Abstract
Embodiments of the present application provide a method for reading and writing video data in a NAS device. The NAS device is mounted to a block interface of a storage server and includes a plurality of data files, and the correspondence between disk block numbers of block devices and filenames of the data files in the NAS device is stored in the index server. In the present application, a reading or writing request sent by the client device is received, a filename of a data file which data is to be read from or written into is located, and then a reading or writing operation is performed in the data file corresponding to the determined filename in the NAS device. In the present application, a reading or writing operation on a block device is transformed into a reading or writing operation on a data file in a NAS device so that a video cloud storage system can support the NAS device.
