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 manager nodes for HA and three worker 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.

4

In total, at least 3 disks are required:

  • sda - minimum 60 GB for system

  • sdb - minimum 60 GB for LocalVolumeProvisioner

  • sdc - for Ceph OSD

For the default storage schema, see Default configuration of the host system storage

5

Only one PXE port per node is allowed. OOB management (IPMI) port is not included.
