Disclosed systems and methods include a CPU coupled to one or more storage resources including a hybrid storage resource that is user-configurable during boot to allocate some, all, or none of its capacity as a conventional dual in-line memory module (DIMM) and some, all, or none of its capacity as a persistent storage resource. A utilization efficiency index (UEI) of the hybrid storage resource is assessed. The UEI may be determined based on a combination of memory resource utilization, a persistent storage resource utilization, and weighting parameters that reflect a comparative utility or value of memory vs storage resources. A target division between memory and storage resources may then be determined based on the UEI assessment. The hybrid storage resource may then be configured by dividing or allocating a first portion of its capacity to the volatile memory resource and a remaining portion of its capacity to the persistent storage resource.

Optimizing memory to storage capacity division on a DC persistent memory module (DCPMM) in mixed mode

An information handling system may include at least one processor; and a non-transitory memory coupled to the at least one processor. The information handling system may be configured to: execute a plurality of virtual machines having workloads associated therewith; during selected times, apply a plurality of configuration settings relating to the at least one processor while executing the workloads of the plurality of virtual machines; track a plurality of performance metrics relating to the at least one processor during the selected times; and predictively determine a selected one of the plurality of configuration settings that is predicted to improve performance of the workloads.

Configuration optimization with performance prediction

An information handling system may include a persistent memory configured to be secured via a passphrase; a basic input/output system (BIOS); and a management controller configured to provide out-of-band management of the information handling system. The BIOS may be configured to set the passphrase of the persistent memory, encrypt the passphrase via a first key of a first asymmetric key pair, and transmit the encrypted passphrase to the management controller. The management controller may be configured to decrypt the encrypted passphrase via a second key of the first asymmetric key pair, re-encrypt the passphrase via a first key of a second asymmetric key pair, and transmit the re-encrypted passphrase to an external management console via an out-of-band management interface.

Persistent memory passphrase management

A computing device is provided including a motherboard including a control module, a first trusted platform module (TPM), and a second TPM. The control module directs security operations to the first TPM, wherein the control module is operable to detect whether or not the first TPM is damaged, and wherein the control module, in response to detecting that the first TPM is damaged, is operable to direct subsequent security operations to be performed by the second TPM. A computer program product is also provided including non-transitory computer readable storage media embodying program instructions executable by a processor to direct security operations to a first TPM coupled to a motherboard of the computing device, detect whether or not the first TPM is damaged, and, responsive to detecting that the first TPM is damaged, direct subsequent security operations to a second TPM coupled to the motherboard of the computing device.

Computing device having two trusted platform modules

A method includes a unified extensible firmware interface of a compute node identifying an option ROM or an OS boot loader within the compute node, wherein the option ROM or OS boot loader stores a signed image that can be verified using a required digital certificate. The method further includes determining that the unified extensible firmware interface does not store the required digital certificate in a revocation database or in an authorization database. Still further, the method includes automatically identifying the required digital certificate in a database of digital certificates other than the revocation database or the authorization database, and providing the required digital certificate to the authorization database.
