METHOD AND DEVICE FOR ALLOCATING RESOURCE OF HARD DISK IN DISTRIBUTED STORAGE SYSTEM

摘要

This application provides a method for allocating a resource of a hard disk in a distributed storage system. The distributed storage system includes a plurality of hard disks. The method includes: selecting a hard disk set from the plurality of hard disks based on a bandwidth requirement and a storage specification of a first user; and creating first logical storage space for the first user from the hard disk set, where the first storage space of each hard disk in the hard disk set provides storage space for the first logical storage space. In the method, a bandwidth lower limit of the hard disk can be ensured.
