Ok I am going crazy with all this UPS selection stuff and trying to figure out what all I need. I am building out a new server room and trying to upgrade some of the systems at the same time. I really could use some help thinking through all this.
Expected needs
Telco (switches and all other 2 post gear) - 2414 WATTS (pulled from APC sizing wizzard so likely worst case scenario)
Rack 1 - main production systems - 3761 Watts - Also pulled from APC
- Currently looking at the UPS it is using 2000-2200 watts
Rack 2 - secondary/test systems - 1400 Watts
- Currently using around 700 Watts
Desired outcome:
Have the systems running for around 10 minutes to allow the generator to kick on or gracefully shutdown. We don't really have much of a budget so price is a big factor in the final decisions. We are planning on setting up all the systems with 208V 1phase power.
Current thoughts:
- Get some Eaton UPSs for the Telco and Rack 1, repurpose a current UPS for Rack 2.
Now for some questions
- Would it be better to get 1 6KVA UPS to run Rack 1 or would it be smarter to get 2 3KVAs? We are currently using to 3 KVAs. Price would say the one UPS would be cheaper then 2 but is the loss of redundancy worth it? (Basically a 9PX6K with 1 EBM or 2 9130 RMs + 2 EBMs + 2 Management cards)
- I am thinking about getting a Eaton 9130RM with management card for the Telco rack - any better thoughts?
My next fun part is figuring out PDUs
- Do people normally just get 1 large (30+ receptical) PDU or 2 smaller ones? and why?
- Do you care about mixing brands with PDU and UPS?
Ok I guess I will let things stand at that for now. Let me know if you have any questions.
