Management cluster storage

The management cluster requires minimum two storage devices per node. Each device is used for different type of storage.

• The first device is always used for boot partitions and the root file system. SSD is recommended. RAID device is not supported.

• One storage device per server is reserved for local persistent volumes. These volumes are served by the Local Storage Static Provisioner (local-volume-provisioner) and used by many services of Container Cloud.

You can configure host storage devices using the BareMetalHostProfile resources. For details, see Customize the default bare metal host profile.
