Abstract
One or more aspects of the present disclosure relate to paging metadata into memory. In embodiments, a metadata demand score is calculated for each extent of a storage array based on hit forecasts and read forecasts corresponding to input/output (IO) operations targeting each extent. Further, each extent can be ranked based on their respective metadata demand scores. Additionally, metadata can be paged into memory from a storage device of the storage array based on the ranking to reduce metadata page misses. For example, the memory can correspond to a global memory portion of the storage array.
