Embodiment Construction

[0022] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0023] This invention proposes a network storage service system with dual controllers, please refer to figure 1 As shown in , it is a schematic diagram of the architecture of the storage service device of the present invention. The dual-controller storage service device may be composed of an embedded system, or may be composed of multiple computers.

[0024] In this embodiment, an embedded system is used as its description, and the dual-controller network storage service system includes: a client 110 , a network storage device 120 and a control device 130 . The client 110 is connected to the control device 130 through a network. The type of network may be but not limited to Internet (Internet) or internal network (Intranet). The control device 130 extracts or writes files to corresponding network storage devices 120 accordi...

Abstract

The invention provides a load coordinating method of a network storage double-controller. The method includes that a first controller creates at least one multipath device according to a plurality of storage devices of a network storage device; the first controller creates a virtual device snapshot according to a configuration file, wherein the virtual device snapshot belongs to the multipath device; a second controller sends disk application requirements to the first controller so as to obtain one multipath device of the first controller; the first controller releases the to-be-stored multi-path device and the virtual device snapshot after the first controller receives the disk requirements; and the second controller obtains the released storage device, and the second controller creates the multi-path device and the virtual device snapshot according to the storage devices.

Description

technical field [0001] The invention relates to a load coordination method, in particular to a load coordination method of dual controllers of network storage. Background technique [0002] When building an internal storage network, enterprises usually choose Direct Access Storage (DAS for short), Network Attached Storage (NAS for short), and Storage Area Network (SAN for short) to communicate with each other. Matching solutions for storing data. [0003] SAN is to separate many storage devices from the local area network and become another network. The characteristic of SAN is to realize many-to-many high-speed connections between servers and physical storage devices. SAN mostly uses Fiber Channel (Fibre Channel) to connect to the server. The connection method is to install the Fiber Channel card (FC HBA) in the server, then connect to the fiber switch, and finally connect to the physical storage device. [0004] The front-end client and the back-end SAN may be transmitt...
