With a total of 5 patents to her name, her work has had a substantial impact on improving data processing and storage efficiency.

Latest Patents

One of her latest patents is titled "Identification of substitute controllers based on temperature data." This invention describes a storage system that comprises a cluster of storage controllers communicatively coupled to a storage device. Each storage controller is associated with a storage namespace in the storage device to process I/O operations of the associated storage namespace. The I/O processing engine allocates I/O queues to each storage controller from the cluster for processing I/O operations. It identifies a heated controller based on temperature data and suspends I/O queues handled by that controller. Additionally, it selects a substitute controller based on the temperature data and allocates additional I/O queues for processing.

Another notable patent is "Fault management in NVMe systems." This invention outlines systems and methods that enable host bus adapter (HBA) drivers to detect delays in executing input/output (I/O) commands in urgent-priority queues. The system automatically identifies the lower-priority queue causing the delay and mitigates it by throttling and migrating the lower-priority queue to a controller that applies a different arbitration mechanism.
