A data storage method, device and system

Abstract

Embodiments of the present invention provide a data storage method, device and system. The method is as follows: after a control node receives a storage request sent by a client; according to the storage request, a target storage management cluster is determined; Obtain the status information of the target storage cluster from the target storage cluster, and then determine the storage management node in the target storage management cluster in the surviving state according to the obtained status information; and determine the target storage management node from the storage management nodes in the surviving state; request The target storage management node determines a first storage node for storing the target data according to the storage request, so that the client stores the target data in the first storage node. By adopting the solution provided by the embodiment of the present invention for data storage, the control node can obtain the state information corresponding to the storage cluster after receiving the storage request, and does not need to wait, which saves time for data storage.

Description

technical field [0001] The present invention relates to the technical field of resource management, in particular to a data storage method, device and system. Background technique [0002] At present, common data storage systems usually include: control nodes, storage management clusters, and storage clusters. The storage management cluster refers to the collection of multiple storage management nodes, and the storage cluster refers to the collection of multiple storage nodes. The storage management cluster and The storage cluster is connected to each other. Generally, the storage management node in the storage management cluster can be connected to one or more storage nodes in the storage cluster. [0003] The existing data storage process is roughly as follows: the control node receives the storage request for the target data sent by the client, and then allocates a storage management node for the storage request, and stores the above-mentioned target data in the storage n...

[0004] However, if the above-mentioned storage request is received between the start times of two adjacent periods, then the storage request needs to wait until the arrival of the start time of the next period before the control node can allocate the storage request in the surviving state. Storage management node, therefore, using the above data storage method to store data, although the storage of data can be completed, but the allocation of storage management nodes for storage requests needs to wait until the beginning of the cycle arrives, so too much time will be wasted in Waiting, making the data storage time longer
