Description: The Bridges-2 Ocean data management system provides a unified, high-performance filesystem for active project data, archive, and resilience. Ocean consists of two tiers, disk and tape, transparently managed by HPE DMF as a single, highly usable namespace. Ocean's disk subsystem, for active project data, is a high-performance, internally resilient Lustre parallel filesystem with 15PB of usable capacity, configured to deliver up to 129GB/s and 142GB/s of read and write bandwidth, respectively. Ocean's tape subsystem, for archive and additional resilience, is a high-performance tape library with 7.2PB of uncompressed capacity (estimated 8.6PB compressed, with compression done transparently in hardware with no performance overhead), configured to deliver 50TB/hour.

Recommended Use: The Bridges-2 Ocean data management system provides high-performance and highly usable access to project and archive data. It is equally accessible to all Bridges-2 compute nodes, allowing seamless execution of data-intensive workflows involving components running on different compute resource types.

Access Description: Access is available through Bridges-2 (see Bridges-2 RM, EM, and GPU), including use of Globus and other file transfer protocols.
