The invention discloses a data storage method and device. The method comprises the steps that first equipment receives an RDMA message sent by second equipment; the RDMA message comprises first information and a load; the first information is used for indicating that the load is stored in a target storage area of the first equipment; and the first device successfully stores the load in the target storage area of the first device according to the first information, and then sends a positive response to the second device. In the RDMAwrite operation, the first equipment feeds back the ACK to the second equipment after determining that the load is successfully written into the target storage area, so that the problem that the second equipment fails to read the data from the first equipment is avoided. 一种数据存储方法及装置，其中方法包括：第一设备接收第二设备发送的RDMA报文；RDMA报文包括第一信息和载荷；第一信息用于指示将载荷存储至第一设备的目标存储区域中；第一设备根据第一信息，将载荷成功存储至第一设备的目标存储区域中之后，向第二设备发送肯定应答。在RDMAwrite操作中，第一设备在确定将载荷成功写入目标存储区域中之后，才会向第二设备反馈ACK，避免出现第二设备从第一设备中读取数据失败的问题。
