~~~~
When you colocate two containerized Ceph daemons on a same node, the ceph-ansible playbook reserves dedicated CPU and RAM resources to each. By default, ceph-ansible uses values listed in the {hardware_guide}#ceph-hardware-min-recommend[Recommended Minimum Hardware] chapter in the Red Hat Ceph Storage Hardware Selection Guide 3. To learn how to change the default values, see Section 2.2, “Setting Dedicated Resources for Colocated Daemons”.
