Problems solved by technology

[0009] However, since the FCoE and IP protocols both run on the Ethernet interface, although the above operation can re-negotiate the virtual logical link between the ENode and the FCoE switch, it will also interrupt the operation of the IP service.
[0010] It can be seen that the method of controlling the renegotiation of the virtual logical link in the prior art will affect the normal operation of the IP service in the system

Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0045]In this embodiment, both the FCoE switch and the ENode realize the restart of the virtual logical link by restarting the logical interfaces, that is, the VN interface and the VFC interface. In this way, there is no need to restart the Ethernet interface, so that the restart of the virtual logical link IP services will not be interrupted.

[0046] In addition, for the negotiation and restart of the virtual logical link, in this embodiment, various existing proprietary protocols such as DCBX (Data Center Bridging Capability Exchange Protocol) can be used to realize, and the FIP protocol can also be used to realize.

[0047] However, compared with the FIP protocol, using a private protocol will bring the following problems:

[0048] Take the DCBX pr...

Abstract

The invention discloses a link negotiation control method and a Fibre Channel over Ethernet (FCoE) integration system. In the invention, the FCoE switch and the Ethernet node (ENode) can realize to restart the virtual logic link road by restarting the logic interface without the restart of the Ethernet interface, thus the restart of the virtual logic link road can not break off the service. Moreover, in the invention, the FCoE initialized protocol (FIP)message is used for realizing the negotiation and restart of the virtual logic link road, the problems of increased facility cost, slow response speed and the like caused by using private protocol are avoided.

Description

technical field [0001] The invention relates to the link negotiation technology of Fiber Channel Carrying Ethernet Protocol (FCoE), in particular to a link negotiation control method and an FCoE protocol integration system. Background technique [0002] With the continuous development of Internet applications, the network server needs to store more and more information and data, which in turn leads to the continuous increase of the storage capacity required by the network server. When the internal storage capacity of the web server cannot meet the demand for information growth, it is necessary to "externalize" the storage of the web server. [0003] In order to solve this problem, a storage area network (Storage Area Networks, SAN) has been proposed in the prior art, and the SAN provides a dedicated external storage environment for the network server, making full use of new storage hardware technology and network technology to meet the needs of large-capacity Requirements f...
