Designing DAOS Storage Solutions with Lenovo ThinkSystem SR630 V2 Servers

The Distributed Asynchronous Object Storage (DAOS) is an open source scale-out storage software stack that is designed from the ground up to support Storage Class Memory and NVMe storage in user space. The new Lenovo ThinkSystem SR630 V2 server with 3rd Gen Intel Xeon Scalable processors is an ideal 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.

This paper introduces the DAOS software stack, describes how to design DAOS storage servers with Lenovo ThinkSystem SR630 V2 servers, and provides guidelines for capacity sizing and performance sizing of DAOS storage solutions. It is intended for sales and technical sales specialists, solution architects, and storage administrators who need to understand the DAOS architecture in order to make informed DAOS sizing and configuration decisions. The paper will be most useful for technical professionals who have a working knowledge of high performance storage systems.
