Abstract

Redundant Array of Independent Disks Level 6 (RAID-6) systems are critical for ensuring fault tolerance and data reliability in data centers, leveraging dual-parity calculations for data protection. Despite their benefits, these systems are also associated with high energy consumption, significantly impacting the carbon footprint of data facilities. This study evaluates the energy efficiency of three prevalent error correction codes—Reed-Solomon, Row-Diagonal Parity (RDP), and Liberation Codes—applied within RAID-6 systems. Through detailed comparative analysis, the research assesses how each code influences power consumption and computational demands. Initial findings indicate that integrating more efficient coding algorithms could substantially lower energy usage, thus enhancing green computing efforts. Future research aims to implement these optimizations in actual storage setups within cloud and high-performance computing settings, potentially reducing both operational costs and environmental impacts. This proactive approach seeks to align with the increasing demand for sustainable data management practices, offering significant benefits in energy savings and reinforcing the commitment to eco-friendly computing solutions.
