Global naming for inter-cluster replication

Abstract:

Systems for multi-cluster virtualized computing system management. A method for performing virtual entity replication between source computing clusters and target computing clusters commences upon establishing a virtual entity naming convention that is observed by both the source computing clusters and the target computing clusters. A snapshot from a source cluster is associated with a global snapshot ID before being transmitted to a target computing cluster. At some point in time, the source cluster will initiate acts to replicate a virtual entity to a particular data state that is associated with a particular named snapshot. A second replication protocol then commences. The second replication protocol includes exchanges that serve to determine whether or not the target computing cluster has a copy of a particular named snapshot as named by the global snapshot ID, and if so, to then initiate virtual entity replication at the target computing cluster using the named snapshot.
