Ceph was designed to run on commodity hardware, which makes building and maintaining petabyte-scale data clusters economically feasible. When planning out your cluster hardware, you will need to balance a number of considerations, including failure domains and potential performance
At least three Ceph Monitor nodes are required. The number of monitors should always be odd (1+2n). 4 GB of RAM. Processor with four logical cores. An SSD or other sufficiently fast storage type is highly recommended for monitors, specifically for the /var/lib/ceph path on each monitor node, as quorum may be unstable with high disk latencies.
2 GHz per OSD daemon process is recommended. Note that Ceph runs one OSD daemon process per storage disk; do not count disks reserved solely for use as OSD ...
hardware under load and generates essential performance and sizing data for diverse workloads— ultimately simplifying Ceph storage cluster hardware selection. As discussed in this guide, multiple hardware vendors now provide server and rack-level solutions optimized for Red Hat Ceph Storage
