The invention discloses a method and a device for mass file access. The method comprises the following steps: obtaining a user name, conducting code computation to the user name and obtaining an integer sequence corresponding to the user name; dividing the integer sequence into two parts, wherein one part is used as a primary directory, the other part is used as a secondary directory of the primary directory and the user name is used as a tertiary directory under the secondary directory; and accessing user data corresponding to the user name under the tertiary directory. By adopting the embodiment of the invention, through the integer sequence corresponding to the user name, the user data can be evenly distributed in a plurality of directories. Moreover, through adopting a multilevel storage method, the user data under each directory is reduced. Thereby, the invention has the advantages that the mass data is supported and the access efficiency is improved.

The invention provides a distributed data access method, a device and a system. The method comprises the following steps: receiving a data access request of users; determining a buffer storage server required by data access; obtaining the data results from the determined buffer storage server; and displaying the results of the data access for the users. The invention solves the problem of visit pressure caused during the visit of a center server by terminal users, and improves the usability of the distributed buffer storage system.
