Red Hat Training
A Red Hat training course is available for Red Hat Ceph Storage
Chapter 6. Recommended Minimum Hardware
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 |
| Nodes | Minimum of three nodes required. | |
| RAM | For FileStore OSDs, Red Hat typically recommends a baseline of 16 GB of RAM per OSD host, with an additional 2 GB of RAM per daemon. For BlueStore OSDs, Red Hat typically recommends a baseline of 16 GB of RAM per OSD host, with an additional 5 GB of RAM per daemon. | |
| OS Disk | 1x OS disk per host | |
| Volume Storage | 1x storage drive per daemon | |
| Journal | Optionally, 1x SSD partition per daemon | |
|
|
Optional, but Red Hat recommended, 1x SSD or NVMe or Optane partition or lvm per daemon. Sizing is 4% of | |

Optionally, 1x SSD or NVMe or Optane partition or logical volume per daemon. Use a small size, for example 10 GB, and only if it’s faster than the | |
| Network | 2x 1GB Ethernet NICs | |
|
| Processor | 1x AMD64 or Intel 64 |
| Nodes | Minimum of three nodes required. | |
| RAM | 1 GB per daemon | |
| Disk Space | 10 GB per daemon (50 GB recommended) | |
| Monitor Disk |

| Network | 2x 1 GB Ethernet NICs | |
|
| Processor | 1x AMD64 or Intel 64 |
| RAM | 1 GB per daemon | |
| Disk Space | 5 GB per daemon | |
| Network | 1x 1 GB Ethernet NICs | |
|
| Processor | 1x AMD64 or Intel 64 |
| RAM | 2 GB per daemon
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 | 2 MB per daemon, plus any space required for logging, which might vary depending on the configured log levels | |
| Network | 2x 1 GB Ethernet NICs Note that this is the same network as the OSDs. 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. |
