The Container Cloud reference architecture uses the following hardware models:
Server - Supermicro 1U SYS-6018R-TDW
CPU - Intel Xeon E5-2620v4
Discrete NICs - Intel X520-DA2
- 1
Adding more than 3 nodes to a management or regional cluster is not supported.
- 2
Three

nodes for HA and threeworker storage
nodes for a minimal Ceph cluster. For more details about Ceph requirements, see Management cluster storage.- 3
A management cluster requires 2 volumes for Container Cloud (total 50 GB) and 5 volumes for StackLight (total 60 GB). A managed cluster requires 5 volumes for StackLight.

In total, at least 2 disks are required:
sda
- minimum 120 GB for systemsdb
- minimum 120 GB forLocalVolumeProvisioner
For the default storage schema, see Default configuration of the host system storage
