Achieve High-Performance Storage with DAOS

Distributed Asynchronous Object Storage (DAOS) is an open source software stack that uses the fast I/O and data persistence of Intel® Optane™ persistent memory in combination with NVMe SSDs, to alleviate bottlenecks and drive storage performance in distributed environments.

DAOS offers dramatic improvements to storage I/O to accelerate HPC, AI, analytics, and cloud projects.

Meeting HPC Storage Performance Requirements

Intel® Optane™ PMem

Traditional storage relies on locking metadata in I/O blocks when processing requests from multiple compute nodes. DAOS stores metadata in bytes in Intel® Optane™ persistent memory, eliminating the latency from I/O block locking.

Intel® NVMe SSDs

Combined with NVMe SSDs, DAOS can take full advantage of PCIe direct connect speeds for microsecond storage I/O.


Persistent memory also mitigates the performance impact of write pressure in DAOS with low-cost NAND storage.

Intel® Xeon® Processors

Intel® Xeon® Scalable processors in storage clusters can improve DAOS performance with more memory channels and PCIe bandwidth.

Democratization of DAOS

The file system of choice for large scale HPC deployments targeting exascale compute performance, Colfax now offers DAOS with it's CXi series of server backed by world-class support, paving way for mainstream HPC deployment.

DAOS Starter Pack

The Colfax CX2265i-NVMe4-S16-X8 2U Rackmount Server powered by 3rd Gen Intel® Xeon® Scalable processors is the recommended hardware platform to run the DAOS server software. It combines Intel® Optane™ Persistent Memory (PMem) as Storage Class Memory (SCM) with U.2 NVMe SSDs for bulk data storage, and connects to the DAOS clients with two InfiniBand or high-performance Ethernet ports.
