The process of replacing a component (e g , disk drive, controller, fan, power source) with a new component while the rest of the system continues functioning without interruption
The ability of a device to have parts removed after, for example, a slot-in card or fan failure, without affecting its operation Many of today's hubs offer hot swapping without bringing down the network to charge a component
A component may be pulled from a system and plugged into a new one while the power is still on and the unit is still operating Redundant systems can be designed to allow the hot swapping of drives, circuit boards, power supplies, and most any component
refers to the ability to remove a failed member of a redundant disk array and replace it with a good drive without bringing down the server or interrupting transactions that involve other devices [ top]
