The profound heterogeneity, large volume, enormous complexity, and high velocity of scientific data and computing models impose unprecedented challenges in data analysis, storage, organization and understanding. These big data challenges are for both computer systems researchers who investigate new storage and computational solutions to support fast and reliable access to large datasets and domain scientists in various disciplines who critically rely on these datasets of vital scientific interest for knowledge discovery. In this talk, I will first overview the big data challenges due to its large volume, high velocity, and wide variety. Then I will talk about my research in data storage and I/O systems, particularly in erasure codes and solid-state devices (SSDs) to provide cost effective solutions for big data management to achieve high performance and reliability. I will conclude with my vision of collaborative research opportunities and plan in the era of big data.
