[0002] The expansion of the amount of data leads to a continuous increase in the demand for storage space, and the use of storage resources is not used up immediately, but increases gradually or spirally. Therefore, when the actual use of user storage resources is less, but the overall capacity has been allocated, How to improve the utilization rate of existing storage resources, delay the time to add new storage resources, and reduce costs is a difficult problem for enterprise development when new storage resource allocation applications cannot be satisfied and new storage resources need to be added. one

Embodiment
[0015] The method for improving storage resource utilization by dynamic expansion in the SAN storage system of the present invention includes a SAN storage system. In the SAN storage system, dynamics in the Logical Volume Manager (LVM) mechanism based on the Linux system Expansion technology dynamically allocates and recycles limited storage resources according to the actual storage capacity used to improve the utilization of system storage resources. The system structure includes: storage capacity initial allocation module, storage resource usage monitoring module, storage capacity dynamic allocation and Recycling module; the storage capacity initial allocation module counts the storage resources in the SAN storage system, that is, the capacity of all the logical volume groups (Volume Group, VG) in the SAN storage system, and then according to the storage capacity requested by the client, in the logical volume group Logical Volume (LV for short) is created on the system; the st...

The invention discloses a method for increasing the use ratio of storage resources through dynamic expansion in a SAN (Storage Area Networking) storage system, belonging to the technical field of the SAN storage system. The structure adopted by the method comprises the SAN storage system. In the SAN storage system, based on a dynamic expansion technology in a logical volume management mechanism of a Linux system, the limited storage resources are dynamically distributed and recovered according to the actually used storage capacity, and the use ratio of the storage resources of the system is increased. The system structure comprises a storage capacity initial-distribution module, a storage capacity use monitoring module and a storage capacity dynamic-distribution and recovery module. Compared with the prior art, the method for increasing the use ratio of storage resources through dynamic expansion in the SAN storage system has the characteristics of reasonable design, simple structure, easiness in processing, small size, convenience in use, one substance with multiple purposes and the like.
Description
Technical field [0001] The invention relates to the technical field of SAN storage systems, in particular to a method for improving storage resource utilization in a SAN storage system through dynamic expansion. Background technique [0002] The expansion of data volume has led to an increasing demand for storage space, and the use of storage resources is not used up immediately, but gradually increases or spirals. Therefore, when users actually use less storage resources, the overall capacity has been allocated. As a result, the application for allocation of new storage resources cannot be satisfied and new storage resources need to be added. How to increase the utilization rate of existing storage resources, delay the time for adding new storage resources, and reduce costs, is a problem facing enterprise development one. Summary of the invention [0003] The technical task of the present invention is to provide a method for providing users with a storage capacity larger than ph...
