As mentioned earlier, performance tuning is mostly environment-specific. Your organization environment and hardware infrastructure for Ceph cluster will be a lot different from other organizations. Things you tune for your Ceph cluster may or may not work the same way as in other environments. In this section, we will discuss some general performance tuning parameters that you can tailor more specifically for your environment.
The parameters mentioned in this section should be defined under the [global] section of your Ceph cluster configuration file.
It's highly recommended that you use two physically separated networks for your Ceph cluster. Each of these networks has their own set of responsibilities. Under Ceph's terminology, these networks are referred to as public and cluster networks:
The public network is also referred to as the client-side network that allows clients to communicate with Ceph clusters and access the cluster...
