the most common fence in TCP connected systems is to disable the
ethernet ports of the fenced system, done via a 'smart ethernet
switch'. if you're using shared fiber storage, then you fence via the
fiber switch. a more extreme fence is to switch off the power to the
fenced system via a 'smart PDU'.
