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.

Abstract: A method for adaptively managing a solid state drive (SSD), an associated apparatus, and an associated computer program product are provided, where the method includes the steps of: monitoring whether any deletion event regarding a file system established on the SSD exists, to selectively update a deletion amount accumulation value, where the deletion amount accumulation value represents a total deleted data amount of at least one deletion event of the file system; and after the deletion amount accumulation value reaches a predetermined deletion amount accumulation threshold value, sending at least one TRIM command to the SSD, to allow the SSD to recycle reusable storage space by utilizing a garbage collection mechanism of the SSD.

Abstract: A method for performing cache management for a storage system and an associated apparatus are provided, where the storage system includes a plurality of storage devices. The method includes: utilizing a storage device of the plurality of storage devices as a cache of another storage device of the plurality of storage devices, in which an access speed of the storage device is higher than that of the other storage device, and the cache includes a plurality of cache blocks; and when a read miss of the cache occurs, reading data corresponding to at least one cache block from the other storage device to store the data into the cache, in which a data amount corresponding to the read miss is less than a data amount of each cache block of the plurality of cache blocks.

Abstract: A method for waking up a plurality of hibernated mass storage devices is disclosed. The method includes receiving a first command from a control circuit for accessing data stored in a plurality of hibernated mass storage devices; dividing the plurality of hibernated mass storage devices into a plurality of mass storage groups; waking up a first mass storage group of the plurality of mass storage groups; and notifying the control circuit to stop sending commands to the remaining hibernated mass storage devices in a period of time.

Abstract: A device power is supplied for running a storage device. When a device error occurs, a recovery operation is performed on the storage device. When the recovery operation fails, the device power is reset in a compatibility verification operation and the recovery operation is performed again on the storage device.

Abstract: At startup of an apparatus including a memory and an operating device, an operating system is loaded to the memory as an operating system. While an idle time of the operating device exceeds a predetermined time, the loaded operating system cuts power to the operating device so that the operating device can be completely shut down. As a result, power consumption of the operating device is significantly reduced.
