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.

Method for writing data into flash memory apparatus, flash memory apparatus, and storage system

According to a write data request processing method and a storage array provided in the embodiments of the present invention, a controller is connected to a cache device via a switching device, an input/output manager is connected to the controller via the switching device, and the input/output manager is connected to a cache device via the switching device. The controller obtains a cache address from the cache device for to-be-written data according to the write data request, the controller sends an identifier of the cache device and the cache address to the input/output manager via the switching device, and the input/output manager writes the to-be-written data to the cache address via the switching device.
