Abstract
The operation of a shadow processor for a system having redundant controllers is arranged so that it receives a FIFO fill indicator from another shadow processor associated with that one of the controllers that is in a standby mode, and, if the value of the indicator reaches a predetermined value, then the shadow processor throttles the data writing activity of the active controller for an amount of time sufficient to allow the other shadow processor time to unload the FIFO below a particular fill level.
