Problems solved by technology

However, a problem in this federation / aggregation is that since the federation / aggregation is distributed in multiple physical locations, when these physical locations are too far apart or the network communication bandwidth between them is not ideal, there may be memory overload The response time of data access becomes longer, and the efficiency of data access decreases, etc.

Abstract

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.

Description

technical field [0001] Various embodiments of the present invention relate to storage management, and more particularly, to methods and devices for managing Network Attached Storage (NAS). Background technique [0002] On the one hand, with the development of data storage technology, various data storage devices have been able to provide users with higher and higher data storage capabilities, and the data access speed has also been greatly improved. On the other hand, the development of network technology has opened up a new direction for data storage. Data storage devices are no longer limited to being deployed locally on data access devices, but can be located in any physical location accessible via the network. [0003] Currently, network attached storage has been developed, which is an emerging data storage technology. According to this technology, storage devices attached to a network can provide centralized data access services to various users connected to the networ...
