Welcome to DAOS!

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

In addition to on-prem deployments, DAOS can be deployed in cloud environments. More information on cloud deployments is available in the DAOS in the Cloud section.

The included document versions are associated with DAOS v2.2. They may also describe features that are currently under development for a future DAOS release. Those features will be clearly marked as such.

Warning

DAOS v2.2 is under active development. Use at your own risk. Please consider a stable DAOS release (i.e., 2.0.x) for production deployments.
