Mastering Ceph

By: Nick Fisk

Overview of this book

Mastering Ceph covers all that you need to know to use Ceph effectively. Starting with design goals and planning steps that should be undertaken to ensure successful deployments, you will be guided through to setting up and deploying the Ceph cluster, with the help of orchestration tools. Key areas of Ceph including Bluestore, Erasure coding and cache tiering will be covered with help of examples. Development of applications which use Librados and Distributed computations with shared object classes are also covered. A section on tuning will take you through the process of optimisizing both Ceph and its supporting infrastructure. Finally, you will learn to troubleshoot issues and handle various scenarios where Ceph is likely not to recover on its own. By the end of the book, you will be able to successfully deploy and operate a resilient high performance Ceph cluster.

Benchmarking

Benchmarking is an important tool to quickly be able to see the effect of your tuning efforts and also determine the limits of what your cluster is capable of. However, it's important that your benchmarks reflect the type of workload that you would be running normally on your Ceph cluster. It is pointless to tune your Ceph cluster to excel in large block sequential reads and writes if your final intention is to run highly latency sensitive OLTP databases on it. If possible, you should try and include some benchmarks that actually use the same software as your real-life workload. Again in the example of the OLTP database, look to see if there are benchmarks for your database software, which will give the most accurate results.
