Phobos

Phobos, standing for Parallel Heterogeneous OBject Store, is a tool designed to manage large volumes of data for various kinds of storage technologies from SSD to tapes. Phobos can efficiently handle very large datasets on inexpensive media without sacrificing scalability, performance, or fault-tolerance requirements.

Phobos is designed to allow the easy integration of new modules for layouts such as mirroring and erasure coding or I/O adapters.

Phobos is distributed under the GNU LGP Licence.

Main features

• Object storage using CRUD-like operations
• Designed primarily for magnetic tapes, but extended to POSIX filesystems, RADOS, etc.
• System metadata stored in PostgreSQL database
• Optimized access scheduling
• Fault-tolerance mechanisms
