Abstract

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.

Description

technical field [0001] The present invention relates to the technical field of network storage, in particular to a method and device for managing storage resources. Background technique [0002] A storage area network (Storage Area Network, SAN for short) storage device is widely used as a storage system in the field of data storage. It provides a block device interface based on the Internet Small Computer System Interface (ISCSI) or the Fiber Channel protocol (Fiber Channel, FC) to the application server on the upper layer. Through the above standard protocol, the storage provided by the SAN storage device can be Resources are included in the entire storage area network for users to use on demand, thereby achieving the purpose of sharing storage resources among users. [0003] In order to improve the availability of SAN storage devices, redundant array of independent disks (Redundant Array of Independent Disks, RAID for short) technology is widely used in storage devices. ...
