  • Patent number: 8214528
    Abstract: Embodiments of the present invention allow for address scaling of existing addresses in a FC, FCoE, CEE or other type of network. More specifically, subaddresses can be used in conjunction with existing addresses, so that a combination of a subaddress and existing address can identify an addressable entity. Thus, multiple entities can be share a single existing address and be distinguished among each other by way of their respective subaddresses. Some embodiments of the invention allow for use of the inventive subaddressing scheme in conjunction with devices or network elements (e.g., gateways, switches, etc.) that may not be subaddressing aware. Further embodiments allow for the multiple distinct devices to communicate with a single Fiber Channel switching element through a single port by using N_Port_ID Virtualization.

  • Patent number: 7969989
    Abstract: Embodiments of the present invention are directed to a device which may be used for communication through an Ethernet network. The device may comprise two modules. A first module may be based on an existing Fibre Channel arbitrated loop HBA technology. The second module may be configured to provide a virtual Fibre Channel arbitrated loop network for the first module utilizing the Ethernet network. In other words the second module may process communications generated by the first module as well as incoming communications from the Ethernet network in order to make it appear to the first module that it is communicating with an actual Fibre Channel Arbitrated Loop network (whereas it is actually communicating through an Ethernet network). Thus, existing Fibre Channel technology can be used for the first module and the overall design cost of the device can be reduced.

  • Publication number: 20110051733
    Abstract: Disclosed is an improved mechanism for direct communications and frame routing between FCoE devices within an Ethernet network supporting FCoE protocols. In particular, the methods and systems disclosed herein enable direct communications from one FCoE device to another without going through any intermediary such as an FCF (FCoE Forwarder) that is designed to route traffic between FCoE devices according to the current FCoE standards. This is accomplished by registering the Ethernet MAC address of an FCoE device in a name server via certain objects presently used in an FIP fabric login request, e.g., Port_Name or Node_Name, and other standard-specified objects and functionalities without requiring any changes to the existing FCoE and FC standards.

  • Publication number: 20090161692
    Abstract: This is directed to providing Fibre Channel over Ethernet communication. For example a Fibre Channel over Ethernet (FCoE) enabled device (such as a computer) may include a Fibre Channel over Ethernet Adapter (FCoEA). The FCoEA may include an HBA module. The HBA module may be configured to communicate over the Fibre Channel protocol. The FCoE enabled device may process and encapsulate the HBA module's communication in order to send them over an Ethernet network instead. The FCoE enabled device may process communications directed to various Fibre Channel fabric services by utilizing existing Ethernet services, such as an iSNS server. Thus, the FCoE enabled device can emulate a Fibre Channel network for the HBA module using the Ethernet network and one or more Existing Ethernet services/servers.

  • Publication number: 20090164630
    Abstract: Embodiments of the present invention are directed to enforcing zoning at a network adapter of an end point device. Thus, a network adapter can monitor the communications that are sent and/or received by the adapter and discard communications that are prohibited based on the zoning rules applicable to the adapter. In some embodiments, zoning configuration information can be defined and stored at a central entity and sent to the various network adapters. Alternatively, or in addition, each network adapter can also check outgoing communications to ensure that they include a proper source address. More specifically, outgoing communications may be checked to ensure that their source address is the address (or one of the addresses) that are associated with the network adapter. This can be used to detect and/or prevent malfunctions and/or intentional tampering or hacking.
