Method and system for combining RAID and storage management software system

Abstract

The invention discloses a method for combining an RAID. The method for combining the RAID is applied to a storage management software system. The method comprises the steps of displaying a three-dimensional view of a hard disk in a storage system after an instruction for adding an RAID group is received, wherein the three-dimensional view comprises the position of the hard disk, and the position of the hard disk corresponds to the actual physical position of the hard disk one to one; combining the RAID according to the three-dimensional view of the hard disk in the storage system. As is shown, by means of the method for combining the RAID, in the operation process of selecting the hard disk in the RAID group, the position of the hard disk can be clearly seen through the three-dimensional view of the storage system, which makes it convenient for a user to avoid that the selected hard disks are in the same node with purpose during selection, and the security of data is improved. Meanwhile, the process of selecting the hard disk in the RAID group is more visual, and the difficulty in deploying operation is lowered. The invention further provides a system for combining the RAID and the storage management software system, and the system for combining the RAID and the storage management software system have the same advantages.

Description

technical field [0001] The invention relates to the technical field of multi-disk management, in particular to a method for combining RAID. The invention also relates to a combined RAID system and storage management software system. Background technique [0002] RAID (Redundant Array of Independent Disk, Redundant Array of Independent Disks) technology is to combine a lot of cheap and small-capacity disks into a large-capacity disk group. RAID has a variety of working modes, the typical ones are RAID0, RAID1, RAID5 and RAID10. Users can select the RAID working mode according to actual needs, and then determine the number of RAID groups according to the selected working mode, and then determine the number of each RAID group. The group specifically selects which hard disks in the storage system. The existing software is already capable of selecting and customizing the RAID working mode. [0003] Specifically, in the prior art, when selecting a hard disk in a RAID group, it ...

Problems solved by technology

However, the hard disk recommended by the system algorithm does not take into account the physical location of the hard disk. The recommended hard disk may be located on a node. When the node is powered off, the RAID group will not be available. There are certain risks in data protection and low stability.

However, to select the hard disk through the CLI command line, the operation process is carried out in the background, which is not intuitive and the operation convenience is poor.
