Latest Patents

One of Leihu Zhang's latest patents is a method, device, and computer program for data storage. This innovation involves selecting a stream from multiple streams with respective update frequencies. The update frequency of the selected stream matches that of the data to be written. The process includes determining a label for the data based on the selected stream's label and sending a write request to a storage system. This request comprises the data label, allowing the storage system to perform a write operation based on the identified stream. This technique effectively reduces the write amplification factor, thereby increasing the effective life of storage devices and improving the read and write performance of the storage system.

Another notable patent focuses on optimized access to high-speed storage devices. This technique involves determining a target storage device for an input/output (I/O) request received by a storage system. If the target device is of a first type, the I/O request is processed by accessing the memory of the storage system. Conversely, if the target device is of a second type with a higher access speed, the I/O request is processed without accessing the memory. This innovation significantly enhances the performance of the storage system.
