Problems solved by technology

With this boot mechanism, the application layer needs to wait for the completion of data writing before proceeding with the boot process, resulting in a large amount of system boot time spent waiting.
It has been verified by experiments that during the boot time of about 30 seconds, the system waits for queuing to write data to the disk for about 8 seconds, which greatly delays the system boot time

Abstract

The invention discloses a method and device for writing data to a disk through a cache during starting up. The method comprises the steps that in the executing process of a starting-up procedure, a data writing request sent by an application layer to the disk is intercepted, and data corresponding to the data writing request are stored into the cache; a data writing success response is returned to the application layer to allow the application layer to continue to execute the starting-up procedure according to the response; when the disk is detected to be idle, the data in the cache are written into the disk. According to the method and device for writing the data to the disk through the cache during starting up, in the starting-up procedure executing process, the data which originally need to be written into the disk are written into the cache, and the data writing success response is immediately fed to the application layer at the same time, time of the application layer for waiting the response is saved, the starting-up procedure standards are met, and influences cannot be caused on later system operation.

Description

technical field [0001] The invention relates to the technical field of computer system optimization, in particular to a method and a device for writing data to a disk through a cache during startup. Background technique [0002] In the existing computer system, in order to maintain data consistency, there is the following boot mechanism: when the application layer wants to write data to the disk, it sends a write data request to the disk, and queues the write data to the disk according to the write data request. The required data; during the data writing process, the system waits until the data to be written is completely written to the disk, and then responds to the application layer; the application layer can continue to execute the boot program after receiving the response. With this booting mechanism, the application layer needs to wait for the completion of data writing before proceeding with the booting process, resulting in a large amount of system booting time spent ...
