Hi;

 

I know it is best practice to define 3 NTP servers for the Grid Members instead of two, but why is this the case. Also, what is the ideal number 4 or 5 for example?

 

 

Kindly

You need minimal 3. The reason is, if you have a 'false ticker' that would send a wrong time signal, your ntp

will be able to identify it. With only 2, it would not be able to know.

 

3 is good, 5 is perfect.
