PASSI: A Parallel, Reliable and Scalable Storage Software Infrastructure for active storage system and I/O environments

Storage systems are a foundational component of computational, experimental, and observational science today. The ever-growing size of computation and simulation results demands huge storage capacity, which challenges the storage scalability and causes data corruption and disk failure to be commonplace in exascale storage environments. Moreover, the increasing complexity of storage hierarchy and passive storage devices make today's storage systems inefficient, which force the adoption of new storage technologies. In this position paper, we propose a Parallel, Reliable and Scalable Storage Software Infrastructure (PASSI) to support the design and prototyping of next-generation active storage environment. The goal is to meet the scaling and resilience need of extreme scale science by ensuring that storage systems are pervasively intelligent, always available, never lose or damage data and energy-efficient.
