Initial Experiences with DAOS Object Storage on Aurora
DescriptionThe storage subsystem of the Aurora platform at Argonne National Laboratory offers the potential for unprecedented application I/O performance. Its hardware stack combines NVMe drives, persistent memory devices, a large collection of storage servers, and a unified RDMA-capable network fabric. Its software stack is based on the DAOS object storage system, thereby putting into practice decades of I/O research into minimizing overhead, maximizing access concurrency, and streamlining application interfaces. Taken together, these elements combine to present up to 230 PiB of projected storage capacity and up to 31 TiB/s of projected I/O throughput to applications executing on Aurora.

We must revisit fundamental issues such as hardware topology, network concurrency, and I/O APIs to understand their impact on real-world I/O performance. In this paper we present our initial experiences with the DAOS storage system on Aurora and characterize its sensitivity to these parameters at small scale.
