Abstract: An apparatus includes physical layer circuitry with lanes to couple the apparatus to endpoint devices. a first input/output (I/O) controller to couple a first processor to the physical layer circuitry, and a second I/O controller to couple a second processor to the physical layer circuitry. The first and second I/O controllers are compatible with a Peripheral Component Interconnect Express (PCIe)-based protocol. The apparatus also includes a flexible input/output adapter (FIA) coupling the first and second I/O controllers to the lanes. The FIA selectively assigns access to each lane of the lanes by either the first or second I/O controller. The apparatus also includes a power management controller (PMC) communicably coupled to the FIA. The PMC causes the FIA to dynamically assign access to at least one of the lanes by the first or second I/O controller without a reboot cycle.

Abstract: Technology for a computing system is described. The computing system can include memory, a controller, and a security management module. The controller can receive a block erase command for erasing data stored in a block of memory. The controller can store information associated with the block erase command in a store, wherein the information includes a block address associated with the data to be erased based on the block erase command. The security management module can read block addresses from the store, update a block erase count array over a defined interval to include block addresses read from the store, compare the block erase count array to a defined threshold, identify block addresses for which the block erase count array is above the defined threshold, and deny subsequent block erase commands for the identified block addresses.

Abstract: Method and apparatus for dynamic Node healing in a Multi-Node environment. A multi-node platform controller hub (MN-PCH) is configured to support multiple nodes through use of dedicated interfaces and components and shared capabilities. Interfaces and components may be configured to be used by respective nodes, or may be configured to support enhanced resiliency as redundant primary and spare interfaces and components. In response to detecting a failing or failing primary interface or component, the MN-PCH automatically performs failover operations to replace the primary with the spare. Moreover, the failover operation is transparent to the operating systems running on the platform's nodes.

Abstract: Embodiments help dynamically configure the width of PCIe links and also determine how to best configure the appropriate link width. This helps avoid situations where PCIe links are almost always active even at very low traffic rates. Embodiments achieve these benefits based on, for example, run-time monitoring of bandwidth requirement for integrated and non-integrated ports located downstream for the PCIe controller. This provides power savings with little impact on performance. Other embodiments are discussed herein.
