Description
In the era of exascale computing and data-intensive workflows, efficient tiered storage architectures are essential to balance performance, capacity, and cost. While parallel file systems like Lustre, BeeGFS, and DAOS excel at handling high-throughput I/O, the seamless integration of high-capacity, long-term storage solutions such as tape libraries remains a major challenge for long-term data retention and cost-effective archiving.
This talk presents Phobos, an open-source storage system developed by CEA, specifically designed to address these challenges by providing a highly efficient, scalable, and vendor-neutral solution for managing tape-based archives and large robotic libraries. Built on the Linear Tape File System (LTFS) —an open, standardized format— Phobos ensures interoperability, long-term data preservation, and independence from proprietary formats and software, making it a cornerstone for data sovereignty. Phobos offers multiple front-ends, including Lustre/HSM, S3, and iRODS, enabling seamless integration in diverse HPC, cloud, and data management environments.
