Embodiment Construction

[0045] figure 1 It is a block diagram of the data storage device structure. It consists of input\output ports, input control modules, and output control modules. It completes internal\external state monitoring feedback, storage method calculation, storage control, correctness verification, and aggregate input functions to ensure different types Reliable storage of data.

[0046] figure 2 It is the logical structure diagram of the input control module of the present invention. The input control module is composed of data reception, external environment status acquisition, data storage status acquisition, reliability requirement configuration table, storage method calculation, storage method maintenance, data feature matching, input buffer, and storage control sub-modules. The data receiving sub-module receives data from the input port. While sending the original data to the input buffer, it extracts the type and size of the input data and sends it to the data feature matching sub...

Abstract

The invention relates to a feedback-based dynamic hierarchical data storage equipment reliability ensuring method under the condition of dynamic change of the external environment state and internal data storage state. The technical scheme is that: the external environment state and the internal data storage state are monitored in real time, and monitoring results are fed back to an input control module; and the input control module maintains a dynamic change storage mode mapping table according to the monitoring results and the preset reliability requirement of multiple kinds of data, and dynamically adjusts the storage modes of the multiple kinds of data. Due to the hierarchical processing mode, the method can reduce the data storage cost to a large extent.

Description

Technical field [0001] The invention relates to a highly reliable information storage mechanism, in particular to a feedback-based dynamic hierarchical data storage reliability guarantee method under the condition of dynamic changes in the external environment state and the internal data storage state. Background technique [0002] Data storage equipment is the core component of electronic equipment such as computers. It stores programs and various user data that realize the functions of the equipment. Its reliability is directly related to the reliability of the entire electronic equipment. [0003] With the continuous development of electronic information technology, the device density of data storage devices such as magnetic disks continues to increase, and the operating voltage continues to decrease, resulting in the continuous increase of sensitivity of these data storage devices to temperature and radiation. Although the production technology of data storage devices is also c...
