[0005] For the situation that the remaining storage space of the cloud storage resource pool is not enough to store new data, the above method must passively delete the historical data after receiving the new data. Since the new data has been received, it must wait until the cloud storage resource pool has released enough New data can only be stored if there is enough storage space, which seriously affects the storage efficiency of data.

The embodiment of the invention provides a storage space adjustment method and device of a cloud storage resource pool and a cloud storage system, and the storage space adjustment method of the cloudstorage resource pool is applied to a management server, and comprises the steps: obtaining and recording flow statistical information of the cloud storage resource pool counted by each storage server; predicting the storage capacity required by the remaining storage period according to the recorded historical flow statistical information; judging whether the residual storage space of the cloud storage resource pool is smaller than the storage capacity or not; and if so, adjusting the remaining storage space of the cloud storage resource pool through a preset adjustment storage strategy. Through the scheme, the data storage efficiency can be improved.
Description
technical field [0001] The present invention relates to the technical field of cloud storage, in particular to a storage space adjustment method and device of a cloud storage resource pool, and a cloud storage system. Background technique [0002] Cloud storage system is a system that uses cluster technology, virtualization technology, and distributed storage technology to integrate a large number of different types of storage devices in the network to work together through software to jointly provide data storage and business access functions. The cloud storage system realizes the storage and management of a large amount of data. For example, in the security system, the data volume of the security video is large, and the cloud storage system is often used to store and manage the security video. [0003] The cloud storage system provides multiple storage servers. The storage server is an access storage medium in the cloud storage system and a server that provides storage fun...
