Peta- and exascale computing infrastructures make unprecedented demands on storage capacity, performance, concurrency, reliability, availability, and manageability. This one-day workshop focuses on the data storage and management problems and emerging solutions found in peta- and exascale scientific computing environments, with special attention to issues in which community collaboration can be crucial for problem identification, workload capture, solution interoperability, standards with community buy-in, and shared tools. Addressing storage media ranging from tape, HDD, and SSD, to new media like NVRAM, the workshop seeks contributions on relevant topics, including but not limited to: performance and benchmarking failure tolerance problems and solutions APIs for high performance features parallel file systems high bandwidth storage architectures support for high velocity or complex data metadata intensive workloads autonomics for HPC storage virtualization for storage systems archival storage advances resource management innovations incorporation of emerging storage technologies
