Latest Patents

One of Zhang Wu's latest patents is titled "Tiered storage optimization and migration." This invention encompasses systems, methods, and computer program products designed to automate the management of tiered storage systems. It aims to improve the service life and reduce costs associated with flash-based storage devices. The innovative approach utilizes time series learning models to predict the write frequency of each data block for the upcoming cycle. By leveraging these predictions, the management of the tiered flash-based storage system can automatically organize and migrate stored data based on various factors, including storage costs and access frequency. Data that is frequently accessed is migrated to high-end flash-based storage devices, while less frequently accessed data is moved to more economical, low-end devices.

Another significant patent by Zhang Wu is related to "White box testing." This invention involves scanning the source code of a software artifact to generate a call tree model. By executing a set of test cases against the software artifact, log data is collected, allowing for the detection of untested leaf nodes. Subsequently, a new set of test cases is generated to cover these untested nodes, enhancing the overall testing process.
