The invention discloses a key value storage system indexing method oriented to an NVM-NVMe SSD (Non-Volatile Memory-Non-Volatile Memory Express Solid State Disk) hybrid architecture, which comprises the following steps of: constructing a heterogeneous storage architecture taking cold and hot data perception as a core driving mechanism, coordinating and managing two types of storage media, namely a non-volatile memory NVM and a solid state disk NVMe SSD, and realizing efficient identification, layered writing and dynamic migration of cold and hot data. According to the method, the characteristics of low delay, durability and byte addressing of the NVM are utilized, the frequency and I / O overhead of Flush and Compaction operations are reduced in a data write-in path, meanwhile, the problem of mixed storage of cold and hot data is avoided, and therefore the overall performance and storage efficiency of a system are remarkably improved. In addition, by introducing an asynchronous migration module, the method can dynamically adapt to the change of data popularity along with time evolution, and effectively support high performance and high availability of the key value system in long-term operation.

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. Based on this, a migration control algorithm based on time-triggered TOPSIS and KM is proposed. 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.
