## Abstract

A method for adjusting data processing unit (DPU) utilization of a storage array, the method includes sampling input-output (IO) of the storage array, forecasting, based on the sampling, demand for the storage array, where the storage array include a DPU core matrix, and making a first determination, based on the forecasting, that at least one service level (SL) of multiple SLs associated with the DPU core matrix is out of compliance. The method further includes identifying, based on the first determination, at least one DPU of the DPU core matrix currently operating at a first SL, and adjusting, based on the first determination, operation of the at least one DPU to operate from the first SL to a second SL of the multiple SLs.
