Abstract: The disclosure herein describes training and using an uncorrectable error (UE) state prediction model based on telemetry error data. Sets of UE state labels and non-UE state labels are generated from a first set of collected telemetry data, wherein the UE state labels each reference a UE and telemetry data of an interval prior to the referenced UE. Statistical features are extracted from telemetry data of the sets of UE state labels and non-UE state labels, and the extracted statistical features are used to train a UE state prediction model. A second set of collected telemetry data is obtained, and a UE event is predicted based on the second set of collected telemetry data using the trained UE state prediction model. A preventative operation is performed on a memory page of the system based on the predicted UE event, whereby the predicted UE event is prevented from occurring.

Abstract: Systems and methods for testing non-volatile storage devices are disclosed that provide functionality to control when testing of the non-volatile storage device is performed. In one embodiment, information stored in persistent memory indicates whether testing is enabled or disabled. For example, the testing information may indicate that testing is to be performed upon a first initialization of a non-volatile storage device, but not in connection with subsequent power-up events. Furthermore, functionality is disclosed for re-running and/or bypassing testing of the non-volatile storage device.

Abstract: A solid-state storage system is described with a method for adjusting the frequency of data retention operations. The data retention operation frequency can be increased or decreased according to a variety of environmental factors such as error code frequency, system temperature, altitude, and other operating conditions. These factors can indicate an increased or decreased risk of failure and accordingly provide increased or decreased rates of data retention operations.

Abstract: A method and apparatus for correlating the identities of hardware devices, such as processors or memory controllers, between a local operating system and a global management entity is described. In an embodiment a fault message including a local identifier of a faulting device is received from an operating system. A global identifier of the faulting device is determined that is different from the local identifier. An appropriate replacement device is then selected based on the global identifier of the faulting device, and the selected replacement device is mapped to the faulting device.

Abstract: A method and apparatus for correlating the identities of hardware devices, such as processors and memory controllers, between a local operating system and a global management entity is described. When the operating system detects a faulting device, the operating system generates a fault message and transmits the fault message to the global management entity. The global management entity determines the identity of the faulting device based on information contained in the fault message, selects an appropriate replacement device, changes a routing table to map to the replacement device to the identity of the faulting device, and transmits to the operating system a global identity of the replacement device. The operating system correlates the local identity of the replacement device with the global identity of the replacement device.

Abstract: Disclosed herein is a tool for stretching wire and similar such devices commonly used in the repair or fabrication of wire fencing. The structure according to the present invention is defined by a pivot point, an arcuate handle attached to the pivot point and opposed hooks disposed at extremities of the handle whereby the wire can be tensioned and refastened to a post with only one person operating the tool and reaffixing the wire.
