ABSTRACT:
A computer system enabling dynamic sparing employs a standby component which is identical to three other additional components and which operates like these other three active components while the computer system is running. Any one of these three other active components can be spared out dynamically in the computer system while it is running using a result of voting scheme and connecting of these four components in such a way that the system can dynamically spare while the system is still in operation. Such dynamic sparing gives the system a better reliability and availability when compared to today's computer system.
