Abstract

An information handling system includes a management interface that may detect a configuration change request for the flash dual in-line memory modules, and may determine whether the configuration change request is a hardware configuration change or a software configuration change. In response to the configuration change request being the software configuration change the management interface may re-configure flash dual in-line memory modules based on a first profile identified by the configuration change request without resetting the information handling system, update metadata for the flash dual in-line memory modules based on the first profile without resetting the information handling system, and update a dual in-line memory module firmware interface table for the flash dual in-line memory modules based on the first profile without resetting the information handling system.

Claims

1. An information handling system comprising:

a plurality of flash dual in-line memory modules;

a central processing unit to communicate with the flash dual in-line memory modules; and

a management interface to detect a configuration change request for the flash dual in-line memory modules, to determine whether the configuration change request is a hardware configuration change or a software configuration change, and in response to the configuration change request being the software configuration change the management interface to;

re-configure the flash dual in-line memory modules based on a first profile identified by the configuration change request without resetting the information handling system, update metadata for the flash dual in-line memory modules based on the first profile without resetting the information handling system; and

update a dual in-line memory module firmware interface table for the flash dual in-line memory modules based on the first profile without resetting the information handling system.

2. The information handling system of claim 1, wherein the flash dual in-line memory modules are re-configured by a flash dual in-line memory module runtime service being invoked based on the first profile.

3. The information handling system of claim 1, wherein the management interface is further to update the flash dual in-line memory modules via a firmware mailbox interface.

4. The information handling system of claim 1, wherein the first profile of the configuration change request is selected from a lookup table within a memory of the information handling system.

5. The information handling system of claim 1, in response to the configuration change request being the hardware configuration change the management interface to:

re-configure the flash dual in-line memory modules based on a platform capability of a second profile identified by the configuration change request.

6. The information handling system of claim 5, wherein the flash dual in-line memory modules are re-configured without resetting the information handling system in response to a change in the second profile being supported by the platform capability.

7. The information handling system of claim 5, wherein the flash dual in-line memory modules are re-configured by a flash dual in-line memory module runtime service being invoked based on a platform capability of the second profile.

8. A method comprising:

detecting, by a management interface, a configuration change request for a plurality of flash dual in-line memory modules of an information handling system;

determining whether the configuration change request is a hardware configuration change or a software configuration change; and

in response to the configuration change request being the software configuration change;

re-configuring the flash dual in-line memory modules based on a first profile identified by the configuration change request without resetting the information handling system;

updating metadata for the flash dual in-line memory modules based on the first profile without resetting the information handling system; and

updating a dual in-line memory module firmware interface table for the flash dual in-line memory modules based on the first profile without resetting the information handling system.

9. The method of claim 8, wherein re-configuring the flash dual in-line memory modules includes invoking a flash dual in-line memory module runtime service based on the first profile.

10. The method of claim 8, further comprising:

updating the flash dual in-line memory modules via a firmware mailbox interface.

11. The method of claim 8, wherein the first profile of the configuration change request is selected from a lookup table within a memory of the information handling system.

12. The method of claim 8, wherein in response to the configuration change request being the hardware configuration change:

re-configuring the flash dual in-line memory modules based on a platform capability of a second profile identified by the configuration change request.

13. The method of claim 12, wherein the flash dual in-line memory modules are re-configured without resetting the information handling system in response to a change in the second profile being supported by the platform capability.

14. The method of claim 12, wherein the flash dual in-line memory modules are re-configured by a flash dual in-line memory module runtime service being invoked based on a platform capability of the second profile.

15. A method comprising:

configuring a plurality of flash dual in-line memory modules of an information handling system according to a first configuration goal;

detecting, by a management interface, a configuration change request for the flash dual in-line memory modules;

determining whether the configuration change request is a hardware configuration change or a software configuration change;

in response to the configuration change request being the software configuration change;

re-configuring the flash dual in-line memory modules based on a first profile identified by the configuration change request without resetting the information handling system;

updating metadata for the flash dual in-line memory modules based on the first profile without resetting the information handling system; and

updating a dual in-line memory module firmware interface table for the flash dual in-line memory modules based on the first profile without resetting the information handling system; and

in response to the configuration change request being the hardware configuration change;

re-configuring the flash dual in-line memory modules based on a platform capability of a second profile identified by the configuration change request.

16. The method of claim 15, wherein re-configuring the flash dual in-line memory modules based on the first profile comprises:

invoking a flash dual in-line memory module runtime service based on the first profile.

17. The method of claim 15, wherein in response to the configuration change request being the software change, the method further comprises:

updating the flash dual in-line memory modules via a firmware mailbox interface.

18. The method of claim 15, wherein the first profile of the configuration change request is selected from a lookup table within a memory of the information handling system.

19. The method of claim 15, wherein the flash dual in-line memory modules are re-configured without resetting the information handling system in response to a change in the second profile being supported by the platform capability.

20. The method of claim 15, wherein the flash dual in-line memory modules are re-configured by a flash dual in-line memory module runtime service being invoked based on a platform capability of the second profile.
