Abstract
The embodiment of the invention discloses method, the network switch and the network system of a kind of network switch interaction, when the first server of first network interchanger service needs to access the second server of second network switch service, the first network interchanger is the first server configuration agent functionality, and the first network interchanger obtains the name server Name Server information of second network switch；The first network interchanger merges the Name Server information of the SAN network switch where the Name Server information of second network switch and the first network interchanger, and the Name Server information after merging is sent to the first server, so as to realize that the first server can be while the server of the network switch service where the server or difference SAN that the network switch where accessing same SAN is serviced.
Description
Technical field
The invention belongs to method, the network switch and the network of the communications field, more particularly to a kind of interaction of network switch
System.
Background technology
Optical-fibre channel (English：Fibre Channel, abbreviation：FC) storage network is called fibre channel sanses
(English：Fibre Channel storage area network, abbreviation：FC SAN), by node (Node) and optical-fibre channel
Network (English：Fibre Channel fabric) composition, the Node is with host bus adaptor (English：host
Bus adapter, abbreviation：HBA main frame (host) or storage device).Node needs the net to FC Fabric in initialization
Network interchanger (English：Network switch) registration, it is (English that FC Fabric can distribute a N-port mark：N Port
Identifier, abbreviation：N_Port ID) give Node, the N_Port ID to be also known as fibre channel address (English：Fibre
Channel identifier, abbreviation：FCID).
Common N-port virtualization (English：N__Port virtualization, abbreviation：NPV) the network of pattern
Switch is equivalent to the proxy server (English between hosts in FC SAN and standard network switch：proxy
Server), the network switch of the standard possess the ability of processing FC agreements and forwarding FC messages, NPV patterns
Network switch do not possess the ability of processing FC agreements, and do not possess forwarding FC message abilities so that institute under NPV patterns
Some hosts flow will be sent on the standard network switch and exchange, and the network switch of NPV patterns are not
Network service (English can be provided：Fabric service), the network service includes distribution FCID, domain name service, FC routes
Forwarding etc.；The network switch of NPV patterns can not provide the E ports interacted with other standards network switch, because
The network switch of this NPV pattern can not constitute the SAN network of oneself.
Another common technology is the NPV patterns based on port granularity.NPV patterns based on port granularity be with
Network switch ports are that base unit starts NPV patterns, and a part of port starts NPV patterns, and a part of port is not opened
Dynamic NPV patterns, network switch are interacted by N-port with the network switch of different manufacturers, the different manufacturers
Refer to the incompatible each producer for causing E ports to dock of the agreement of E ports, and the networkswitch possesses processing FC
The ability and forwarding FC message abilities of agreement, can provide Fabric Service, can support E ports.But the network
The server that switch not only needs to act on behalf of under the network switch domains is noted to the network switch of different manufacturers
Volume, in addition it is also necessary to which the server acted on behalf of under the network switch domains of other producers is registered to the network switch, because
This agreement flow is complicated.
The content of the invention
It is an object of the invention to provide method, the network switch and the network system of a kind of network switch interaction, purport
Solve how to enable same producer network switch domains under server access different manufacturers network
The problem of server under switch domains.
In a first aspect, a kind of method of network switch interaction, methods described includes：

Overseas N-port identifies N_PORT_ID, and storage mapping relation, and the mapping relations are the N_PORT_ID and overseas N_ in domain
N_PORT_ID is that the first network interchanger distributes for the first server in PORT_ID corresponding relation, the domain
N_PORT_ID；Obtain the Name Server information of second network switch；By the Name of second network switch
The Name Server information of the network switch of storage area network is closed where Server information and the first network interchanger
And, the Name Server information after being merged；Name Server information after merging is sent to first server；
Wherein, the first server and first network interchanger connection, the second server and second network
Interchanger is connected, and the E Port Profiles of the first network interchanger and second network switch are incompatible.
6. network system according to claim 5, it is characterised in that the first network interchanger obtains second net
The Name Server information of network interchanger, including：
The first network interchanger receives the Name Server for the acquisition second server that the first server is sent
The request of information, the acquisition second that the first network interchanger sends the first server according to the mapping relations takes
N_PORT_ID is revised as corresponding with N_PORT_ID in the domain in the domain in the request of the Name Server information of business device
The overseas N_PORT_ID, and sent to second network switch and amended obtain second network switch
The request of Name Server information；
Receive the Name Server information for the second server that the second server is sent.
