Abstract: A flash memory apparatus for controlling storage of data comprises a plurality of blocks for storing data and a controller. Each block includes a plurality of pages. The controller receives first target data and identifies a first block to store the first target data. Then, the controller divides the first target data into two parts. A size of a first part is equal to the available capacity of the first block. And a size of a second part is equal to the size of the first target data minus the size of the first part. The controller further determines a second block that has stored data but is not full. At last, the controller writes the first part into the first block and write the second part into the second block.

Abstract: A storage system includes a host, a check node, and multiple data nodes. The host groups multiple data write requests into multiple data write request sets according to data node identifiers included in the data write requests. Each data write request set includes multiple data write requests having a same data node identifier. When a size of all data write requests in each of a specified quantity of data write request sets reaches a preset data amount, the host calculates check data of the specified quantity of data write request sets. Further, the host sends each data write request set to a data node indicated by an identifier, and sends the check data to the check node. Therefore, data of a same type can be stored in a same storage node and the data can be read from only one storage node, thereby improving data reading efficiency.

Abstract: A solution for processing a stripe in a storage device is provided. Where at least one stripe unit not requiring garbage collection from each stripe of at least two stripes in the storage device is determined, each of the at least two stripes comprises a stripe unit requiring garbage collection and a stripe unit not requiring garbage collection; parity data of data in the determined stripe units not requiring garbage collection is computed and stored into a first idle stripe unit, where the first idle stripe unit and the determined stripe units not requiring garbage collection are in a new stripe in the storage device.

Abstract: Embodiments of the present invention disclose a method and an apparatus for reading and writing data in a file system, which are applicable to the field of communication technologies. In the embodiments of the present invention, the file system supports file-level redundancy algorithm operations of independent disks; after receiving a file read/write request, the file system determines a read/write location of the data to be read/written in the data strip, sequentially caches the to-be-read/written data information corresponding to at least one data strip, and processes the cached data information of at least one data strip. In this way, after the to-be-read/written data information corresponding to a complete data strip is cached, the data is read/written by using a data strip as a unit, and thereby improving efficiency of reading/writing data.
