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.

Remote configuration of multi-mode DIMMs through firmware

Technologies are described for verifying the integrity of data transmitted between a firmware and a baseboard management controller ('BMC'). During a first verification phase, a data integrity tool compares system inventory data provided by firmware protocols to a system inventory module to system inventory data in a device instance format. During a second verification phase, the data integrity tool verifies operation of a firmware conversion module by comparing the system inventory data in the device instance format to the system inventory data in a JavaScript Object Notation ('JSON') format. During a third verification phase, the data integrity tool retrieves the system inventory data from a management server and compares the system inventory data retrieved from the management server to the system inventory data previously transmitted to the management server. Identified discrepancies can be utilized to modify the system inventory module, the firmware conversion module, or the management server.

Simultaneous initiation of multiple commands for configuring multi-mode DIMMS using a BMC

In an aspect of the disclosure, a method, a computer-readable medium, and a computer system are provided. The computer system includes an initialization component of a host. The initialization component obtains health data indicating that at least one hardware component of the host is in one of one or more predetermined health conditions when executed in a system management mode of the host. The initialization component then sends, to a service processor of the host, a message in accordance with a management protocol. The message includes the health data.

Techniques of monitoring and updating system component health status

Technologies are disclosed for identifying and remediating correctable hardware errors. A firmware can detect a system management interrupt ('SMI') generated by a hardware device responsive to the occurrence of a correctable error. Once the firmware has identified the device that generated the SMI, the firmware can determine whether an earliest recorded error generated by the identified device is longer ago than a threshold amount of time. If the earliest recorded error generated by the device is not longer ago than the threshold amount of time, the firmware can increment an error count for the device. The firmware can also determine whether the error count for the device exceeds a threshold. If the error count for the device exceeds the threshold, the firmware can generate an error notification for the device. The firmware can also implement a remedial action policy for the device.

Identifying an remediating correctable hardware errors

In an aspect of the disclosure, a method, a computer-readable medium, and a computer system are provided. The computer system includes an initialization component of a host. The initialization component determines presence or absence of a plurality of hardware components of the host. The initialization component further generates a first series of indicators indicating the determined presence or absence of the plurality of hardware components. The initialization component sends, to a service processor of the host, a message in accordance with a management protocol, the message including the first series of indicators.
