This application discloses a method, apparatus, device, and storage medium for dynamic isolation and allocation of virtual network addresses, relating to the field of virtual internet technology. The method includes receiving resource request information from a user, determining the currently allocated target virtual network address, and then determining the target network access zone where the target virtual network address resides; obtaining the target tenant identifier corresponding to the target network access zone; and accessing resource information under the target tenant associated with the target tenant identifier through the resource request information. By establishing the correspondence between the target virtual network address, the target network access zone, and the target tenant identifier, the method solves the problems of missing tenant isolation and inefficient fault recovery in related technologies, thereby achieving technical effects such as improved fault recovery efficiency, reduced data leakage risk, and enhanced data security.

The invention provides a data recovery method and device of a storage system, electronic equipment and a storage medium, and relates to the technical field of distributed storage. The free storage space is used for generating a locally optimized redundant data block which coexists with an original redundant data block of the data object and can recover data in a smaller fault domain range, and when a storage fault is detected, the corresponding redundant data block is selected and called according to the fault range to execute recovery operation. The problems that in the prior art, due to the fact that the locality of erasure codes is insufficient and the fault domain range of original redundant data block recovery data is large, data needs to be accessed across multiple nodes during fault recovery, the transmission amount is large, the recovery speed is low, and the system load is high can be solved, and the purposes of optimizing the locality of the erasure codes, flexibly adapting to different fault scenes and improving the recovery efficiency are achieved. And the cross-node data transmission overhead is reduced, the fault recovery efficiency is improved, and the overall load of the system is reduced.
