SOFTWARE DEFINED STORAGING METHOD FOR DATA SHARING AND MAINTENANCE ON DISTRIBUTED STORAGE ENVIRONMENT

摘要

The present invention is a combination of RAID and network virtualization technology used in a distributed storage environment. The storage device is configured as software-based virtual storage to provide flexible control and management, as well as to greatly increase the capacity of physical storage and disaster recovery cost And more particularly, to a software definition storage method for data sharing and management in a distributed storage environment. A RAID controller unit for setting up a virtual storage device and for driving a RAID-N (one or at least two mixing levels of N: 0 to 53); and a controller A storage method for data sharing and management in a distributed storage environment in which an error is detected by selecting a storage device, the storage method comprising the steps of: (N: one or at least two mixing levels of N: 0 to 53) when a disk error is detected to set up a virtual storage device, which is a cloud system 31 or a cloud system 31, A RAID-N drive step of selecting a virtual storage device and transferring data of a disk on which an error is detected, and then, when recovery of the error disk is completed, And recovering the data by transferring the disk data to the recovered disk, wherein the step of setting up the virtual storage comprises: setting up a predefined and connected network and encryption; And a step of generating and storing an index table of the set up and authenticated network and the virtual storage device, wherein the RAID-N driving step comprises: And a transmission step of transmitting data of a disk on which an error is detected to the selected virtual storage device, wherein the recovery step of the RAID-N Transmits the disk data of the selected virtual storage device, decodes the index table while decrypting the data And a writing process.
