News editors obtained the following quote from the background information supplied by the inventors: "The present invention relates in general to gateway devices, and more particularly, to gateway devices for use with Fibre Channel and Fibre Channel over Ethernet devices.
"Fibre Channel is a high reliability, high speed network technology that is often used in storage networking, particularly in storage area network (SAN) environments. Many data centers use Fibre Channel (FC) for storage networking, and, in conjunction, use Ethernet for TCP/IP networks. As a result, the data center has two separate networks to maintain. FCoE is a network protocol that encapsulates Fibre Channel frames in Ethernet frames in order to allow Fibre Channel to be used over an Ethernet infrastructure. FCoE thus allows storage traffic generated according to the FC protocol to share infrastructure with network traffic generated according to Ethernet protocols such as TCP/IP."
As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventor's summary information for this patent application: "An FCoE fabric typically is built with switches and adaptors that support various FC and FCoE protocols. For example, FCoE deployments include translation devices that operate in either full FCoE switch mode (known as Fibre Channel Forwarders (FCF)) or in N_Port virtualization or aggregation mode (AG). FCFs provide full Fibre Channel services (e.g., address assignment, name server, zoning, etc.) to the FCoE fabric and converts FCoE to FC and vice versa. A FCoE switch operating in virtualization or aggregation mode allows a converged network adapter (CNA) to connect over Ethernet to a Fibre Channel SAN as if it were a native FC port. However, solutions are needed for connecting legacy Fibre Channel devices to FCoE SANs or Lossless Ethernet networks.
"In this regard, innovative devices, systems, and methods are provided that seamlessly connect legacy Fibre Channel devices to FCoE devices and/or networks. In one embodiment, by way of example only, a gateway device for use between a Fibre Channel over Ethernet (FCoE) network and a Fibre Channel (FC) storage area network (SAN) device includes a controller, at least one first native Fibre Channel F_Port in operable communication with the controller and configured to interface with a native Fibre Channel N_
"In another embodiment, by way of example only, a network system includes a Fibre Channel over Ethernet (FCoE) server including at least one first virtual N_Port (VN_Port), a Fibre Channel (FC) storage including at least one first native Fibre Channel N_Port, and a gateway device in operable communication with the FCoE server and the FC storage. The gateway devices includes a controller, at least one first native Fibre Channel F_Port in operable communication with the controller and configured to interface with the at least one first native Fibre Channel N_
"In another embodiment, by way of example only, a method of connecting a native Fibre Channel port to a pure Fibre Channel over Ethernet (FCoE) Storage Area Network (SAN) devices is provided. The method includes providing a gateway device including a controller, at least one first native Fibre Channel F_Port in operable communication with the controller and configured to interface with a native Fibre Channel N_
