Abstract

The invention discloses a full flash system metadata placing method. The full flash system metadata placing method comprises the following steps: confirming a node to be placed in a target B+ tree when the metadata stored in the memory reaches a preset placing threshold of the metadata; placing the node to be placed in the form of B+ tree; and recording the placing address of the node to be placed, wherein the node in the B+ tree is the node for storing the metadata. By means of the technical scheme provided by the embodiment of the invention, the nodes to be placed with the metadata are placed sequentially, therefore, the efficiency of metadata reading is greatly improved while ensuring the efficiency of placing, the performance of the full flash system is improved, and the user experience is improved. The invention also discloses a full flash system metadata placing device and equipment and a storage medium, which have the corresponding technical effects.

Description

technical field [0001] The present invention relates to the technical field of magnetic disks, in particular to a method, device, equipment and computer-readable storage medium for storing metadata of an all-flash system. Background technique [0002] With the development of disk technology, SSD hard disks are becoming more and more common. Compared with traditional hard disks, SSD hard disks have greatly improved their capacity and access speed. The reading and writing methods of SSD hard disks are very different from those of traditional hard disks. The back-end disks of the all-flash system SSA all use SSD hard disks. The efficiency of storing metadata to the SSD directly affects the performance of the all-flash system. [0003] In the prior art, the metadata storage is to directly drop the metadata to the SSD hard disk. When it is necessary to read the metadata that has been loaded from the SSD hard disk, it is necessary to verify whether the metadata in the SSD hard di...
