File processing method and file processing device

Abstract

The invention provides a file processing method and a file processing device. The file processing method comprises the following steps: dividing the data nodes of a distributed file system into a plurality of partitions according to a preset partitioning strategy, wherein the partitions comprise a permanent service partition, a current service partition and a plurality of closed partitions in an energy-saving state; the permanent service partition and the current service partition are in an operating state; and the permanent service partition is used for storing a file with the access frequency exceeding a preset access threshold; when the file is accessed by a user, providing data access service by the permanent service partition; and when a newly-built file request sent by the user is received, storing a newly-built file into the current service partition. Except the permanent service partition and the current service partition in the operating state in the embodiment of the invention, the other partitions are in the energy-saving state, so that the power consumption can be reduced, and the goal of controllable power consumption is reached under the precondition that normal use of the user is not influenced.

Description

Technical field [0001] This application relates to the field of computer storage technology, and in particular to a file processing method and device. Background technique [0002] Generally, the power consumption of a storage server is large, and a storage server can reach 700 to 800 watts. For a relatively large distributed file system, its power consumption is very considerable. At the same time, in many application fields such as video surveillance, data access by users usually has the following characteristics: the amount of data is very large, many storage servers are required, and the access frequency after data is written is very low. For these applications, if all the servers in the system are running, the power consumption will be very large, resulting in considerable economic overhead, and even the power supply of some computer rooms may not meet the system operation requirements. [0003] The disadvantages of the existing technology are: [0004] Currently, distributed ...
