Abstract: Some embodiments provide a novel method for managing hardware forwarding elements (MHFEs) that facilitate the creation of multiple logical networks on a set of shared physical forwarding elements. The method uses a set of logical controllers that generate data that defines a set of logical networks, and a set physical controllers to distribute the generated data to the hardware forwarding elements. In some embodiments, each MHFE can serve as either a master MHFE or a slave MHFE for one set of computing end nodes (e.g., VMs, containers, etc.) in a logical network. To ensure proper routing of data packets to the computing end nodes, each MHFE sends to its physical controller an inventory (e.g., a table, a list, etc.) of the set of computing end nodes for which it serves as the master MHFE or the slave MHFE. Each physical controller forwards the inventory for each logical network to the logical controller for the logical network.

Abstract: Techniques for managing data mobility domains in storage system environments. The techniques employ a multiple master approach, in which each storage system in a storage system domain can function as an owner of the domain. Each domain owner has privileges pertaining to addition of new members to the domain, removal of members from the domain, and modification of domain credentials. When a new storage system is added as a member of the domain, the domain credentials are provided from the domain owner to the new storage system, resulting in the domain credentials being shared among all members of the domain. Domain membership information is also shared among all members of the domain. In this way, the management of storage system domains can be achieved without the need of a domain management server, avoiding a single point of failure or latency and reducing the complexity/cost associated with the domain management server.

Abstract: In an approach, a database management system is configured in a manner that allows all pluggable databases within a cluster to be treated, from the perspective of a user, as though stored on a single container database, even when the pluggable databases are distributed across a plurality of container databases. When a command is received by a database server that is to be executed on all or a subset of the pluggable databases within the cluster, the database inspects mapping information replicated on all container databases within the cluster by a cluster synchronization server to determine which container databases store pluggable databases implicated by the command. The command is then forwarded to the database servers responsible for the determined container databases for execution. As a result, the commands issued by the user can be agnostic in regard to the actual location of the pluggable databases within the cluster.
