This application discloses a solid-state drive (SSD), a bad block screening method, and a computer-readable storage medium. The SSD is designed for use in a wide-temperature environment and includes storage units and a controller. The wide temperature range is -40°C to 85°C. Each storage unit includes storage blocks, and a storage block is identified as a bad block if its read / write error bit flip count exceeds a threshold in the wide-temperature environment. This application requires bad block screening of the target SSD's storage blocks based on the read / write error bit flip count in a wide-temperature environment. This ensures that the ultimately screened bad blocks reflect potential storage problems in the SSD under wide-temperature conditions, thereby improving the accuracy of bad block screening. The bad block screening method and computer-readable storage medium provided in this application also solve corresponding technical problems.

The present invention discloses a Ceph storage system data migration method based on P4 network telemetry optimization. By introducing P4 network telemetry technology, real-time monitoring of network and storage status is achieved, detailed key performance indicators are obtained, and data migration decisions are made fine-grained down to the level of a single placement group based on this information. During the data migration decision-making process, complex network and storage problems are abstracted into a dual-objective optimization problem.

By dividing and controlling time slots, the constrained nonlinear optimization problem is converted into a linear optimization problem controlled by multiple time slots. The correspondence between the outgoing set and the incoming set is determined at intervals. The OSD migrates based on this correspondence, and adjustments are made after the time slot ends. The present invention can enhance the adaptability of heterogeneous storage environments, improve system response speed, and enhance decision-making capabilities.
