Abstract
The prefetch control is optimized according to a data pattern. The model selection unit selects inference units from outside of the device driver and replace each of the inference units according to the type of data analysis. The inference units, each of which is a neural network, predict an address region of the SSD based on I/O trace data collected by the device driver and instruct the device driver to prefetch from the outside based on the prediction result. The prefetch execution unit performs prefetch for the storage cache allocated to the SCM based on the prediction by a neural network associated with the query and the database.
