Solid-state disk storage host system log information method, device and equipment and medium

Abstract

The embodiment of the invention discloses a solid-state disk storage host system log information method, device and equipment and a computer readable storage medium. The method comprises: a solid-state disk receives log writing information sent by a host through a preset interaction command interface according to a preset host system log information format; judging whether the available space of the solid-state disk system log storage area is not smaller than the log information occupied space capacity or not; and if yes, writing the log identification information into a first log management data corresponding table item of the log management array, and writing the log file content into a log storage area corresponding to the first log management data corresponding table item. The solid-state disk system log storage area is composed of a plurality of log storage areas; wherein the log management array is composed of a plurality of log management data corresponding table items, and thelog management data corresponding table items uniquely correspond to the log storage area. The method solves the problems that a traditional solid-state disk storage host system is poor in log information performance and low in efficiency.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of solid-state disk storage, and in particular, relate to a method, device, device, and computer-readable storage medium for storing host system log information in a solid-state disk. Background technique [0002] Solid state disk is a new type of storage device based on Nand Flash storage medium. Its control protocol adopts NVMe (Non-volatile Memory Express, non-volatile memory host controller interface specification) standard, which has the remarkable advantages of high performance and low power consumption , due to the limitation of the erasing and writing times of NAND media, if the SSD is used in an unreasonable way, it will affect the service life. [0003] At present, in data centers, SSDs are usually used to run key applications such as large databases, and a large number of system log files need to be saved. Due to the priority of the internal firmware algorithm of the solid s...
