摘要

PPROBLEM TO BE SOLVED: To solve the problem that a conventional self-evident communication path redundancy system has while maintaining quick switch operation of communication paths when a failure occurs on the communication path. PSOLUTION: During normal operation, only one of redundant communication paths is used to transfer data between hosts A and B. In the host A, data are read from a disk, stored in a segment (RDMA region) on a main memory, and the data are transferred to the host B by using an LMR group 1 via a communication path 1 by RDMA. In the host B, the LMR group 1 is used and the data received from the communication path 1 are stored in the main memory. When the failure occurs in the communication path 1, the hosts A and B switch the LMR group to be used for RDMA from the LMR group 1 to LMR group 2 and restarts data transfer by the RDMA from the segment on the main memory which is not transferred to the host B yet.

要解决的问题：解决传统的不言自明的通信路径冗余系统具有的问题，同时当通信路径发生故障时，保持通信路径的快速切换操作。

解决方案：在正常运行期间，仅使用一条冗余通信路径在主机A和主机B之间传输数据。在主机A中，数据是从磁盘读取的，存储在主存储器的段（RDMA区域）中，并且通过RDMA通过通信路径1使用LMR组1将数据传输到主机B。在主机B中，使用了LMR组1，并且将从通信路径1接收的数据存储在主存储器中。当通信路径1中发生故障时，主机A和主机B将要用于RDMA的LMR组从LMR组1切换到LMR组2，并重新启动RDMA从主存储器上没有该段的数据传输转移到主机B了。
