Chapter 5. Minimum hardware recommendations for containerized Ceph
Ceph can run on non-proprietary commodity hardware. Small production clusters and development clusters can run without performance optimization with modest hardware.
NOTE: * Consider future growth and usage patterns when allocating disk space.
- Regularly monitor disk usage and performance to address any storage limitations.
- Configuring swap space for virtual memory for daemons is generally not recommended in modern systems. This approach can degrade performance, and your Ceph cluster may operate more effectively with a daemon that crashes rather than one that becomes unresponsive.
Hardware accelerated compression in Ceph Object Gateway requires RHEL 9.4 on a Sapphire or Emerald Rapids Xeon CPU (or newer) with QAT devices. For more information, see Intel Ark.
| 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. | |

Optional, but Red Hat recommended, 1x SSD or NVMe or Optane partition or lvm per daemon. Sizing is 4% of | |

| Disk Space Allocation | Create a dedicated Storage Partition Size for /var/lib/ceph with a minimum size of 120 GB; 240 GB is recommended. If a dedicated partition is not feasible, ensure that /var is on a dedicated partition with at least the above-mentioned free space. | |

This number is highly dependent on the configurable MDS cache size. The RAM requirement is typically twice as much as the amount set in the | |
| Disk Space Allocation | As a best practice, create a dedicated partition for /var/log with a minimum of 20 GB of free space for this service. If a dedicated partition is not possible, ensure that /var is on a dedicated partition with at least the above-mentioned free space. | |
| Network | 2x 1GB Ethernet NICs, 10 GB 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. |
