Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0032] The application topology of the dual-controller and active-active storage control system is as follows: figure 1 shown. The application server is connected to the storage control system through a storage area network (Storage Area Network, SAN), and uses the block-level data storage service provided by the storage system. At present, the basic construction methods of SAN network include IP, FC, IB and other networks.

[0033] Such as figure 1 As shown, the dual-control active-active storage control system includes two completely independent and identical storage con...

Abstract

The invention discloses a double-control double-active storage control system and a method. The double-control double-active storage control system comprises two storage controllers and further comprises a magnetic disk cabinet which is connected with the two storage controllers, wherein each storage controller comprises a storage resource management module and a cache module. The storage controllers receive requests of an application server, and flash corresponding caching data in the cache modules to the magnetic disk cabinet with a magnetic disk array stripe as a unit, or read data in the magnetic disk cabinet to the cache modules with the stripe as the unit. Occupied magnetic disk cabinet resources are released after completion of flashing or reading. According to the double-control double-active storage control system and the method, due to the fact that the storage resource management granularity is refined, simultaneous reading and writing of the two controllers are achieved from a macroscopic view. Transmission buses and computing resources are fully utilized, and the storage performance is improved. Furthermore, due to the fact that a novel storage resource management mode is adopted, the use ratio of bus resources of the double controllers and the computing resources is improved, the storage performance and volume are improved, and the switching time of storage system breakdown is lowered.

Description

technical field [0001] The invention relates to the field of computer systems and storage, in particular to a dual-control dual-active storage control system and method. Background technique [0002] The dual-control storage system is an effective way to ensure data reliability, and it is also the preferred solution for data storage of small and medium-sized enterprises. Firstly, the dual-controller storage system can provide 7*24 hours of business support through the two controllers, and secondly, the dual-controller storage system can realize the load balancing function of the two controllers. [0003] Most of the current dual-control storage system design adopts the exclusive management mode of storage resources, that is, for the same storage resource to be occupied by the same controller within a certain period of time, the data read and write of the other controller needs to forward the data to this controller , the actual read and write functions are completed by this...
