  • Publication number: 20170235682
    Abstract: A volatile/non-volatile memory device access provisioning system includes a processing system and a controller coupled to a memory device. The controller provides an access key to the memory device and causes memory device communications to be passed to the processing system when the access key is available. The controller simply causes memory device communications to be passed to the processing system when the access key is not available. The memory device masks non-volatile memory subsystem access information in the memory device to prevent the processing system from accessing non-volatile memory subsystem(s) in the memory device, and then determines whether the access key has been received from the controller. The memory device will unmask the non-volatile memory subsystem access information such that the processing system can access non-volatile memory subsystem(s) in response to determining that the access key has been received from the controller.

  • Patent number: 9699933
    Abstract: A server rack includes a power mapping module, a power receptacle that includes a power tine communication module wherein the power receptacle is uniquely associated with a rack unit of the server rack and is collocated with the associated rack unit, and a server coupled to the power mapping module via a management network, wherein the server asserts an interrupt request to the power mapping module via the management network. The power mapping module sends a unique identifier via the first power tine communication module in response to receiving the interrupt request. The server receives the unique identifier via the second power line communication module and sends the unique identifier to the power mapping module via the management network. The power mapping module determines that the server is installed into the rack based upon the receipt of the unique identifier.

  • Publication number: 20170154005
    Abstract: An information handling system includes a host processing complex and a wireless management system. The host processing complex instantiates a hosted processing environment and includes a first general-purpose processing unit (GPU) and a GPU hot-plug module that enables a hot-plug operation to replace the first GPU with a second GPU while power is provided to the host processing complex. The hosted processing environment instantiates a first workload on the first GPU. The wireless management system operates out of band from the hosted processing environment, directs the hosted processing environment to halt the first workload, and directs the GPU hot-plug module to perform the hot-plug operation.
