Canonical Ceph hardware recommendations

This section outlines Canonical Ceph hardware specification recommendations. Following these configurations is highly recommended as a proven way to achieve the best price-performance.

Caution

Deviations from these specifications are possible, but they can affect both the overall storage performance and its total cost of ownership (TCO). We strongly recommend consulting Canonical before making any changes to the reference configurations and prior to purchasing any hardware.

Canonical provides different specifications based on cluster service placement architecture, i.e. hyperconverged or disaggregated. For hyperconverged nodes, we base our specifications on performance, capacity and general-purpose use cases. For disaggregated scenarios, we recommend specifications based on several combinations as per customer requirements, e.g. dedicated control plane nodes, dedicated RADOS Gateway (RGW) nodes, and dedicated Metadata server (MDS) nodes.

The Canonical Ceph hardware recommendation section provides infrastructure node recommendations for the different ways of deploying Canonical Ceph, i.e. via snap or charms. It also outlines memory and processor requirements, and provides software recommendations.
