Hot Spare

A hot spare or hot standby is used as a failover mechanism to provide reliability in system configurations. The hot spare is active and connected as part of a working system. When a key component fails, the hot spare is switched into operation. More generally, a hot standby can be used to refer to any device or system that is held in readiness to overcome an otherwise significant start-up delay.

Famous quotes containing the words hot and/or spare:

    Deacon King was tried for violating the Sabbath, and so hot was the debate that it was referred to the church council, which ultimately decided, after long and grave debate, that the deacon had committed a ‘work of necessity and mercy.’
    —For the State of Massachusetts, U.S. public relief program (1935-1943)

    My friend devotes himself to his life, whenever he can find the spare time. His motto is: ‘Don’t just sit there: live!’ So he’s too busy to stand, to walk, to do anything, except to live. He even refused to kiss a girl, when invited, on the grounds that it was time again to be living. Schedules are sacred to him.
    Marvin Cohen, U.S. author and humorist. The Self-Devoted Friend, New Directions (1967)
