Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0039] Set up a switch in the SAN to communicate with the network management system. The switch is added to all the VSANs in the SAN, and the VSANs are isolated in the switch. Therefore, even if the switch exists in multiple VSANs, the independence of services in each VSAN can still be maintained, thereby better maintaining network security. Wherein, the switch configured above may be a switch selected in the SAN, or may be a switch added in the SAN. In order to distinguish it from other switches in each VSAN, we call the switches in all the VSANs added to the SAN a seed switch in specific embodiments.

Abstract

The invention discloses a storage area network (SAN) discovery method. A switchboard communicated with a network administration system (NMS) is arranged in an SAN, the switchboard is added to all the VSANs (virtual storage area network) in the SAN and records the VSAN range, and all the added VSANs are isolated by the switchboard inside the switchboard. The method comprises the following steps: after receiving a SAN discovery request sent by the NMS, the switchboard determines the VSANs to which automatic discovery messages need to be published according to the VSAN range requested by the NMS and the VSAN range recorded by the switchboard, and then respectively publishes the automatic discovery messages to the determined VSANs; and after receiving the reported VSAN information and the information of network elements in the VSANs, the switchboard responds to the NMS. The invention also provides the switchboard based on a conception same as that of the method. By adopting the SAN discovery method and the switchboard, SAN discovery can be realized by a simple method on the premise of ensuring network security.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a storage area network (SAN) discovery method and a switch. Background technique [0002] In order to enable the network management system to manage the SAN network, the Mesh Channel (FC) network provides a network discovery mechanism, that is, the FC switches in the FC network transmit network discovery packets to each other, and the composition and topology of the network are in the Spreading in the network, the network management can obtain the composition and topology of the network to which the switch belongs through any FC switch device in the network, and then describe the structure of the network and perform various management operations. [0003] In an FC storage network, a SAN network is usually divided into multiple virtual storage area networks (VSANs) to ensure network security. Packets can communicate within a VSAN, but cannot communicate between VSANs. Gene...
