Problems solved by technology

When peer-to-peer storage is used, the failure rate is reduced, but the fault recovery time cannot be reduced, because files can only be restored serially, and the recovery time may be longer; when random storage is used, the fault recovery time can be effectively improved, but Reasonable system parameters need to be designed to balance the failure rate and recovery time to optimize system data reliability. Currently, there is insufficient research on the optimization of this type of storage mode

Embodiment Construction

[0053] figure 1 Is the general flowchart of the present invention.

[0054] 1. Use the distributed storage and parallel recovery method of multiple copies of files to store and restore large-scale archived files.

[0055] 2. Design a continuous-time Markov model to describe the failure recovery process of large-scale archival storage systems.

[0056] 3. Obtain storage system optimization parameters according to the Markov model.

[0057] 4. Construct a large-scale archival storage system based on storage system optimization parameters.

[0058] figure 2 It is a schematic diagram of the first step of the present invention that includes three copies of files distributed randomly across multiple nodes. figure 2 There are N (N=9) nodes in total, forming a storage cluster. n (n=9) files (blocks numbered 0-8, each file has K=3 copies) are randomly and evenly distributed among N nodes, and the nodes are independent of each other. This storage mode has at least the following ...

Abstract

The invention discloses a building method of a large-scale and high-reliable filing storage system. The technical problem to be solved is to provide a large-scale filing storage system and improve the reliability of the filing storage system on the basis of filing data. The technical scheme is as follows: adopting the multi-copy distributed storage and parallel recovery methods of files to store and recover the large-scale filing storage system, designing a continuous-time Markov model to describe the fault recovery process of the large-scale file storage system so as to obtain optimized parameters of the large-scale filing storage system according to the Markov model, and finally building the storage system according to the obtained optimized parameters. The model of the invention is simple, lowers the difficulty of building the high-reliable filing storage system and improves the reliability of the filing storage system, and the built storage system has extensible structure and high cost performance.

Description

technical field [0001] The invention relates to a method for constructing a storage system in the field of computer application technology, in particular to a method for constructing a large-scale and highly reliable archiving data storage system based on a computer cluster system. Background technique [0002] Large-scale archival data storage applications involve many fields such as network security management, network search, communication, finance, and scientific experiments. For example, in network security applications, real-time storage, query and analysis of network communication packet header information is a common network security management method. Generation, the generation speed is fast (the number of messages generated by an ordinary Gbit network connection can reach 100,000 per second, and its data speed can reach tens of MB per second), so the formed system has a large scale. Similar applications include: in the network search engine, it is necessary to pro...
