The Distributed Asynchronous Object Storage (DAOS) is an open-source software-defined object store designed from the ground up for massively distributed Non Volatile Memory (NVM). DAOS takes advantage of next generation NVM technology like Storage Class Memory (SCM) and NVM express (NVMe) while presenting a key-value storage interface and providing features such as transactional non-blocking I/O, advanced data protection with self-healing on top of commodity hardware, end-to-end data integrity, fine-grained data control and elastic storage to optimize performance and cost.

DAOS is licensed under the Apache License Version 2.0. Please see the LICENSE & NOTICE files for more information.

The DAOS documentation is available online.

This includes:

• DAOS architecture overview
• Admin guide to install, manage and monitor a DAOS system.
• User guide documenting the DAOS native API, as well as the integration with HDF5, Spark, and POSIX.
• Developer documentation to learn more about DAOS internals and contribute to the development effort.
