Cascading method and equipment for storage devices

Abstract

The invention provides a cascading method for storage devices, and is applied to a video monitoring network composed of a display manager (DM), at least one electric computer (EC) and a plurality of storage devices. Each of the storage devices comprises at least two extended ports, is connected with other storage devices through the extended ports, and saves service configuration of the other storage devices. When one storage device has a failure, another storage device takes over the failure storage device after receiving an instruction from the DM, and supplies service for the EC according to the saved service configuration of the failure storage device. The invention also provides the storage device and the DM based on the same thought, and users can use the existing storage devices fully to solve the problem of storage administration and distribution, and high reliability is achieved.

Description

technical field [0001] The invention relates to the cascading of storage devices, in particular to the cascading technology of the storage devices under the network environment of video monitoring. Background technique [0002] With the continuous development of network technology and digital video technology, digital video technology has been developed rapidly and widely used. In application scenarios that have high requirements for video quality, such as city security and toll checkpoints, low-definition SD video technology can no longer meet the needs of user services. The emergence of high-definition high-definition digital video technology caters to users' needs for continuous improvement in video quality. High-definition digital video technology has become the development trend of network digital video technology. [0003] With the increasing maturity of high-definition digital video technology, the amount of data storage will usher in a period of great growth. Due to...

Problems solved by technology

[0007] The first method is to replace the existing disk to increase the storage capacity. There is a process of copying the data in the replacement disk to the new disk, which will affect the processing capacity of the existing business to a certain extent. At the same time, the replaced disk will not be able to use, requires a lot of money

[0008] The second method of adding a new storage device. In the existing solution, the newly added storage device and the original device work independently without information interaction with each other, and the storage resources owned by each storage device cannot be effectively integrated. Together, only the checksum calculation of the respective device array data is completed, and the administrator may also need to perform manual configuration and other operations
