“An Integer Programming Power Optimization in Storage Systems”

This paper presents a linear integer programming framework for effective power management in storage systems. A sample memory system with different data banks is considered for optimal energy consumption during data operations by manipulating the data among banks. The memory bank four-level power state schemes, namely, active, stand-by, nap, and power down states, are included for superior power management of the storage system by formulating a linear integer optimization framework that includes plausible data manipulations, energy consumption levels, data migration, and compression options. The numerical results illustrate the efficiency of the proposed framework in terms of power management of storage systems with respect to available approaches with two-level power state operations.
