Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
Fig. 1 is the schematic flow sheet that transmits the method embodiment of data in fiber optic network provided by the invention.Method embodiment shown in Figure 1 comprises:
Method embodiment provided by the invention, by making corresponding two transmit pories of a WWN Port, and the optical-fibre channel that each transmit port is corresponding different, when making an optical-fibre channel of this WWN Port correspondence break down, can adopt other optical-fibre channels of this WWN Port correspondence to continue transmission, realize the automatic switchover of transfer of data, improved reliability of data transmission.
Below method embodiment provided by the invention is described further:
Fig. 2 is the schematic flow sheet that transmits the method application example of data in fiber optic network provided by the invention.Method application example shown in Figure 2 comprises:
In this step, transmit port can have following combination: physical port, logic port and both combinations, wherein logic port can adopt NPIV (N PortID Virtualization) technology to finish by the virtual generation of physical port.Wherein the physical port with this locality is virtualized at least two logic ports, and wherein this logic port has the transfer function of described physical port, and the logic port that obtains is configured to new transmit port respectively.For example, a physical port be transmit port A, can adopt NPIV that this physical port is virtualized into two logic ports, be called transmit port B and transmit port C, be interpreted as two transmit pories this moment, i.e. transmit port B and C, and wherein transmit port A does not exist.
In this step, at least two of selection ports can be by following several modes of forming:
Mode 1: at least two ports of selection all are physical ports;
Mode 2: at least two port sections of selection are physical ports, and part is a logic port;
Mode 3: at least two ports of selection all are logic ports, but obtain by different physical ports is virtual;
Mode 4: at least two ports of selection all are logic ports, and obtain by identical physical port is virtual.
In this step, by the operation of this step, at least two optical-fibre channels that made same WWN Port information correspondence.
Whether employed optical-fibre channel breaks down in step 205, the detection step 204;
If break down, then execution in step 205; Otherwise, continue to carry out this step.
In this step, finish the continuation transmission of data by the switching of optical-fibre channel.Below to selecting four kinds of modes effect in this step of port to compare in the step 202:
At least two ports selecting in the mode 1 all are physical ports;
Because have only one to be in user mode in the selecteed physical port, other need be closed.In actual applications, the physical port that has part is a closed condition, makes that the utilization rate of physical port is very low.
Mode 2: at least two port sections of selection are physical ports, and part is a logic port;
Because same physical port is that the user mode of a plurality of logic ports is separate, promptly allowing one of two logic port on the same physical port is closed condition, and another is to use state.So improved the actual physical port utilization than mode one, can provide service for more different WWN Port.
Mode 3: at least two ports of selection all are logic ports, but obtain by different physical ports is virtual;
Compare with mode 2, the WWN Port that three of modes can be served is more, but owing to be not to obtain by same physical port is virtual, so when switching optical-fibre channel, need switch to the physical port of another entity from the physical port of an entity, consume the regular hour.
Mode 4: at least two ports of selection all are logic ports, and obtain by identical physical port is virtual.
Compare with mode 3, when identical with logic port number in the mode three, mode 4 is identical with the WWN Port that mode three is served, and because virtual the obtaining of the same physical port of selecteed port, so when switching optical-fibre channel, need not to switch to from the physical port of an entity physical port of another entity, saved the time of switching, switch speed is faster.
This shows that the optimum way of above-mentioned four kinds of modes is a mode 4.
The method that the embodiment of the invention provides, by making corresponding two transmit pories of a WWN Port, and the optical-fibre channel that each transmit port is corresponding different, when making an optical-fibre channel of this WWN Port correspondence break down, can adopt other optical-fibre channels of this WWN Port correspondence to continue transmission, realize the automatic switchover of transfer of data, improved reliability of data transmission.
