Abstract

A method and apparatus are provided for configuring a network switch. Method and apparatus may include, in some embodiments, an application software that may be executing on an application subsystem coupled to a system control subsystem. The application software may, in some embodiments, communicate configuration or other information to the system control subsystem, which may then be utilized to configure the network switch. Additionally, data may be transferred to the application software from the system control subsystem or other subsystem relating to configuration information, fault information, or other data.

Claims

1. A method for configuring a storage network switch having a switch fabric subsystem, an input-output subsystem coupled to said switch fabric subsystem, an application subsystem coupled to said switch fabric subsystem, and a system control subsystem coupled to said switch fabric subsystem, said input-output subsystem and said application subsystem, the method comprising:

a) receiving a command from an application subsystem over a communications port;

b) based on the received command, changing the configuration of the storage network

2. The method of claim 1, further comprising:

in response to the received command, changing the zone configuration of the storage network switch.

3. The method of claim 2, further comprising:

in response to the received command, changing a communications port configuration.

4. A method for transferring data within a storage network switch having an input-output subsystem, an application subsystem coupled to said input-output subsystem, and a system control subsystem coupled to said input-output subsystem and said application subsystem, the method comprising:

a) an application subsystem executing a program;

b) the program transmitting data to a system controller through a communications port;

c) the system controller acknowledging receipt of the data from the program; and

d) the system controller initiating a response to the data.

5. The method of claim 4, further comprising:

determining if a first communications port provides an active and functional linked to the system controller; and

if the first communications port is not linked to the system controller, transmitting the data to the system controller through a second communications port.

6. The method of claim 5, further comprising:

transmitting data that includes a command to the system controller; and

the system controller initiating a response to the transmitted command.

7. A method of claim 6, further comprising:

the system controller changing a zone configuration of the storage network in response to the transmitted command.

8. The method of claim 6, further comprising:

the system controller changing a communications port configuration in response to the transmitted command.

9. The method of claim 6, further comprising:

the system controller changing a notification process in response to the transmitted command.

10. The method of claim 6, further comprising:

the system controller transmitting data to the application subsystem indicating a configuration parameter of the storage network.

11. The method of claim 6, further comprising:

the system controller transmitting data to the application subsystem indicating the status of the storage network or a change in the status or configuration of the storage network.

12. The method of claim 10, further comprising:

the system controller transmitting data including zone information to the application subsystem.

13. The method of claim 10, further comprising:

the system controller transmitting data including a communication port configuration to the application subsystem.

14. A method of claim 11 further comprising:

the system controller transmitting data including fault information to the application subsystem.

15. A system comprising:

a network switch, having a configuration, including;

a switch fabric coupled to an applications subsystem; and

a system controller coupled to the switch fabric and the applications subsystem;

the applications subsystem operative to transmit to the system controller a command; and

the system controller operative to change the configuration of the storage network.

16. The system of claim 15, further comprising the system controller being operative to change the zone configuration of the storage network switch.

17. The system of claim 15, further comprising the system controller being operative to change a communications port assignment.

18. The system of claim 15 further comprising the application subsystem transmitting data to the system controller through a communications port.

19. The system of claim 15, further comprising the application subsystem transmitting data to the system controller through a serial data communications port.

20. The system of claim 15, further comprising the system controller transmitting configuration data to the applications subsystem.

21. The system of claim 15, further comprising the system controller transmitting fault data to the applications subsystem.

22. The system of claim 15, further comprising the system controller transmitting network configuration change data to the applications subsystem.
