Abstract: Architectures and techniques are described that, in the context of a microservice platform, can provide automated discovery and configuration of message brokers on behalf of resident microservices. As a result, microservices no longer need to be tightly bound to a particular message broker. Hence, significant coding changes for microservices developers can be avoided over the lifetime of a particular microservice.

Abstract: Methods and systems support managed use of a Storage Class Memory (SCM) by one or more applications operating on an IHS (Information Handling System). The operations that are supported by an IHS processor for flushing data from the SCM are determined. Applications are identified that operate using the persistent data storage capabilities of the SCM. The SCM flushing operations invoked by each these applications are monitored. The utilization of the SCM by each of the first plurality of applications is determined based at least in part on the monitored flushing operations by each application. The utilization of the SCM may also be based on calculated metrics of SCM utilization by the respective applications. The applications are classified based their determined SCM utilizations. Based on the classifications of SCM utilization, a subset of the applications may be identified for removal from use of the SCM.

Abstract: In accordance with embodiments of the present disclosure, an information handling system may include a processor, a prognostic agent embodied in a program of executable instructions and configured to, when executed, maintain a prognostic data structure setting forth a plurality of parameters regarding a non-volatile memory of the information handling system, and a memory controller configured. The memory controller may be configured to calculate a severity index based on the parameters set forth in the prognostic data structure, the severity index indicative of a likelihood of successfully completing a save operation to the non-volatile memory from a volatile memory in response to a power event of the information handling system and based on the severity index, determine whether or not to perform a save operating in response to a power event of the information handling system.

Abstract: A management controller includes a microcontroller and a managed system interface for coupling the management controller to a managed system. The managed system includes a central processing unit (CPU) and a system memory comprised of non-volatile dual in-line memory module (NVDIMM). The management controller is coupled to a management network by an out-of-band interface. The management controller provides a remote management user interface that includes a selectable out-of-band NVDIMM save element. The management controller may establish a connection with an operating system agent and control the agent to perform operations including accessing a memory map to identify an NVDIMM, configuring the NVDIMM in an asynchronous DRAM refresh mode, and triggering an NVDIMM save before toggling CPU reset.

Abstract: The described technology is generally directed towards a message broker resource monitoring service that obtains message broker resource parameter data of a resource, based on communications of a message broker. Based on the resource parameter data and historical data, message broker resource monitoring service obtains a predicted message delivery time value, which can be in association with confidence. If the predicted message delivery time value satisfies a resource deletion criterion, e.g., the predicted message delivery time value, with sufficient confidence, exceeds a threshold value, the message broker resource monitoring service triggers an action to delete the resource. To obtain the predicted value, a regression such as symmetric conformal quantile regression can be applied to the parameter data, e.g., to obtain a predicted message delivery time/latency value.

Abstract: A method, information handling system (IHS) and sub-system for enabling booting of the IHS using different operating system configurations. The method includes retrieving, via a processor, a unified extensible firmware interface (UEFI) image from a storage device and initializing at least one UEFI runtime service. The processor determines if a memory map corresponding to the UEFI runtime service defines multiple memory descriptors. In response to determining that the memory map defines multiple memory descriptors, a common memory descriptor is identified. The UEFI runtime service and the corresponding memory map are aligned to the common memory descriptor. The aligned UEFI runtime service and the corresponding memory map are copied to a system memory of the IHS. The operating system is booted, wherein the aligned UEFI runtime service and the corresponding memory map are compatible with operating systems that support single runtime memory descriptors.
