AI Technical Summary

Problems solved by technology

When the IO random characteristic is determined as random IO, due to the non-linear characteristics of random IO, the specific position of the IO that may be read in the later period cannot be predicted by using the existing method, so the data pre-reading of random IO cannot be realized.

Abstract

The invention discloses a data prereading method and device. The data prereading method includes training a single-hidden layer neural network to obtain a multi-hidden layer neural network with preset layers; subjecting the trained multi-hidden layer neural network with the preset layers to prereading the data of a storage system to the cache. In this way, random IO (input-output) data prereading is achieved, data prereading accuracy is guaranteed in the cache, and storage system performance is improved.

Description

technical field [0001] The invention relates to computer technology, in particular to a method and device for realizing data pre-reading. Background technique [0002] With the development of computer technology, the storage system has gradually migrated from the computing system and gradually formed an independent device. Today, the entire computing system can be considered to be composed of three parts: computing nodes, switching nodes, and storage nodes. With the increase of computing capacity of computing nodes, higher and higher requirements are put forward for the performance of storage nodes, and the storage system is the main form of storage nodes. Among the storage media, the overall performance of ordinary mechanical hard disks is generally low due to the influence of the mechanical structure. Generally, the number of read and write operations per second (IOPS) is about 100, and even enterprise-level high-speed mechanical hard disks will not exceed 200 IOPS. Ther...
