    Abstract: Aspects extend to methods, systems, and computer program products for remediating power loss at a server. Aspects of the invention increase the likelihood of gracefully shutting down a server and associated components in a data center when mains power is lost for a specified amount of time (e.g., an amount of time beyond transition to generator power). A server can include a management module (e.g., a BMC) and a watchdog module. When the management controller detects loss of power at a power supply unit, the management controller orchestrates a graceful shutdown of the server in response to power loss. When the management module is unresponsive, the watchdog module provides backup functionality for orchestrating a graceful shutdown in response to power loss. As such, data can be saved from RAM to more durable storage even when the management module is unresponsive.

    Abstract: Various techniques for managing power backup for computing devices are disclosed herein. In one embodiment, a method includes receiving data representing a backup capacity of one or more backup power units and data representing a backup power profile of one or more processing units sharing the one or more backup power units. A portion of the backup capacity may then be assigned to each of the one or more processing units based at least in part on both the received data representing the backup capacity of the one or more backup power units and the received data representing the profile of the one or more processing units.

    Abstract: A memory management system includes a physical memory associated with a computing device and a memory manager. The memory manager is configured to manage a shared memory cache as part of a compression of the physical memory using a cache compression algorithm, wherein a compression block size for the compression is a single cache line size. The physical memory includes a sector translation table (STT) region and a sector memory region. The memory manager uses a memory descriptor defined by an STT entry having a cache line map and a plurality of sector pointers to load cache from the physical memory to a level 3 Cache. The cache line map contains cache line metadata including a size of each cache line, a location of the cache line in one of the sectors pointed to by the STT entry, and a plurality of flags.
