The Distributed Asynchronous Object Storage (DAOS) is an open source scale-out storage system that is designed from the ground up to support NVMe storage in user space. DAOS can run over any TCP network, but it can also take advantage of high performance fabrics like 100/200/400 Gbps Ethernet, InfiniBand, Slingshot, or Omni-Path. This paper describes the networking architecture of DAOS and discusses scaling and performance aspects of running DAOS over those high performance fabrics.

摘要

The Distributed Asynchronous Object Storage (DAOS) is an open source scale-out storage system that is designed from the ground up to support NVMe storage in user space. DAOS can run over any TCP network, but it can also take advantage of high performance fabrics like 100/200/400 Gbps Ethernet, InfiniBand, Slingshot, or Omni-Path. This paper describes the networking architecture of DAOS and discusses scaling and performance aspects of running DAOS over those high performance fabrics.
