The invention relates to the technical field of data storage, and discloses an intelligent hierarchical storage method and
system for cold and hot data of a
solid state disk, and the method comprises the steps: collecting spatial position change data and vibration state data, and carrying out the preprocessing to obtain a multi-dimensional
feature data set; performing quantification
processing on the influence degree of the spatial position change data and the vibration state data to obtain an interference
weight value; constructing a joint
feature matrix based on the interference
weight value and the historical access
record, and predicting hotspot data distribution; if the matching degree of the hotspot data distribution and the current storage
layout is lower than a preset matching degree threshold value, migrating the high-frequency access data to a low-
delay area to obtain an optimized storage
layout; when the access
response time is larger than a preset time threshold value,
log data are generated, and
delay load features are extracted; and carrying out secondary adjustment on the optimized storage
layout to obtain a final
dynamic storage scheme. According to the method, dynamic optimization of the storage performance of the
solid state disk can be realized, and
delay loss caused by cold and hot data mismatching is reduced.
