Abstract: In some embodiments, an apparatus includes a management module configured to assign a unique set of identifiers to each network control entity from a set of network control entities. As a result, a network control entity from the set of network control entities can assign an identifier from its unique set of identifiers to a port in response to that network control entity receiving a login request from the port. The set of network control entities is associated with a distributed multi-stage switch. The management module is also configured to store a zone set database associated with the distributed multi-stage switch. The management module is configured to send an instance of an active zone set stored within the zone set database to each network control entity from the set of network control entities such that each network control entity can enforce the active zone set.

Abstract: A system includes multiple edge devices configured to be operatively coupled to a switch fabric. The switch fabric and the multiple edge devices collectively define at least a portion of a core portion of a data center. An edge device from the multiple edge devices is configured to receive a physical address value included in a request from a source peripheral processing device disposed outside of the core portion of the data center. The physical address value represents a destination of a packet queued at the source peripheral processing device. The edge device is configured to send, in response to the request, a tunnel value representing a physical address space including the physical address value to the source peripheral processing device.
