I inherited a UPS that was running a small windows server and one Win 7 machine and since I came on board we have upgraded our equipment significantly. We have 2 Dell R720 running hyper V and hosting 4 VM servers, to Sonicawall firewalls in a high availability configuration, Backup device, couple of switches and and about 3 other small devices. I am almost positive that the APC smart UPS 1500 that we have now would not be enough for this setup.
I would like to purchase something that would run this equipment for a few hours without spending an arm and a leg but I am having a bit of a hard time converting wattage to VA and determining what is actually needed.
any suggestions?
