[0004] The other is the pure software method or the mirror method, that is, the application data required by the two servers are stored in their own servers without using a common storage device. Although the hardware investment is small and the cost performance is high, the data can only be synchronized through the network. Not suitable for systems with high data throughput

Abstract

The invention relates to an FPGA hot standby controller for master-slave hot standby, and belongs to the technical field of computer\servers. The hot standby controller comprises a health state comparison module, a switching control module, a storage control module and a remote control module, wherein the health state comparison module receives and compares the health state information of the master device and the slave device, and sends a comparison result to the switching control module and the remote control module; the switching control module is responsible for switching control of the master device and is controlled by the health state comparison module and the remote control module; the storage control module realizes a connection path between the master / slave device and the disk array through a PCIe root port; the remote control module remotely receives health state information of the master device and the slave device, and switching between the master device and the slave device can be carried out through the remote control module. According to the hot standby controller, the requirement for server hardware configuration is not high; and by utilizing the characteristics of parallel processing and high real-time performance of the FPGA, the time required for dual-computer switching can be shortened, and the influence of service interruption is reduced.

Description

technical field [0001] The invention relates to an FPGA hot backup controller for master-slave dual-machine hot backup, and belongs to the technical field of computers / servers. Background technique [0002] Dual-machine hot backup is aimed at long-term service interruption caused by server failure, ensuring long-term and reliable service of the system. [0003] Currently, there are two implementation methods for dual-system hot backup. One is the sharing method, that is, two servers are connected to the same shared storage device. Once the master server fails, the slave server will switch in a short period of time to take over all the resources on the master server and become the new master server. Due to the use of shared storage devices, the two servers actually use the same data, which protects the uninterrupted operation of business applications. Because there is an independent storage device, high data throughput can be achieved, but it also increases the cost. [00...
