Problems solved by technology

[0002] Computers store more and more information, and it is more and more important. In order to prevent accidental loss of data in computers, many important security protection technologies are generally used to ensure data security. The operating loss of equipment, failure of storage media, and operating environment As well as man-made damage, etc., can affect the equipment, resulting in equipment damage and data loss, so that the reliability and stability of the product cannot be effectively guaranteed

Embodiment Construction

[0016] According to the design of the hardware circuit and software level of several aspects involved in the present invention, be divided into following three aspects:

[0017] 1. The two control boards are connected through the backplane using NTB, data mirroring and cache mirroring are performed through NTB, and as a system-level heartbeat link, monitoring the working status of the two mainboards; the two mainboards are connected to the backplane at the same time High-speed connector connections to access and manage all hard drives.

[0018] 2. The two control boards are connected through a serial port as a redundant heartbeat link at the system level. When the NTB fails, the heartbeat link will switch to the serial port link, and the serial port link will detect the working status of the peer board.

[0019] 3. The opposite end restarts the link. When the main board detects that the opposite main board has not responded for a long time, it is considered that the other end...

Abstract

The invention provides a redundant heartbeat link and opposite-end restarting link based double-controller storage system and belongs to the technical field of computer storage. Processors are connected through NTP (non-transparent bridge) and serial-port links, so that data mirroring and cache mirroring are realized and operating states of the processors can be mutually monitored in real time. When one of mainboards breaks down, another mainboard is capable of automatically repairing by restarting an opposite-end mainboard via a restarting link, even if one of the mainboards fails to self-repair, another mainboard also can completely take over all operations of the failed mainboard, and high reliability and stability of storage products are guaranteed.

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to a dual-controller storage system based on redundant heartbeat links and peer restart links. Background technique [0002] Computers store more and more information, and it is more and more important. In order to prevent accidental loss of data in computers, many important security protection technologies are generally used to ensure data security. The operating loss of equipment, failure of storage media, and operating environment As well as man-made damage, etc., can affect the equipment, resulting in equipment damage and data loss, so that the reliability and stability of the product cannot be effectively guaranteed. [0003] With the rapid development of the Internet, electronic finance and other industries, people have higher and higher requirements for the security and stability of network data, and any product has its lifespan, failure and other unstable factors. H...
