Abstract

The invention provides a method and a system for storage media access as well as a method and a system of data access and operation. The processing method of storage media contains the steps as follows: step (A), set virtual address comparison table of physical storage media and record physical storage media collection, physical storage media and corresponding relation among virtual storage media; step (B), add device identification of physical storage media to corresponding units of virtual address comparison table; step (C), create virtual storage media device object corresponded with physical storage media collection, and register to driver module of virtual SCSI port. The device identification of virtual storage media will be recorded in the corresponding units of virtual address comparison table. Fourthly, virtual SCSI port driver module registers device object of virtual storage media to operation system. The invention has the advantages of efficient application in physical storage media and storage thermal dilatancy, reduces storage investment, extends investment cycle, and simplifies storage management.

Description

technical field

[0001] The invention relates to data storage technology, in particular to a method and system for virtualizing computer storage media. Background technique

[0002] Computer data is stored on computer physical storage media. The data storage unit on the computer's physical storage medium is a data block. When data is written into the computer, it is written into a data block with a fixed address, and when needed, the data is read from this data block. The capacity of a computer's physical storage medium is the sum of the capacities of all data blocks on the physical storage medium. The capacity of the physical storage medium presented to the user by the computer is a fixed, actual value determined by the physical storage medium itself.
