Abstract: A data storage method includes obtaining at least one data record, each data record includes one carrier identifier and at least one label value, the at least one data record is stored in a data table, and the data table is used to record a correspondence between a carrier identifier and a label value; and creating a bitmap index corresponding to the at least one data record, where the bitmap index includes at least one bitmap; each bitmap corresponds to one label value; each bitmap includes at least one bitmap position, and each bitmap position is used to record whether a carrier corresponding to one carrier identifier has a label value corresponding to a current bitmap.

Abstract: A data storage method and a physical server are provided. M virtual machines are deployed on a plurality of physical servers. The M virtual machines are respectively deployed as M data nodes in a distributed storage system. A metadata node in the distributed storage system receives a data storage request of a client, and determines identifiers of N virtual machines from the M virtual machines based on stored grouping information. The grouping information records a mapping relationship between a plurality of anti-affinity groups and identifiers of the M virtual machines.
