What is Dell Watchdog Timer (WDT)?
Dell Watchdog Timer (WDT) is a built-in hardware watchdog timer designed to monitor the system for functional errors.This watchdog timer helps avoid system failures by resetting the system in the event of a lockup or hang. Adjustable threshold timers determine when a time-out error occurs and trigger a reset.
How does Dell Watchdog Timer work?
The Dell WDT tracks the execution of computer programs and systems, and checks if the system is still functioning properly. The timer must receive an affirmative response from each program or system after certain intervals of time. If the timer does not receive an affirmative response within a set time limit, it will assume that there's an issue with the computer or system and trigger a reset.
What are the benefits of using Dell Watchdog Timer?
The Dell WDT can help prevent server downtime by automatically resetting the server in case of processor or software failure. It also minimizes human intervention, which can be time-consuming in large server environments. The WDT also provides diagnostic information related to the cause of server resets.
