Abstract
A method or system for managing data placement in multi-tier storage devices. The system monitors usage of data items stored across storage devices, each associated with a performance tier. The system collects usage metrics for the data items, including access frequency, recency, file size, growth rate, sequentiality, or temporal access patterns. Multiple tiering methods are executed in parallel, with each method analyzing at least a subset of the usage metrics to generate tiering recommendations. These recommendations indicate whether each data item should be promoted to a higher-performance tier, demoted to a lower-performance tier, or retained in its current tier. The system aggregates the outputs of the tiering methods to compute a consensus decision for each data item. Based on the consensus, the system relocates data items to appropriate storage tiers.
