Reducing the power consumption of storage systems is now considered a major issue, alongside the maintenance of system reliability, availability, and performance. In this paper, we propose a method named as the Replica-assisted Power Saving Disk Array (RAPoSDA) to reduce the electrical consumption of storage systems. RAPoSDA utilizes a primary backup configuration to ensure system reliability and it dynamically controls the timing and targeting of disk access based on individual disk rotation states. We evaluated the effectiveness of RAPoSDA by developing a simulator that we used for comparing the performance and power consumption of RAPoSDA with Massive Arrays of Inactive Disks (MAID), which is a well-known power reduction disk array. The experimental results demonstrated that RAPoSDA provided superior power reduction and a shorter average response time compared with MAID.
