VT units question

[BillP]

I've gone through the calculator function, to determine what kind of solution I need. Came out at just under 10k watts, and the three solutions offered were a Symmetra 12k, and 2 VT units. The Symmetra offered showed that we'd be at 99% max capacity, so I ruled that out. The others showed we'd be at 40% capacity. Anyway, I've looked at all the documentation I could find on the VT units, but couldn't figure out what else I'd need, in order to get the power to my servers. There was no mention of how to hook up PDUs, or whatever else I may be using to get the servers powered. Could someone please clear up my confusion for me?

Thanks,

Joe

The calculator recommended the SUVT30KF3B4S, with a 2 battery XR unit. As I mentioned in the original post, we will be sitting around 40% of max capacity of this device. I've since learned that the answer to my original question is that an electrician would be needed to hard wire the receptacles into the back of the unit, so that solves that question. However, I'm starting to wonder if this unit wouldn't be overkill for our server room. I haven't actually spoken with anyone in person yet, I like to do as much footwork ahead of time as possible first. I e-mailed the results of my configuration attempt to myself, and the link shows a total power usage of 9487 Watts, so I'm wondering if maybe a 20K unit would be better utilized, as we really don't have plans for any further expansion, as far as number of servers/devices that would need backup. Any future server purchases would be more for replacement, and not expansion.

Maybe a 40KVA UPS is overkill for your server room. You are really the best judge of that. If you have a 10KW load, the ISX20KF will give you 85% expansion capacity for power, and the ability to add racks and racks of runtime battery. This is a 3-phase UPS with N+1 capability at 20KW

The Symettra LX 16 kva scaleable to 16 kva will also fit the bill, giving you an equivalent level of N+1redundancy, but very little UPS expansion capacity. This is a single phase UPS.

Anything in the capacity range of your server room (10 KW) will require a hard wire input connection by an electrician.

It's time to talk to someone in person 🙂
