Storage is a an optional feature that enables one or more pairs of storage nodes that are especially configured for intense DB writing and storing data.

On the storage nodes MariaDB comes with dedicated configuration tuned for extensive writing. Currently storage nodes can be used to redirect and store voisniff traffic from the PRO nodes or the CARRIER db nodes.

From the running processes perspective on the storage nodes there is only MariaDB running (as well as usual mandatory processes like rsyslog, systemd-timesyncd, ssh and alike).
