Sample Scenario
How we tested
Specifications

Company: MadCat Internet
This ISP needs a rack-mountable UPS to run seven servers and three switches.

Approximate budget: AU$5000
Requires: One rack-mountable UPS with 10 power ports.
Concerns: The company wants to be sure the UPS will provide enough power to let all the servers shut down gracefully in the event of a failure. The company will also look into how the UPS communicates with the servers, the UPS management software, and the availability of hot-swappable parts.

Best Solution: APC Smart-UPS 3000
The APC would once again be the best choice here, though closely followed by the PowerWare 5125. Both systems have excellent running time and cost-per-minute ROI, but the APC wins with slightly better software and the fact that we have actually been able to see and test its network solution.
