In this paper, we present our vision on building large-scale storage systems from commodity components in a data center. For reasons of efficiency and flexibility, we advocate maintaining sophisticated data management functions behind a block-based interface. We anticipate that such an interface can be customized to meet the diverse needs of end-users and applications through the extensible storage system architecture that we propose.
