Abstract

The invention discloses a solid state disk using method, system and device and a storage medium. The method comprises the steps: receiving a report zone request; applying for a target storage space; continuously selecting the zone info meeting the request of the report zone until the stop condition is met; when the part outside the reserved area of the target storage space is not fully filled, continuously placing the zone info; after the part outside the reserved area is fully filled, placing continuously selected zone info by using P sequentially applied storage spaces until a stop condition is satisfied; for any one storage space, when the storage space is full and a stop condition is not satisfied, uploading the data in the storage space to a host and applying for the next storage space; and after the stop condition is satisfied, filling the information header into the reserved area and uploading the information header to the target storage space. By applying the scheme of the invention, the time consumption for obtaining zone information is reduced.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a method, system, device and storage medium for using a solid-state hard disk. Background technique [0002] ZNS (Zoned Namespaces, partition namespace) is a solution based on the NVMe (Non-Volatile Memoryexpress, non-volatile storage) protocol. , the advantage of low cost. Usually ZNS SSD only supports sequential writing, so before ZNS SSD is configured and used, it is necessary to obtain the configuration information of each zone required inside the ZNS SSD, and then accurately determine the write pointer and status of each zone. The command is report zone, which is implemented based on the zone management receive command in the ZNS protocol. [0003] At present, there is no ZNS SSD based on the ZNS protocol in the market, and the ZNS protocol is still being perfected. The process of obtaining zone information through the report zone command currently takes a long t...
