selection method does not fully consider the differences in the host bus adapter (HBA) card hardware of each path in the actual use environment, and there is a possibility that the selected path is not delivered on the optimal path of the high-performance HBA card, or The performance advantage of the high-performance HBA card cannot be properly utilized, resulting in low I/O processing efficiency and low hardware utilization.
