Technical Field
The invention relates to an FPGA hot standby controller for master-slave dual-computer hot standby, belonging to the technical field of computers/servers.
Background
The dual-computer hot standby aims at long-time service interruption caused by the fault of the server and ensures long-term and reliable service of the system.
Currently, there are two implementation modes for dual-computer hot standby. One is a sharing method, that is, two servers are connected to the same shared storage device, and once the master server fails, the slave server switches in a short time to take over all resources on the master server to become a new master server. Because shared storage equipment is used, the two servers use the same data in reality, and the service application is protected from running continuously. Because of the separate storage devices, higher data throughput can be achieved, but at the same time costs are increased.
The other is a pure software mode or a mirror image mode, namely application data required by two servers are placed in respective servers, a common storage device is not used, although the hardware investment is low and the cost performance is high, the data can only be synchronized through a network, and the system is not suitable for a system with high data throughput.

The technical problem to be solved by the invention is as follows: an FPGA hot standby controller for master-slave dual-computer hot standby is provided.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: an FPGA hot standby controller for master-slave hot standby comprises a health state comparison module, a switching control module, a storage control module and a remote control module;
the health state comparison module receives and compares the health state information of the master equipment and the slave equipment, and sends the comparison result to the switching control module and the remote control module;
the switching control module is responsible for switching control of the main control equipment 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 equipment and the disk array through a PCIe root port;
the remote control module is used for remotely receiving the health state information of the master equipment and the slave equipment, and the master equipment and the slave equipment can be actively switched through the remote control module.
The improvement of the technical scheme is as follows: the remote control module can switch the storage module from a disk array to a network storage device through a network interface.
