Zheng Dong is a notable inventor based in Shanghai, China. He has made significant contributions to the field of data storage and management. His innovative approach to data tiering has led to the development of a patented technology that optimizes storage use while efficiently handling data traffic.

Latest Patents

Zheng Dong holds a patent for a method titled "Data tiering with erasure coding using traffic estimation and feedback control." This computerized method determines erasure coding (EC) formats for data extents in storage systems. The process involves obtaining traffic history data of a data extent to be stored in the storage system. Estimated future traffic data is generated using a traffic estimation model, with the traffic history data provided as input. A current storage system constraint is calculated using the obtained traffic history data, and a constraint adjustment value is determined using a proportional, integral, derivative (PID) controller based on the current storage system constraint. An EC format for the data extent is then determined using the estimated future traffic data and the determined constraint adjustment value. The data extent is stored in the storage system using the determined EC format. This model and PID controller balance optimized storage use with efficient data traffic handling.
