  • System and method for transferring diagnostic data via a framebuffer
    Patent number: 11403162
    Abstract: An information handling system includes a first memory with a video framebuffer, which in turn includes a regular video framebuffer and a diagnostic video framebuffer. Detected errors within the information handling system are stored within the diagnostic video framebuffer. In response to the error log data being stored within the diagnostic video framebuffer, a processing unit provides a notification signal. In response to the notification signal, a baseboard management controller reads the error log data from the diagnostic framebuffer, and stores the error log data in a second memory of the baseboard management controller.

  • Variable read scan for solid-state storage device quality of service
    Patent number: 11385984
    Abstract: A method and apparatus for dynamically determining when, or how often, to do a read scan operation on a solid-state storage drive. One solution adjusts a read scan interval as part of performing a read scan operation. First, a bit error rate is determined for one of a plurality of storage blocks of a non-volatile memory array. Then, a cross temperature metric for the storage block is determined. A read scan interval is changed in response to the cross temperature metric satisfying a cross temperature threshold. Then, data in the storage block is relocated to a free storage block in response to the bit error rate satisfying a relocation threshold.

  • Byzantine agreement using communications having linear complexity
    Patent number: 11256581
    Abstract: The disclosure describes a failure-free execution agreement that includes n=3F+1 parties acting as replicas, and a number of parties acting as clients. One replica is designated as a primary. At most F replicas are presumed Byzantine faulty. The basic agreement protocol proceeds in three rounds: (1) client sends a request to the primary, who sends to all replicas; (2) each replica sends a threshold-part signature on hash to a first collector; (3) the collector combines the threshold-parts into a single signature and sends to all 3F+1 replicas which then commit and send to a second collector. The client proceeds when a signed block of requests arrives from the second collector.
