Remote configuration of multi-mode DIMMs through firmware
Technologies are described herein for remotely configuring multi-mode dual in-line memory modules (“multi-mode DIMMs”) using a firmware or a baseboard management controller (“BMC”). Technologies are also described for simultaneously initiating multiple commands for configuring multi-mode DIMMs using a BMC and for updating inventory data regarding multi-mode DIMMs stored by a BMC.
1. A computer-implemented method, comprising:
executing a firmware on a central processing unit (CPU) of a computing system, the computing system comprising a baseboard management controller (BMC);
receiving, at the BMC, a request from a management client to perform a command on a multi-mode dual in-line memory module (DIMM), the multi-mode DIMM supporting a volatile memory mode and a persistent memory mode;
responsive to receiving the request at the BMC, storing data identifying the command in a data store;
retrieving, by way of the firmware executing on the CPU of the computing system, the data identifying the command from the data store; and
issuing, by way of the firmware executing on the CPU of the computing system, the command to a firmware of the multi-mode DIMM.
2. The computer-implemented method of claim 1 , wherein the command comprises a request to allocate a capacity of the multi-mode DIMM between the volatile memory mode and the persistent memory mode.
3. The computer-implemented method of claim 1 , wherein the command comprises a command to create a namespace associated with the multi-mode DIMM.
4. The computer-implemented method of claim 1 , wherein the command comprises a command to delete a namespace associated with the multi-mode DIMM.
5. The computer-implemented method of claim 1 , wherein the command comprises a command to delete platform configuration data stored on the multi-mode DIMM.
6. The computer-implemented method of claim 1 , wherein the command comprises a command to perform a diagnostic operation on the multi-mode DIMM.
7. The computer-implemented method of claim 1 , wherein the computing system is rebooted a first time prior to retrieving the data identifying the command from the data store and issuing the command to the firmware of the multi-mode DIMM, and wherein the firmware executing on the CPU of the computing system is further configured to cause the computing system to reboot a second time after issuing the command to the firmware of the multi-mode DIMM.
8. A non-transitory computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by a computing system, cause the computing system to:
execute a firmware on a central processing unit (CPU) of the computing system, the computing system comprising a baseboard management controller (BMC);
receive, at the BMC, a request from a management client to perform a command on a multi-mode dual in-line memory module (DIMM), the multi-mode DIMM supporting a volatile memory mode and a persistent memory mode;
responsive to receiving the request at the BMC, store data identifying the command in a data store;
retrieve, by way of the firmware executing on the CPU of the computing system, the data identifying the command from the data store; and
issue, by way of the firmware executing on the CPU of the computing system, the command to a firmware of the multi-mode DIMM.
9. The non-transitory computer-readable storage medium of claim 8 , wherein the command comprises a request to allocate a capacity of the multi-mode DIMM between the volatile memory mode and the persistent memory mode.
10. The non-transitory computer-readable storage medium of claim 8 , wherein the command comprises a command to create a namespace associated with the multi-mode DIMM.
11. The non-transitory computer-readable storage medium of claim 8 , wherein the command comprises a command to delete a namespace associated with the multi-mode DIMM.
12. The non-transitory computer-readable storage medium of claim 8 , wherein the command comprises a command to delete platform configuration data stored on the multi-mode DIMM.
13. The non-transitory computer-readable storage medium of claim 8 , wherein the command comprises a command to perform a diagnostic operation on the multi-mode DIMM.
14. The non-transitory computer-readable storage medium of claim 8 , wherein the computing device is rebooted a first time prior to retrieving the data identifying the command from the data store and issuing the command to the firmware of the multi-mode DIMM, and wherein the firmware executing on the CPU of the computing system is further configured to cause the computing device to reboot a second time after issuing the command to the firmware of the multi-mode DIMM.
15. A computing system, comprising:
a central processing unit (CPU);
a baseboard management controller (BMC);
a multi-mode dual in-line memory module (DIMM) supporting a volatile memory mode and a persistent memory mode; and
at least one non-transitory computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by the computing system, cause the computing system to:
execute a firmware on the CPU;
receive, at the BMC, a request from a management client to perform a command on the multi-mode DIMM;
responsive to receiving the request at the BMC, store data identifying the command in a data store;
retrieve, by way of a firmware executing on the CPU of the computing system, the data identifying the command from the data store; and
issue, by way of the firmware executing on the CPU of the computing system, the command to a firmware of the multi-mode DIMM.
16. The computing system of claim 15 , wherein the command comprises a request to allocate a capacity of the multi-mode DIMM between the volatile memory mode and the persistent memory mode.
17. The computing system of claim 15 , wherein the command comprises a command to create a namespace associated with the multi-mode DIMM.
18. The computing system of claim 15 , wherein the command comprises a command to delete a namespace associated with the multi-mode DIMM.
19. The computing system of claim 15 , wherein the command comprises a command to delete platform configuration data stored on the multi-mode DIMM.
20. The computing system of claim 15 , wherein the computing system is rebooted a first time prior to retrieving the data identifying the command from the data store and issuing the command to the firmware of the multi-mode DIMM, and wherein the computing system is rebooted a second time after the command is issued to the firmware of the multi-mode DIMM.
