  • Patent number: 8730840
    Abstract: In a system comprising a first fabric and a plurality of devices coupled to the fabric by Fiber Channel connections, the devices are logically grouped to form configurations and zones. A configuration includes at least one zone, and each zone includes at least one device as a member of the zone. Communications between the devices is restricted according to the configuration currently in effect. For example, one device may be permitted to communicate with another device only if they are members of a common zone.

  • Patent number: 5748612
    Abstract: A method and apparatus for removing a virtual connection between first and second devices in a communication system that includes at least one switch virtually connecting the first and second devices. An error in the virtual connection can be detected in at least one of the first and second devices and the at least one switch, with the detector transmitting a request to remove the virtual connection. The virtual connection then is removed from the communication system in response to the transmission of the request. The request to remove the virtual circuit may be in the form of an information frame transmitted over the virtual connection, with each system component being removed from the virtual circuit upon its processing of the information frame. Additionally, a method and apparatus for operating the virtual connection between the first and second devices.
