Link negotiation method based on fiber channel aggregate port and device

Abstract

The invention discloses a link negotiation method based on a fiber channel aggregate port and a device. Configuration used for negotiation of the aggregate port is set at the aggregate port in advance in a unified way aiming at all member ports, aggregate port negotiation is only executed once when the first member port is added, and the parameter obtained by the aggregate port negotiation is stored in the aggregate port; while, the stage of aggregate port negotiation is omitted for other member ports which are subsequently added; therefore, all the member ports are unnecessary to execute the whole link negotiation process once, thus improving the efficiency of link negotiation. Furthermore, when the member ports approved by member negotiation are selected, the member port negotiation parameters are unnecessary to be compared with aggregate port negotiation parameters to determine whether the parameters are consistent, thus the same configuration on all the member ports is not needed, and the configuration workload of the member ports is further reduced; meanwhile, the problem of difficult processing caused by inconsistent negotiation parameters does not exist.

Description

technical field [0001] The invention relates to link negotiation technology, in particular to a link negotiation method based on a fiber channel (Fibre Channel, FC) aggregation port and a link negotiation device based on an FC aggregation port. 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-cap...

In this way, the configuration workload of member ports is increased.

[0009] 3) Since the aggregation interface negotiation is carried out after a member interface is selected to join, and the ESC negotiation and VSAN negotiation on the aggregation interface are based on the current member interface and the ELP negotiation and ESC negotiation of the previously selected member interface Therefore, the parameters obtained through ELP negotiation and ESC negotiation on the current member interface are inconsistent with the parameters obtained through ESC negotiation and VSAN negotiation on the aggregation interface, and it is impossible to select which parameter of the selected member interface should be used for ELP negotiation. Negotiation with the ESC makes it difficult to deal with inconsistencies in the negotiation parameters
