Abstract: The invention introduces a method for determining processing nodes for executed tasks, performed by a processor when loading and executing a daemon, and containing at least the following steps: obtaining a first evaluation score associated with usages of I/O devices of a first node by a task in a time interval; obtaining a second evaluation score associated with usages of I/O devices of a second node by the task in the time interval, wherein the task is executed by a processor of the first node; and when the second evaluation score is higher than the first evaluation score, switching execution of the task to a processor of the second node.

Abstract: A method for performing data recovery in a redundant storage system and an associated apparatus are provided. The method includes: determining a state of a cache block of a plurality of cache blocks, in which the plurality of storage devices includes a set of Hard Disk Drives (HDDs) and a set of Solid State Drives (SSDs), an SSD Redundant Array of Independent Disk (RAID) of the redundant storage system includes the set of SSDs, and an HDD RAID of the redundant storage system includes the set of HDDs, in which the SSD RAID is utilized as a cache system of the HDD RAID and includes the plurality of cache blocks; and performing a retry-read operation on at least one of the HDD RAID and the SSD RAID according to the state of the cache block, to obtain a correct version of data within the redundant storage system.
