Abstract: A forward error correction (FEC) decoder is configured to find an alignment of a code block in a data stream by attempting to fully or partially decode one or more data windows of a predetermined size in the data stream. The predetermined size is a size of each codeword. The FEC decoder selects a first data window of the predetermined size, attempts to decode the first data window based on a particular error control coding method, and determines whether a valid codeword can be identified by attempting to decode the first data window. In response to determining that a valid codeword can be identified, the FEC decoder determines that an alignment of the codeword with the first data window is found. Otherwise, the FEC decoder selects a second data window of the predetermined size and attempts to decode the second data window.

Abstract: An approach to identifying a corrective action for a data storage device (DSD), such as one implemented in a fleet of DSDs in a data center, involves receiving error data about excursions from normal operational behavior of the DSD, inputting data representing a particular excursion into a probabilistic decision network which characterizes a set of DSD operational metrics and certain DSD controller rules that represent internal controls of the DSD and corresponding conditional relationships among the operational metrics, determining from the decision network the likelihood that one or more possible causes was a contributing factor to the particular excursion, and determining a corrective action for the particular excursion based on the determined likelihood of a particular cause of the one or more possible causes. The corrective action may then be shared with the DSD for in-situ execution of corresponding self-repair operations.
