Patent number: 11917003Abstract: Examples disclosed herein relate to propagating changes made on a file system volume of a primary cluster of nodes to the same file system volume also being managed by a secondary cluster of nodes. An application is executed on both clusters, and data changes on the primary cluster are mirrored to the secondary cluster using an exo-clone file. The exo-clone file includes the differences between two or more snapshots of the volume on the primary cluster, along with identifiers of the change blocks and (optionally) state information thereof. Just these changes, identifiers, and state information are packaged in the exo-clone file and then exported to the secondary cluster, which in turn makes the changes to its version of the volume. Exporting just the changes to the data blocks and the corresponding block identifiers drastically reduces the information needed to be exchanged and processed to keep the two volumes consistent.Type: GrantFiled: October 2, 2020Date of Patent: February 27, 2024Assignee: VMware, Inc.Inventors: Richard Spillane, Yunshan Luke Lu, Wenguang Wang, Maxime Austruy, Christos Karamanolis, Rawlinson Rivera

Patent number: 10515192Abstract: Processing in an asymmetrically distributed file system may include storing first data representative of the content of the files in a file system volume among a plurality of storage nodes. Second data representative of attributes of the files in the file system volume may be stored in only one of the storage nodes. Time-limited leases allow clients direct access to the plurality of storage node in order to access portions of the file system volume. The time-limited leases may be provided to client lessors. Snapshots of the file system volume may be generated after sending a revocation to the client lessors to revoke time-limited leases provided to the client lessors and having received the acknowledgements of the revocations or after the leases have expired for non-responding lessors, to ensure that changes are not made to the file system volume during snapshot processing.Type: GrantFiled: February 2, 2016Date of Patent: December 24, 2019Assignee: VMware, Inc.Inventors: Wenguang Wang, Luke Lu

Patent number: 10419498Abstract: Examples perform input/output (I/O) requests, issued by a plurality of clients to an owner-node, in a virtual storage area network (vSAN) environment. I/O requests are guaranteed, as all I/O requests are performed during non-overlapping, exclusive sessions between one client at a time and the owner node. The owner node rejects requests for simultaneous sessions, and duplicate sessions are prevented by requiring that a client refresh its memory state after termination of a previous session.Type: GrantFiled: December 1, 2015Date of Patent: September 17, 2019Assignee: VMware, Inc.Inventors: Eric Knauft, Luke Lu, Wenguang Wang, Pascal Renauld, Radu Berinde, Ruocheng Li

Patent number: 10114163Abstract: An optical component with image compensation is formed by a plurality of optical fibers arranged and connected in the same direction. A section of the optical component includes an output face, an input face, and a lateral face. The output face is formed by sections at one end of the optical fibers respectively, and each of the sections is a perfect circle or a regular polygon. The input face is formed by sections at the other end of the optical fibers respectively, and each of the sections is noncircular or is a irregular polygonal. The lateral face extends in the same direction as the optical fibers.
