Abstract

Aspects of the present invention include an NPG system that can stop the CNA from requesting a login if the system has reached the ACL login limit. In embodiments of the present invention, the number of available logins can be dynamically calculated and sent to the CNA.

Claims (27)

1. An information handling system in a Node Port Identifier Virtualization Proxy Gateway (NPG) environment, comprising:

a converged network adapter, configurable to receive information pertaining to a number of available logins in the NPG environment;

an input output aggregator (IOA/NPG) switch coupled to the converged network adapter, configurable to determine and to communicate the number of available logins to the converged network adaptor; and

a fibre channel switch, coupled to the input output aggregator (IOA/NPG), to get the FC address for the fibre channel traffic.

2. The information handling system of claim 1 wherein the IOA is a NPIV Proxy Gateway FCoE switch.

3. The information handling system of claim 1 wherein the number of available logins is determined based on a limit of logins available.

4. The information handling system of claim 1 wherein the number of available logins is determined dynamically based on an availability of address space.

5. The information handling system of claim 1 wherein the IOA/NPG switch sets a particular bit to zero to indicate that there are no available logins.

6. The information handling system of claim 1 wherein the IOA/NPG switch communicates that the login limit is reached.

7. The information handling system of claim 1 wherein the converged network adaptor receives information when a login becomes available.

8. A method for logging into a system with multiple allowed logins, the method preformed in a Node Port Identifier Virtualization Proxy Gateway (NPG) environment, the method comprising:

indicating that multiple logins are supported;

setting a particular bit to one to indicate that multiple logins are supported;

calculating a number of supported logins; and

sending the number of supported logins to a converged network adaptor.

9. The method of claim 8 wherein the calculating is done dynamically to determine the number of available logins.

10. The method of claim 8 wherein the method is done in an IOA/NPG FCoE device.

11. The method of claim 8 wherein the calculating is done statically based on a number of permitted logins.

12. The method of claim 8 further comprising recalculating the number of available logins in the event that a logout occurs.

13. The method of claim 8 further comprising notifying the converged network adaptor when a logout occurs.

14. An IOA/NPG FCoE switch used in a Node Port Identifier Virtualization Proxy Gateway (NPG) environment, the switch comprising:

a central processing unit configured to calculate a number of available logins;

a memory configured to store the results of the calculations; and

a IOA/NPG FCoE switch configured to send the number of available logins for receipt by a converged network adaptor.

15. The IOA/NPG FCoE switch of claim 14 wherein the calculation of the number of available logins is done based on the number of permitted logins.

16. The IOA/NPG FCoE switch of claim 14 wherein the calculation of the number of available logins is done dynamically to determine the number of logins available.

17. The IOA/NPG FCoE switch of claim 14 wherein the send module further sends information pertaining to logouts.
