Nutanix has patented a scalable multi-cluster resource sharing facility. The technology involves a global witness process that manages resource requests from nodes across different clusters. Only one request is granted at a time, with others receiving rejections based on stored state values. The system ensures efficient resource allocation in a distributed environment.

A recently granted patent (Publication Number: US11888599B2) discloses a computer-implemented method for managing ownership of shared resources across different fault domains. The method involves receiving a request from a node in one fault domain to become the owner of a resource shared across multiple fault domains, determining the new owner, transmitting authorization to the new owner, and updating the ownership state. The system ensures that storage changes are communicated to relevant nodes in different fault domains, maintaining consistency and efficiency in resource management.

Furthermore, the patent details a method for establishing leadership relationships among multiple requestors contacting the witness process. The process involves acknowledging a single owner of the resource while designating the remaining requestors as followers. Additionally, the system includes measures such as sending periodic liveness signals and conducting liveness checks by followers to ensure the integrity and availability of the shared resource. The method also includes comparing stored state values in a database to maintain accurate ownership states. This innovative approach to resource management across fault domains showcases a robust system for efficient and reliable resource allocation and ownership in complex network environments.
