Problems solved by technology

However, if two controllers belonging to a certain CNP fail at the same time, all disks belonging to the CNP cannot be accessed. Therefore, when a CNP fails, it will directly affect the entire system business, which will lead to the paralysis of the entire storage system, and the business cannot run

Abstract

The invention discloses a storage system, a method for connecting the system and related equipment. The system comprises a disc frame, CNPs and a data exchange center, wherein the disc frame comprises two first uplink interfaces and two second uplink interfaces, two of the four uplink interfaces are directly connected with one CNP, and the other two uplink interfaces are connected with the other CNP; each CNP is connected with two disc frames; the two CNPs connected to the same disc frame backup each other; if two controllers in one CNP fails at the same time, the other CNP takes over all the disc frames belonging to the lower cascade of the failed CNP through the disc frame directly connected with the CNP self, and accesses discs in the taken-over disc frames; and the data exchange center is used for exchanging data between the CNPs. Due to application of the system, the method and the related equipment, the problem that the whole storage system fails after the two controllers in the CNP fails at the same time is solved, and the reliability of rear-end disc access of the multi-control storage system is effectively improved.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a storage system, a connection method of the system and related equipment. Background technique [0002] At present, in the storage system, multiple controllers are mostly used to implement. Every two controllers form a controller pair (CNP, Controller Node Pair). Each CNP is connected to a disk enclosure. The back end of the existing storage system is a disk enclosure. , to expand the storage capacity by cascading disk enclosures. [0003] The data switching center (DSC, DATA SWITCH CENTER) in the existing storage system mainly completes the data exchange between each controller, and usually multiple disk enclosures (DE, DISK ENCLOSUER) are cascaded under each CNP to complete the storage Features of large capacity. The two controllers in each CNP are independent of each other and are mutually redundant, and perform operations such as handshaking and synchronous heartbeat ...
