Storage resource management method and device

The invention discloses a storage resource management method and device. The method includes the first step of carrying out virtualization on each physical hard disk to generate at least two virtual hard disks corresponding to each physical hard disk, the second step of carrying out combination on at least one virtual hard disk corresponding to each physical hard disk to generate at least two RAID logical units, and the third step of connecting the RAID logical units to a pre-allocated storage area network. Through the method, the virtual hard disks are combined into an RAID, and the combined RAID is connected to the storage area network, so the combined whole RAID will not fail any longer because of local faults of some physical hard disk, and the rank limitation of the RAID is avoided to some extent. In addition, parallelization processing can be carried out on data reconstruction of the RAID through multiple virtual hot standby hard disks, and accordingly the data reconstruction work efficiency is effectively improved.
