UPS configuration for 2 servers

[Anonymous user]

Hello, 

I am newbie in UPS configuration and I would like your opinion about the above situation.

At the moment we have 1 server which both of its PSU are connected with APC SMC1000I. We are going to purchase another one server and it is expected to get other 2 servers in due time. So I was thinking to build a UPS system which will charge/protect all my machines and to be expandable (in case I want to add more batteries).

Can you propose me such a configuration?

Thanks a lot!
