Embodiment Construction

[0043] The core of the present invention is to provide a data migration control method. In the prior art, when the file classification function is enabled in the distributed file system, data migration is usually carried out without restraint in the background, that is, as long as the preset conditions are met, the data will be transferred. When migrating data, it will inevitably occupy a certain bandwidth of the entire system. In general, however, the bandwidth of the overall system usually has a maximum value. If data migration is performed unrestrainedly in the background, it will inevitably occupy a part of the bandwidth of the entire system, which will reduce the bandwidth available for users to perform normal business, which will affect the normal business of users.

[0044] However, a data migration control method provided by the present invention can determine whether the current system is in a busy state through preset conditions, and if so, delay the task of data mi...

Abstract

The invention discloses a data migration control method. The data migration control method comprises the following steps: acquiring a data migration command; acquiring the current bandwidth of a system; when the bandwidth meets preset conditions, determining whether the system is in a busy state or not; and when the system is in the busy state, after a preset period of delay time, migrating data according to the data migration command. According to the data migration control method, whether the current system is in a busy state or not can be determined through preset conditions, if yes, the data migration task is delayed for a preset period of time, so that the bandwidth of the current whole system, occupied by data migration, can be reduced, normal business of a user has sufficient bandwidth for operation, and accordingly, proceeding of the current business of the user cannot be influenced by data migration. The invention also provides related devices which have the same beneficial effects.

Description

technical field [0001] The invention relates to the field of data migration, in particular to a data migration control method and a related device. Background technique [0002] With the continuous advancement of science and technology in recent years, the application of distributed systems has become more and more extensive. A distributed system usually needs to use a distributed file system to manage files stored in the entire system. [0003] With the growing power of distributed file systems, distributed file systems can classify data at this stage, usually storing infrequently accessed data in high-capacity off-line storage devices, and storing commonly used data in among online storage devices. When reading data, data migration technology will be applied, that is, data will be transferred in different storage devices. [0004] In the prior art, when the file classification function is enabled in the distributed file system, data migration is usually carried out with...
