Embodiment Construction

[0019] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. 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 with each other.

[0020] figure 1 Shown is the processing flowchart of the dual-controller-based storage management method in Embodiment 1 of the present invention, including the following steps:

[0021] Step 101: the command parsing module in the main controller parses the received service request, determines the service request type, and sends the service request type to the cache module in the main controller;

[0022] Further, before the instruction parsing module in the main controller parses the received service request, it also includes: the application server sends the service request to the main controller.

[0023] Further, the service request type includes: write data request, read data request.

Abstract

The invention provides a storage management method and system based on dual controllers. The method comprises the following steps: an instruction analysis module in a master controller analyzes a received service request, the type of the service request is determined, and the type of the service request is sent to a caching module in the master controller; and the caching module in the master controller determines a corresponding data processing strategy according to the type of the service request to realize the synchronization of cached data among multiple controllers and improve the reliability of a multi-controller storage system.

Description

technical field [0001] The invention belongs to the field of network storage, and in particular relates to a storage management method and system based on dual controllers. Background technique [0002] The prior art discloses a cache management method of a dual-control storage server. In the ISCSI network storage server architecture, cache management is performed on the dual-control storage server, and a continuous space is divided from the memory managed by the Linux system as an independent cache module. The independent cache module is evenly divided into multiple cache blocks, and the physical disk is evenly divided into multiple disk logical blocks. One cache block can map the data of any disk logical block, mark the state of the cache block, and use a two-way circular linked list to manage the free space separately. Caching blocks and using cache blocks. [0003] Although the above solution discloses that an independent cache module is set in the dual-control storage ...
