Remote configuration of multi-mode DIMMs through a baseboard management controller
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:
receiving, at a baseboard management controller (BMC) of a computing device, a hypertext transfer protocol (HTTP) request from a management client to perform a command on a multi-mode dual in-line memory module (DIMM);
determining, by way of the BMC, if the HTTP request is valid; and
if the HTTP request is valid, transmitting the command from the BMC to the multi-mode DIMM via a system management bus (SMBUS).
2. The computer-implemented method of claim 1 , wherein validating the request comprises determining if the request was submitted by a valid user, determining if a DIMM number specified in the request corresponds to the multi-mode DIMM, determining if a current security state of the multi-mode DIMM enables performance of the command, or validating parameters set forth in the request.
3. The computer-implemented method of claim 1 , wherein the command comprises a command for securely erasing the multi-mode DIMM.
4. The computer-implemented method of claim 1 , wherein the command comprises a command for unlocking the multi-mode DIMM.
5. The computer-implemented method of claim 1 , wherein the command comprises a command for configuring a data policy associated with the multi-mode DIMM.
6. The computer-implemented method of claim 1 , wherein the command comprises a command for canceling a previously-issued command to the multi-mode DIMM.
7. The computer-implemented method of claim 1 , wherein the command comprises a command for setting or disabling a passphrase associated with the multi-mode DIMM.
8. The computer-implemented method of claim 1 , wherein the command comprises a command for locking state changes until a next reboot of the computing device.
9. 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:
receive, at a baseboard management controller (BMC) of the computing system, a hypertext transfer protocol (HTTP) request from a management client to perform a command on a multi-mode dual in-line memory module (DIMM);
determining, by way of the BMC, if the HTTP request is valid; and
if the HTTP request is valid, transmitting the command from the BMC to the multi-mode DIMM via a system management bus (SMBUS).
10. The non-transitory computer-readable storage medium of claim 9 , wherein validating the request comprises determining if the request was submitted by a valid user, determining if a DIMM number specified in the request corresponds to the multi-mode DIMM, determining if a current security state of the multi-mode DIMM enables performance of the command, or validating parameters set forth in the request.
11. The non-transitory computer-readable storage medium of claim 9 , wherein the command comprises a command for securely erasing the multi-mode DIMM.
12. The non-transitory computer-readable storage medium of claim 9 , wherein the command comprises a command for unlocking the multi-mode DIMM.
13. The non-transitory computer-readable storage medium of claim 9 , wherein the command comprises a command for configuring a data policy associated with the multi-mode DIMM.
14. The non-transitory computer-readable storage medium of claim 9 , wherein the command comprises a command for canceling a previously-issued command to the multi-mode DIMM.
15. The non-transitory computer-readable storage medium of claim 9 , wherein the command comprises a command for setting or disabling a passphrase associated with the multi-mode DIMM.
16. A computing system, comprising:
one or more processors;
a baseboard management controller (BMC);
a multi-mode dual in-line memory module (DIMM) supporting a volatile memory mode and a persistent memory mode, the multi-mode DIMM communicatively coupled to the BMC by way of a system management bus (SMBUS); and
at least one non-transitory computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by the one or more processors, cause the computing system to:
receive, at the BMC of the computing system, a hypertext transfer protocol (HTTP) request from a management client to perform a command on the multi-mode DIMM;
determine, by way of the BMC, if the HTTP request is valid; and
if the HTTP request is valid, transmitting the command from the BMC to the multi-mode DIMM via the SMBUS.
17. The computing system of claim 16 , wherein the command comprises a command for configuring a data policy associated with the multi-mode DIMM.
18. The computing system of claim 16 , wherein validating the request comprises determining if the request was submitted by a valid user, determining if a DIMM number specified in the request corresponds to the multi-mode DIMM, determining if a current security state of the multi-mode DIMM enables performance of the command, or validating parameters set forth in the request.
19. The computing system of claim 16 , wherein the command comprises a command for securely erasing the multi-mode DIMM.
20. The computing system of claim 16 , wherein the command comprises a command for unlocking the multi-mode DIMM.
21. The computing system of claim 16 , wherein the command comprises a command for canceling a previously-issued command to the multi-mode DIMM.
