What UPS and surge protector do I need?

Hi,
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.

1) UPS protects against black/brown outs...many of the better ones protect against surges/spikes as well.  Depending on the equipment housed on the UPS, you can sometimes get runtimes up to 30-60 minutes...if you're not getting the bare minimum, you'll need additional UPS devices...
2) Most of today's UPS devices (We use APC) will have 'smart' monitoring software that will denote that the power source is removed and will send a 'shutdown' command to the server when it approaches the run-time threshhold
3) Email notification can also be beneficial...particularly to SMS-capable pagers/cell phones
4) See #2

5) Normally the associated software will give you an indication of that...some even have LED meters on the front of the device to give you a rough estimate
6) "Sometimes".  For instance - on the models we use APC 2200 series include a 'smart' monitoring port, when monitoring only one server.  To provide monitoring for additional servers, you need to purchase an expansion interface card that slides into the back of the unit.  There may be other models that include multiple ports for multiple servers, but you'd need a port connection of some kind between the unit and the monitored devices...(usually through the com/serial port).
7) Not sure I understand
8) APC is, imo, one of the frontrunners in the market - they have some great products...www.apc.com

Good luck!
