Big data applications have imposed unprecedented challenges in data analysis, storage, organization and understanding due to their heterogeneity, volume, complexity, and high velocity. These challenges are for both computer systems researchers who investigate new storage and computational solutions to support fast and reliable access to large datasets and application scientists in various disciplines who exploit these datasets of vital scientific interest for knowledge discovery. Compared to hard disk drives, NAND flash-based solid state drives (SSDs) exhibit better performance, particularly on random workloads. Over the past decade, SSDs have been gaining popularity in massive storage. This trend is attributed to increasing storage density resulting from scaling manufacturing process technology, as well as the employment of multi-level cell (MLC) techniques. However, the deployment of SSDs in enterprise storage systems or data centers is still limited due to SSD endurance and reliability concerns.
In this talk, I will first outline my research in data storage and I/O systems, then discuss the challenges of SSDs in data centers, and present our solutions to high performance and reliable flash storage.
