Controller Disk Configurations for All-in-one Systems¶
For StarlingX Simplex and Duplex Systems, the controller disk configuration is highly flexible to support different system requirements for Cinder and nova-local storage.
You can also change the disk configuration after installation to increase the persistent volume claim or container-ephemeral storage.
