Attendees of this presentation will learn how to use several open source tools ( https://github.com/jharriga/ ) to evaluate object storage platforms. These tools provide automation and customer-based object storage workloads for activities such as filling a cluster, aging a cluster and running steady-state mixed operation workloads. One of the tools, RGWtest, automates pool creation, logs cluster statistics such as system resource utilization (CPU and memory) and submits workloads through COSbench - Intel’s open source object storage benchmark tool. A demonstration of the tools will be part of the presentation. Learning Objectives: 1) How to install, configure and execute the object storage workload tools; 2) How to interpret workload run results; 3) How to design and size object storage workloads.
