Hot swapping
RAID Recovery - Hot swapping
The term hot swapping describes its capability to function as well as replace system components such as the hard drive, CD-ROM, Power supply, or with some similar other devices because of a device failure or for storage devices or to reserve some other data. It remains working while the system is on. Hot swap can change the components without essential interruptions to the system.
Hot swap, while works, offers a rack or enclosure for the device that provides an appearance to the computer’s bus or I/O controller so that device, after replacement, can still b e there. Hot swap arrangements are available for SCSI and IDE hard drives and hot swap versions RAID are also accessible. Sometimes it is provided where lot of devices are shared in local network devices.
Reason for hot-swapping:
If any significant changes of configuration or repairing any working system are required, hot swapping can solve the problem properly without disturbing its operation. It is very convenient for avoiding any disturbances of shutting down and restarting the complex equipment.
How swapping is commonly used to add or remove the components and permits a device to match data with computer or replaces the faulty modules without interrupting function of any equipment.
Equipments might be structured with redundancy to let the other parts of the system continue with their own function in case of any component failure, or any replacement takes place. For example, RAID disk arrays allow faulty disks to be hot swapped for the new one which is specially configured to become a part of the array automatically by the command of users. A machine can have double power supplies and every one can provide to power the machine and faulty one can possibly hot-swapped.
