Cheap Paxos
Cheap Paxos extends Basic Paxos to tolerate F failures with F+1 main processors and F auxiliary processors by dynamically reconfiguring after each failure.
This reduction in processor requirements comes at the expense of liveness; if too many main processors fail in a short time, the system must halt until the auxiliary processors can reconfigure the system. During stable periods, the auxiliary processors take no part in the protocol.

Famous quotes containing the word cheap:
“Only be admonished by what you already see, not to strike leagues of friendship with cheap persons, where no friendship can be. Our impatience betrays us into rash and foolish alliances which no God attends.”
—Ralph Waldo Emerson (1803–1882)
