Red Hat Ceph Storage: Object storage performance and sizing guide

Red Hat Ceph Storage is a proven, petabyte-scale, object storage solution designed to meet the scalability, cost, performance, and reliability challenges of large-scale, media-serving, savvy organizations. Designed for web-scale object storage and cloud infrastructures, Red Hat Ceph Storage delivers the scalable performance necessary for rich media and content-distribution workloads.

While most of us are familiar with deploying block or file storage, object storage expertise is less common. Object storage is an effective way to provision flexible and massively scalable data storage without the arbitrary limitations of traditional proprietary or scale-up storage solutions. Before building object storage infrastructure at scale, organizations need to understand how to best configure and deploy software, hardware, and network components to serve a range of diverse workloads. They also need to understand the performance and scalability they can expect from given hardware, software, and network configurations.

This reference architecture/performance and sizing guide describes Red Hat Ceph Storage coupled with QCT (Quanta Cloud Technology) storage servers and networking as object storage infrastructure. Testing, tuning, and performance are described for both large-object and small-object workloads. This guide also presents the results of the tests conducted to evaluate the ability of configurations to scale to host hundreds of millions of objects.

After hundreds of hours of [Test ⇒ Tune ⇒ Repeat] exercises, this reference architecture provides empirical answers to a range of performance questions surrounding Ceph object storage, such as (but not limited to):

  • What are the architectural considerations before designing object storage?
  • What networking is most performant for Ceph object storage?
  • What does performance look like with dedicated vs. co-located Ceph RGWs?
  • How many Ceph RGW nodes do I need?
  • How do I tune object storage performance?
  • What are the recommendations for small/large object workloads?
  • What should I do? I’ve got millions of objects to store.

And the list of questions goes on. You can unlock the performance secrets of Ceph object storage for your organization with the help of the Red Hat Ceph Storage/QCT performance and sizing guide.
