摘要： A Fibre Channel over Ethernet (FCoE) network can be inexpensively extended by additional switches (220x) that do not have a full FCoE functionality, e.g. do not have full E-port functionality. The additional switches may or may not have unique Domain IDs. A virtual switch fabric can be extended by such additional switches.

摘要： An automatic fabric provisioning system includes first uplink switch device(s) associated with a first fabric, and second uplink switch device(s) associated with a second fabric. A gateway device is coupled to each of the first and second uplink switch device(s), and transmits a respective fabric login communication to each of the first uplink switch device(s) via at least one first uplink, and to each of the second uplink switch device(s) via at least one second uplink. When the gateway device receives respective first fabric login accept communication(s) from each of the uplink switch device(s) via the at least one uplink to that uplink switch device that identifies the fabric associated with that uplink switch device, it automatically associates each at least one first uplink with the first fabric, and each at least one second uplink with the second fabric.

摘要： An ALUA path selection system includes a networking device in a networking fabric that couples a host device to a storage subsystem. The networking device receives a host device communication generated by the host device and retrieves a host device hop count that identifies a number of hops between the host device and the networking device. The networking device also receives a storage subsystem communication generated by the storage subsystem and retrieves a storage subsystem hop count that identifies a number of hops between the storage subsystem and the networking device. When the networking device receives a hop count request from the host device, it transmits the host device hop count and/or the storage subsystem hop count to the host device, and the host device uses the host device hop count and/or the storage subsystem hop count to select an active-optimized path to a LUN included in the storage subsystem.

摘要： A Fibre Channel Forwarder (FCF) routing system includes an FCF device that is coupled to a FC networking device through a first FCF device port, an initiator device through a second FCF device port; and a target device through a third FCF device port. The FCF device receives, at the second FCF device port, traffic that originates from the first initiator device and that is addressed to the first target device. The FCF device determines, using an FCF device association table that identifies zones provided by the FC networking device, that the target device is associated with the initiator device. The FCF device then routes, in response to determining the target device is associated with the initiator device, the traffic through the third FCF device port to the target device without forwarding the traffic through the first FCF device port to the FC networking device.

摘要： A Fibre Channel Forwarder (FCF) port auto-configuration system includes a Fibre Channel (FC) networking device and an FCF device that includes a plurality of ports. The FCF devices configures, in response to a link being established on a first port of the plurality of ports, the first port as a first type port that indicates that the first port is connected to a second type port on the FC networking device. The FCF device provides a first fabric login through the first type port. In response to the FCF device not receiving an acceptance of the first fabric login after a first predetermined time threshold, the FCF device configures the first port as the second type port.

摘要： A Fibre Channel Forwarder (FCF) load balancing system includes a Fibre Channel Forwarder (FCF) device that is coupled to a Fibre Channel (FC) networking device and the first server device. The FCF device groups a first link between the FC networking device and the FCF device with a second link between the FC networking device and the FCF device in response to receiving both a first fabric login accept on the first link that includes a first Worldwide Name (WWN) and a second fabric login accept on the second link that includes the first WWN. The FCF device provides at least a portion of traffic, received from the first server device that is logged in through the first link, through the second link.

摘要： A registered state change notification system includes a switch device that is coupled to a plurality of end devices to provide a fabric. An application executing on the switch device detects a change that is associated with a zone in the fabric that includes a plurality of end devices and, in response, generates a multicast Registered State Change Notification (RSCN) that includes a Zone Fiber Channel Identifier (FCID) that is associated with the zone. Subsequently and without the use of the application, multicast hardware included in the switch device sends the multicast RSCN including the Zone FCID to at least a subset of the plurality of end devices.

摘要： A secure FC NVMe fabric communications system includes a host device having host WWPNs associated with each of its host NQNs, an NVMe target device having a target WWPNs associated with each of its target NQNs, and FC networking device(s) that couple the host device to the NVMe target device. The FC networking device(s) perform, for each host WWPN associated with the host NQNs, host login operations that register the host NQN for that host WWPN as an NVMe host, and perform, for each target WWPN associated with the target NQNs, target login operations that register the target NQN associated with that target WWPN as an NVMe target. The FC networking device(s) then provide, to the host for each host NQN, target NQN details for target NQN(s) zoned for communication with that host NQN to allow respective communication session(s) to be established between the host NQN and those target NQN(s).

摘要： A Fibre Channel host onboarding system includes a Fibre Channel communication subsystem coupled to a host system in a modular computing system. The host system includes a Baseboard Management Controller (BMC) device that retrieves and transmits host system onboarding information associated with the host system. The host system also includes a Host Bus Adapter (HBA) device that is coupled to the BMC device, and that receives the host system onboarding information from the BMC device and, in response, transmits a host system discovery communication that includes the host system onboarding information to the Fibre Channel communication subsystem. When the HBA device determines that a host system discovery acknowledgement communication has been received from the Fibre Channel communication subsystem, it performs Fibre Channel fabric login operations with the Fibre Channel communication system that configure the host system for Fibre Channel communications via the Fibre Channel communication subsystem.
