ABSTRACT:
A meta data server100, a user node200and a storage device300are connected together via a Fibre channel10and a LAN20to configure a NAS over SAN system. The user node200sends out a request to access the data in each file. The file is stored in the storage device300in blocks of default size. The meta data server100informs the user node200of the block number where the file to be accessed is stored based on meta data in which relationship between a file and a block is recorded. Prior to this processing, the meta data server100instructs the storage device300to cache the data in advance. This application enables the storage device300to provide the data promptly in response to read request from the user node200.
