Ceph Hardware Requirements
Ceph is designed to run on commodity hardware, which makes building and maintaining petabyte-scale data clusters flexible and economically feasible. When planning your cluster’s hardware, you will need to balance a number of considerations, including failure domains, cost, and performance. Hardware planning should include distributing Ceph daemons and other processes that use Ceph across many hosts. Generally, we recommend running Ceph daemons of a specific type on a host configured for that type of daemon. We recommend using separate hosts for processes that utilize your data cluster (e.g., OpenStack, OpenNebula, CloudStack, Kubernetes, etc).
As a Cloud Engineer or Storage Specialist, To design ceph cluster, you should design hardware based on types of services that you want.
