Abstract

The invention discloses a data storage method. The method comprises the steps of determining the target data according to a data instruction; judging whether the target data is stored in an HDD or not; if yes, judging whether the target data is hotspot data or not; if so, storing the hotspot data into an SSD. According to the data storage method, the support degree of the storage system for the hotspot data can be more effectively improved, so that the performance of the cluster SSD is brought into full play, the availability of the SSD is improved, and the overall performance of the system isfurther improved. The invention further discloses a data storage device, a data storage system and a computer readable storage medium which all have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of computer storage, in particular to a data storage method, and also to a data storage device, system and computer-readable storage medium. Background technique [0002] With the rapid development of cloud computing, cloud storage and other technologies, the distributed storage system has ushered in a stage of rapid development. In order to adapt to different business scenarios, the distributed storage system is constantly improving and developing in terms of functions and performance. With the acceleration of the storage medium, the architecture of the distributed storage system has also developed from the previous single HDD (Hard Disk Drive, hard disk drive) to HDD+SSD (Solid State Drives, solid state drive), and full SSD. However, the current distributed storage system for the more common HDD+SSD framework is not friendly enough to support data hotspots, and there is no special function to identify hots...
