I have 12 servers running NT4, 2000 standard server, 2003 standard server on hardware boxes with age ranging 2-8 years. Once one of the old servers was 'shocked' when we had a power outage. Luckily I had a spare part to replace the motherboard. From that incident, I feel a surge protector might be helpful, but not sure. So I have the following questions:
1. What is the purpose of UPS? Usually battery can run only 5-7 minutes at full load.
2. Is UPS just good to have enough time to shut down servers nicely?
3. What UPS features are useful?
4. How can UPS shut down a server when it runs on battery?
Any comment is appreciated.
