Problems solved by technology

However, this implementation method will reduce the performance of the storage system, because when the system starts running, the number of garbage blocks in the storage system is very small. If garbage collection is started at this time, the garbage collection thread will be used for data monitoring and migration , will occupy a large amount of CPU resources, resulting in waste of resources, and the write amplification reduction of the storage system will not have a great effect

Abstract

The invention discloses a junk information recovery method which comprises the following steps: when a power-on signal is received, starting a data block monitoring thread; performing real time monitoring on the number of system idle blocks through the data block monitoring thread; controlling the starting number of garbage collection threads according to the number of the system idle blocks so asto collect garbage information through the started garbage collection threads. The junk information recovery method can reduce system resource waste and improve system reliability on the premise thatsystem operation efficiency is not affected. The invention further discloses a junk information recovery device and equipment and a computer readable storage medium which all have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of storage software, in particular to a garbage information recovery method, and also to a garbage information recovery device, equipment, and computer-readable storage medium. Background technique [0002] The rapid development of science and technology has driven the development of the Internet. In the Internet era, Internet data is also increasing exponentially, but not all of these data are useful data. There are a lot of spam information, such as duplicate data, fault data, suspicious data etc. Therefore, garbage collection technology came into being. [0003] The so-called garbage collection means that in the all-flash storage system, in order to reduce the write amplification of the back-end SSD (Solid State Drives, solid state drive), the storage system will actively perform garbage collection, and the data on the data block with a low usage rate will be appended Data migration is perform...
