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.

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.

A firmware attempts to allocate memory address resources, such as memory addresses in a PCI I/O and a PCI memory address space, to bus devices in a multi-processor computing system. If an out-of-resource (OOR) condition occurs during allocation of the memory address resources, memory address resources can be re-allocated from stacks that were successfully allocated requested resources to stacks that were not successfully allocated requested resources. Memory address resources can also, or alternately, be re-allocated from sockets that were successfully allocated requested resources to sockets that were not successfully allocated requested resources. If stack-level or socket-level readjustment of the memory address resource allocation fails, a base memory address of a configuration memory address space can be lowered, and the allocation can be retried. A pre-defined memory address resource allocation table can also be utilized to allocate the memory address resources following failure of the stack-level and socket-level allocation readjustment.

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.
