Overview of this book

Ceph is a unified distributed storage system designed for reliability and scalability. This technology has been transforming the software-defined storage industry and is evolving rapidly as a leader with its wide range of support for popular cloud platforms such as OpenStack, and CloudStack, and also for virtualized platforms. Ceph is backed by Red Hat and has been developed by community of developers which has gained immense traction in recent years. This book will guide you right from the basics of Ceph , such as creating blocks, object storage, and filesystem access, to advanced concepts such as cloud integration solutions. The book will also cover practical and easy to implement recipes on CephFS, RGW, and RBD with respect to the major stable release of Ceph Jewel. Towards the end of the book, recipes based on troubleshooting and best practices will help you get to grips with managing Ceph storage in a production environment. By the end of this book, you will have practical, hands-on experience of using Ceph efficiently for your storage requirements.

Baseline network performance

In this recipe, we will perform tests to discover the baseline performance of the network between the Ceph OSD nodes. For this, we will be using the iperf utility. Make sure that the iperf package is installed on the Ceph nodes. iperf is a simple, point-to-point network bandwidth tester that works on the client-server model.

To start network benchmarking, execute iperf with the server option on the first Ceph node and with the client option on the second Ceph node.

How to do it...

Using iperf, let's get a baseline for our clusters' network performance:

  1. Install iperf on the ceph-node1 and ceph-node2:

        # sudo yum install iperf -y
  1. On ceph-node1, execute iperf with -s for the...
