Data Protection Techniques in Large Storage Systems and Flash Memory Devices

Abstract: Today’s new “information age” is defined by exponential growth of the amount of data generated daily. Large data centers and distributed storage systems are becoming more widespread, and they play an increasing role in our everyday computational tasks. As a result, computer and system architecture research is facing new challenges. One such challenge is the task of restoring data lost due to disk failures, known as the repair problem. Classical codes like the Reed-Solomon ones are sub-optimal for distributed environments since their provide poor performance during the repair process. I will present several state-of-the-art constructions that form significantly better solutions for the repair problem. The differences between the constructions and their limitations will also be discussed.
