Title: DATA STORAGE METHOD AND DEVICE
Abstract:
An embodiment of the present application provides a data storage method and device, and the method comprises: receiving a data write request sent via a client by a first tenant; determining, according to the data write request and a storage permission of the first tenant with respect to each RZ (Resource Zone) in multiple RZs, at least one RZ usable by the first tenant from the multiple RZs; determining, according to the data write request and a first data distribution policy, a distribution of N copies in the at least one RZ; and respectively storing, according to the distribution of the N copies in the at least one RZ and a second data distribution policy, the N copies in at least one node corresponding to the at least one RZ. By using different combinations of data distribution policies, the data storage method and device in accordance with the embodiment of the present application can be used to flexibly control the distribution in nodes for tenant data required to be stored, thus reducing the complexity of strategic deployment.
