摘要:
System and computer program product embodiments for fiber channel forwarder fabric login sequence in a fiber channel switch environment, where a Fiber Channel Forwarder (cFCF) is separated from a Fiber Channel over Ethernet (FCoE) data forwarder (FDF), are provided. In one embodiment, by way of example only, at a Fiber Channel Login (FLOGI) to a target device from an initiator device, a node address acceptance notification is held from reaching the initiator device until each of the zoning distributions have been considered to have been completed.

摘要:
An apparatus, system, and method are disclosed for establishing a point-to-point connection using Fibre Channel over Ethernet (FCoE). The point-to-point connection is established as part of the FCoE Initialization Protocol (FIP). A first computing device sends a FIP discovery solicitation to a predefined address such as ALL-FCF-MACs. The first computing device also listens to the local ALL-FCF-MACs address and determines whether or not there are any switches in the fabric connecting the first computing device and the second computing device. If there are no switches, the first computing device sends a second FIP discovery solicitation with a point-to-point indicator. If the first computing device receives a similar FIP discovery solicitation from the second computing device, it sends a FIP discovery advertisement with the point-to-point indicator. The first computing device and second computing device then perform fabric login and establish a point to point connection.

摘要:
A Fibre Channel over Ethernet (FCoE) device obtains knowledge of the configuration of an attached Ethernet fabric during a fabric initialization or login (FLOGI) process. FCoE N_Ports obtain similar information during the port initialization or login (PLOGI) process. The FCoE device may provide network management services to attached FCoE devices. Embodiments include a management module or processor within an FCoE N_Port. The management module or processor receives information associated with an Ethernet fabric from the FCoE N_Ports and provides management services based on the information associated with the Ethernet fabric. The FCoE N_Port communicatively couples to at least one additional FCoE N_Port through the Ethernet fabric. The FCoE N_Ports may be implemented within a disc storage drive, a host bus adapter, and/or an FCoE switch. The capability of an N_Port to obtain this information allows a management module or processor at the N_Port to manage the Ethernet fabric.
摘要:
A method, system, and computer program product for providing direct communications between FCoE endpoint devices within the same fibre channel network zone. A direct fibre channel (DFC) utility provides an FCoE stack with an exclusive ability to define an Ethertype within an ethertype field of an Ethernet packet with “FCoE”. In addition, the DFC utility enables storage of access control lists (ACLs) containing allowed destination addresses and allowed source addresses within the adapter of an FCoE endpoint. Additionally, the DFC utility initiates an exchange of messages with an Ethernet switch to determine a feasibility of establishing direct connections between endpoints. In particular, the DFC utility determines whether the Ethernet switch supports FCoE ACL checking. Further, the DFC utility creates a zone ID for the FCoE endpoint device. The DFC utility allows direct communication between FCoE endpoints within the same fibre zone.

A Fibre Channel over Ethernet (FCoE) device obtains knowledge of the configuration of an attached Ethernet fabric from data fields within a frame header during a fabric initialization or login (FLOGI) process. FCoE N_Ports obtain similar information during the port initialization or login (PLOGI) process. The FCoE device may provide network management services to attached FCoE devices. Embodiments include a management module or processor within an FCoE N_Port. The management module or processor receives a frame having a header and validates and extracts information associated with an Ethernet fabric from the FCoE N_Ports and in order to provide management services based on the information associated with the Ethernet fabric. The FCoE N_Port communicatively couples to at least one additional FCoE N_Port through the Ethernet fabric. The FCoE N_Ports may be implemented within a disc storage drive, a host bus adapter, and/or an FCoE switch.

摘要:
A method for detecting a switch failure and managing switch failover in a Fibre Channel over Ethernet network. The plurality of Fibre Channel over Ethernet switches are connected to an intermediary Ethernet switch and to each other via an Ethernet connection. The intermediary Ethernet switch is different from the plurality of Fibre Channel over Ethernet switches. A plurality of end polls are also connected to the intermediary Ethernet switch. A failure is detected in a first switch in the plurality of Fibre Channel over Ethernet switches. The first switch is associated with a first end port in the plurality of end ports. A failure notification is sent to the first end port using the intermediary Ethernet switch. The failure notification might specify a second switch destination and an identification of the first switch. A fabric login is exchanged between the first end port and the second switch.
