Latest Patents
One of Shipman's latest patents is for a hard disk drive with support for atomic transactions. This invention provides a data storage apparatus with features that facilitate atomic transactions more easily. Instead of requiring the host system to issue multiple logging commands, the data storage apparatus can perform the logging function itself. The design includes a receiving module for commands, a log recording module for nonvolatile storage, and an execution module to carry out the commands as an atomic transaction.
Another significant patent is for a read priority caching system and method. This invention addresses expected access times (EATs) of write requests to a disk drive, which measure the predicted service time for these requests. The disk drive modifies the EATs of write commands with a penalty, ensuring that read requests requiring disk access are prioritized. This innovative approach optimizes the performance of caching storage controllers.
