Network data storing system and data accessing method

摘要

The present disclosure provides a network data storage system and a network data access method. The disclosed network data storage system includes: a data node, used for storing a data unit; a metadata node, used for storing and managing routing information and providing the routing information according to a data processing request of a client; and a data management node, used for processing the requested data unit in the data node according to a data access request of the client. The disclosed system and method may improve access performance of network data, enhance expansibility of a system, and lower expansion cost.

1. A system comprising:
a data node that stores a data unit; and a metadata node that: receives a request for accessing the data unit; obtains information of the data unit from the request for accessing the data unit; obtains an identifier of the data unit based on a mapping relationship between the information of the data unit and the identifier of the data unit, the identifier of the data unit including information of an identifier of the data node and position information of the data unit in the data node; computes the identifier of the data node at least based on the identifier of the data unit; and obtains an identifier of a data management node based on a mapping relationship between the identifier of the data node and the identifier of the management node.
