+In its default configuration, Ironic runs a periodic task to synchronize the
+power state of the managed physical nodes with the Ironic database. For the
+hardware type ``ipmi`` (see :doc:`/admin/drivers/ipmitool`) and depending on
+the number of nodes, the network connectivity, and the parallelism of these

+case too many power sync failures occur in the section on
