DAOS Project Update
DescriptionThe Distributed Asynchronous Object Storage (DAOS) is an open source scale-out storage system that is designed from the ground up to support Storage Class Memory (SCM) and NVMe storage in user space. This PDSW23 WiP session highlights two new technologies that are available in the recently released DAOS 2.4: The “Metadata on SSD” code path that enables DAOS servers without Optane Persistent Memory, and a new runtime interception library that can intercept both data and metadata calls of legacy POSIX applications to redirect them to DAOS File System (DFS) calls.
