Embodiment Construction

[0033] The present invention will be further explained below in conjunction with the embodiments and accompanying drawings, but this should not be used as a limitation to the protection scope of the present application. Introduction to related concepts:

[0034] (1) Stripes: The concept of strips is proposed along with the RAID technology. Striping technology is to automatically divide the continuous data written to the disk into many small parts and store them on different data disks.

[0035] For example, assuming that there are 5 disks, if they do not form stripes and only write data sequentially, the disk data storage is as follows: figure 1 shown. If stripes are formed (taking RAID5 as an example), the data storage is as follows figure 2 shown. figure 1 and figure 2 Among them, 0, 1, 2, 3..., 39 represent addresses written sequentially. If you do not use RAID technology, such as figure 1 , each disk is stored sequentially, and only one disk is turned on at a time...

Abstract

The invention discloses a soft and hard synergic dynamic load storage method. The method comprises the steps of adopting a cold and hot tree in a data disk layout for recording disk strips, and dynamically allocating the disk strips. The energy is saved on the condition that the requirement for data transmission bandwidth is met, the xor computing part which is originally conducted through a CPU is achieved through an FPGA hardware algorithm, and the method is very suitable for a large-sized storage system for dynamic load change. According to the method, a novel disk layout mode is adopted and combined with hardware to be in charge of dynamic storage in the software and hardware combination mode, an opened disk is more reasonably utilized, the extra energy consumption brought by conversion of the disk is reduced, the address computing part is achieved through a software algorithm, the xor computing part is achieved through hardware, the disk energy consumption and the CPU resource when the data is stored are reduced, and the performance of an entire RAID storage framework is improved.

Description

technical field [0001] The invention relates to a dynamic load data storage method (DSSH), in particular to a software-hardware cooperative dynamic load storage method. Background technique [0002] With the popularization and rapid development of the Internet, the total amount of data is increasing exponentially. Efficient storage, management and use of data has become the focus of all walks of life. The requirements for all aspects of the storage system are unprecedentedly high. . With the development of storage technology, information storage systems have been significantly improved in terms of high availability, high performance, scalability, and low cost. [0003] With the explosive growth of data, the cost of storage devices has increased sharply, and the requirements for data security have become higher and higher. How to store, manage and use data efficiently has become an issue of increasing concern to enterprises. Traditional RAID disks Storage of data in arrays ...
