Embodiments of the present disclosure relate to an apparatus and method for facilitating access to data in a distributed storage system by using a processing unit configured to collect information related to running status of the distributed storage system; obtain metadata related to data stored in the distributed storage system; in response to a request from a client, provide to the client the information related to running status and metadata related to data to be accessed; and extend storage nodes in the distributed storage system so that the client can directly access the storage nodes by using the information related to running status and the metadata related to data to be accessed. Other embodiments are also disclosed.

Facilitating access to data in distributed storage system

A method and apparatus for managing network attached storage that includes detecting frequency of access from a client to a data item that is in a first server in the network attached storage, a global namespace of the network attached storage indicating an access address for accessing the data item, the access address including a first address of the data item in the first server; in response to the frequency being higher than a predetermined threshold, copying the data item from the first server to a second server in the network attached storage which is proximate to the client, so as to form a data image; and updating the global namespace so as to add to the access address a second address of the data image in the second server whereby the data access efficiency of the network attached storage can be considerably improved.
