The invention provides a shingled disk storage method and device, equipment and a medium, the method comprises the steps: acquiring a to-be-stored target object and a shingled disk used for reading and writing, the shingled disk comprising a first storage area only supporting sequential reading and writing and a second storage area only supporting random reading and writing, and the first storage area being provided with a plurality of Zone blocks; creating a root directory for the Zone block in the first storage area and setting root directory information, the root directory information at least comprising a root directory name, a pre-distribution capacity, a retention period and creation time; dividing a to-be-stored target object into a plurality of data blocks, and determining corresponding root directory information according to the number of the data blocks of the target object; under the root directory information, storing the data blocks corresponding to the target object sequentially according to the rule that the data blocks of the same retention period store the same Zone block until the data blocks corresponding to the target object are completely stored; and the data storage mode used by the application avoids data migration and improves the space utilization rate.
Description
technical field [0001] The present application relates to the technical field of data storage, in particular to a shingled disk storage method, device, equipment and medium. Background technique [0002] Shingled Magnetic Recording (SMR, Shingled Magnetic Recording) technology is to partially overlap adjacent tracks like roof tiles, eliminating the gap between tracks, thus increasing the number of tracks that can be accommodated on each disk surface , so that the magnetic recording density is greatly increased, so that the capacity of the magnetic disk can be greatly increased without changing the physical size of the magnetic disk. [0003] Shingled disks separate the stored data and metadata. Data is written sequentially to the S-Zone of the SMR disk, and metadata is written to the C-Zone. C-Zone, like traditional disks, supports random read and write and sequential read and write, but the capacity accounts for about 1% of the total disk capacity. If there is a lot of me...
