Chapter 7. Recommended Minimum Hardware for Containerized Ceph Clusters
Ceph can run on non-proprietary commodity hardware. Small production clusters and development clusters can run without performance optimization with modest hardware.
| Process | Criteria | Minimum Recommended |
|---|---|---|
|
| Processor | 1x AMD64 or Intel 64 CPU CORE per OSD container |
| RAM | Minimum of 5 GB of RAM per OSD container | |
| OS Disk | 1x OS disk per host | |
| OSD Storage | 1x storage drive per OSD container. Cannot be shared with OS Disk. | |
| Journal | 1x SSD/NVME partition per daemon if using dedicated device | |
| Network | 2x 1GB Ethernet NICs (10GB Recommended) | |

| Network | 2x 1GB Ethernet NICs (10GB Recommended) Note that this is the same network as the OSD containers. If you have a 10 GB network on your OSDs you should use the same on your MDS so that the MDS is not disadvantaged when it comes to latency. |
