Your first setup (with the Y cable) is the basic idea for a parallel UPS system, but you won't actually use a Y-cable; the UPSes would be hard-wired to an external paralleling system which should also provide a bypass connection -- basically a circuit breaker panel used in reverse. The UPSes would also need to communicate with each other to stay in sync for ...

I'd recommend sizing for the runtime and protections you actually require. Please look into extended-runtime UPS solutions compatible with your units. You can add extra runtime via additional batteries. Is all of your equipment on dual power supplies? Are the power distribution modes configurable on the servers?

Not sure if you saw this site, or if it just doesn't quite meet what you're needing... essa.us.dell.com seems to have almost exactly what you're asking for, unless I'm missing something. Input your cost per kWh, select a system/solution, configure your usage (Transactional / Computational / Memory Intensive, and CPU load), and it gives you... Total power ...

The power consumption will vary widely depending on the load and activity on the server, measuring it with a consumption device can be very misleading. The running costs will thus vary a lot depending on how you're using the servers. A servers's consumption will be below the rated wattage of the power supply, but you can't tell exactly how much under. If ...

I wouldn't recommend using that server today. The HP ProLiant DL585 G2 is a very old system (end-of-life: 2008). It is/was not a power efficient system. Power utilization for that platform was usually 400-600 Watts for a server loaded with 4 CPUs, a moderate amount of RAM and a full internal disk array. I know this from observation/measurement of old ...
