Latest Patents
One of Alden's latest patents is an efficient system for predicting and processing storage subsystem failure. This invention allows for predictive failure analysis of a storage subsystem, enabling quick data recovery from a failed Read operation. The system is designed to work within a storage architecture that includes a host connected to a supervising processor, which in turn connects to a parity-equipped RAID storage subsystem. This subsystem consists of multiple Hard Disk Assemblies (HDAs), each containing an HDA controller and at least one storage medium. In one embodiment, when an HDA encounters an error during a Read attempt, it sends a recovery alert signal to the supervising processor. Subsequently, both the processor and the HDA initiate remote and local recovery processes simultaneously. The first process to complete successfully provides the data to the host, while the second process is aborted. Other embodiments of the patent include restrictions on HDA's predictive failure analysis operations to idle times and monitoring HDA errors at the supervisory processor level.
