Ceph recommendations and performance tuning

In this recipe, we will learn some performance tuning parameters for the Ceph cluster. These cluster-wide configuration parameters are defined in the Ceph configuration file so that each time any Ceph daemon starts, it will respect the defined settings. By default, the configuration file name is ceph.conf, which is located in the /etc/ceph directory. This configuration file has a global section as well as several sections for each service type.
