This application provides a method, apparatus, electronic device, and storage medium for distributed storage collaborative optimization, relating to the field of computer storage technology. It utilizes a disk array controller to configure multiple physical hard drives within a storage node as virtual disks, then maps these virtual disks to logical volumes of a distributed storage system. Based on these logical volumes, a multi-replica redundancy strategy is employed to construct dual redundancy protection. When a single physical hard drive in the virtual disk experiences a slow disk or fails, the disk array controller initiates and executes a data reconstruction operation within the storage node. Therefore, it can solve problems in existing technologies such as large-scale data reconstruction triggered by single-disk failures due to the reliance on multi-replica redundancy mechanisms in traditional distributed storage, a surge in disk I / O pressure, high operational complexity, a contradiction between performance and reliability, and low fault handling efficiency caused by the immaturity of hardware RAID and distributed storage collaborative optimization.

The present application relates to a hash table reconstruction method, apparatus, computer equipment, and medium. The method is applied to a disk array controller connected to a host computer and including a cache. The method comprises: reading cache status data from a pre-built hash table when the disk array controller is restarted after a power outage; when the status data indicates that the cache is locked and cache operations have not been completed, resetting the status data to reconstruct the hash table to obtain a new hash table; and responding to input and output commands from the host computer based on the new hash table. This method enables rapid response to the host computer even when the disk array controller is restarted after an abnormal power outage.
