  • Publication number: 20210405097
    Abstract: A baseboard management controller (BMC) installed in a server or other hardware device may perform operations to monitor and safeguard metering data for one or more hardware component of a server that includes the BMC. The BMC may periodically transmit a metering data message over a network to an event destination, where the metering data message includes the utilization levels of the hardware component during a period of operation. In response to detecting a loss of communication with the event destination, the BMC may perform lossy compression of the monitored utilization levels for the hardware component, wherein the lossy compression produces a utilization value that is representative of the monitored utilization levels, but uses less data storage capacity. The utilization value may be transmitted to the event destination instead of the monitored utilization levels in response to determining that communication with the event destination has been reestablished.

  • Patent number: 10180866
    Abstract: Effects of a physical memory fault are mitigated. In one example, to facilitate mitigation, memory is allocated to processing entities of a computing environment, such as applications, operating systems, or virtual machines, in a manner that minimizes impact to the computing environment in the event of a memory failure. Allocation includes using memory structure information, including, information regarding fault containment zones, to allocate memory to the processing entities. By allocating memory based on fault containment zones, a fault only affects a minimum number of processing entities.

  • Patent number: 9639269
    Abstract: A memory module stores a computing device type-specific parameter for each of a number of different types of computing devices. When the memory module is installed within a computing device, the computing device reads the computing device type-specific parameter for the particular type of computing device, and configures itself to use the memory module according to this parameter. As different types of memory modules become available, they are tested against different types of computing devices to determine the computing device type-specific parameter with which they should be programmed for each type of computing device.
