Latest Patents

Guruprasad Pattar holds a patent titled "Unmapping logical block addresses of remote asynchronously replicated volumes." This patent focuses on the process of unmapping extents transmitted in delta sets, which are utilized to unmap logical block addresses (LBAs) on remote replicas of asynchronously replicated storage objects. The invention involves a host server sending a SCSI unmap command to a production storage array to unmap a range of LBAs. In response, the production storage array creates an unmap extent that identifies the local and remote replicas, starting LBA, and the number of LBAs to be unmapped. At the end of each asynchronous replication cycle, unmap extents and updated data are sent to a disaster recovery storage array in a delta set that preserves chronological ordering. This process allows the disaster recovery storage array to discard cached data corresponding to the unmapped LBAs and de-allocate the backend storage space. By integrating unmap extents with updated data in delta sets, the invention maintains point-in-time consistency and is more efficient than sending zero data.
