Recommended hardware

Recommended hardware requirements for an RDO cloud:

TripleO - Production (Zed or earlier)

Production deployments vary greatly but as a very brief guideline:

3 x controllers (minimum for HA control plane)
X number of compute nodes / hypervisors (can be scaled)
3 x Ceph storage nodes (optional, depending on requirements)
3 x Swift object storage nodes (optional, if not using RADOS)

TripleO Quickstart - Development (Zed or earlier)

Minimum 32GB of RAM
Minimum 120GB free disk space

Packstack - PoC

Minimum of 1 node, additional nodes for additional hypervisors
Minimum 16GB RAM for All In One deployment
