METHOD FOR FILTERING CACHED INPUT/OUTPUT DATA BASED ON DATA GENERATION/CONSUMPTION

摘要

The present invention relates to a method of filtering a cache of input/output data. The method of the present invention comprises the steps of receiving an input/output transmission, calculating a rate of the sequential data stream when the input/output transmission is part of a sequential data stream and the total data transmitted as part of the sequential data stream is greater than a predetermined threshold. , when the input/output transmission is part of the sequential data stream and the total data transmitted as part of the sequential data stream is greater than a predetermined threshold, determining whether the transmission rate is greater than the throughput of a target storage device, and the transmission rate is the target and caching the I/O transmission when the throughput is greater than the throughput of the storage device and not caching the I/O transmission when the transmission rate is not greater than the throughput of the target storage device.
