I have a small server rack with 2 x HP Microservers, network switches, and an upcoming/planning Hikvision NVR. Would like a UPS to give better power supply reliability. Looking for recommendations please. Should I look into the pure sine wave ones? Which brand/model to go for (apart from APC).
Thanks
Thanks. This is just a small home server rack. Not a commercial setup.
I currently use Cyborg UPS, Pretty cheap around $200 - $300 depending on how many watts you want. There's also a com port so that you can configure it to do anything if the power runs out.
Thanks. I googled cyborg UPS and all I get are pictures of cyborg in justice league. I assumed you mean cyberpower UPS?
Did you get the true sine wave one?
Yeah cyber power sorry, got confused with a keyboard brand. I have the older version but the new one should do the trick. Were you planning to use c-13 plugs or normal?
I already have a server rack PDU with normal australian standard power sockets. So would like to plug this PDU into the UPS so the entire PDU is under UPS backup.
I managed to find someone selling new Eaton pure sine wave 1000va UPSes on eBay for ridiculously cheap prices at auction quite recently. It seems they had a heap to sell. Would recommend.
Found it - was an Easton 5SC1000i for $182 delivered. It seems that there are still more of the same model going much cheaper on eBay even today. Stores sell 1000VA true sine wave, line interactive UPSes for much more than this.
Thanks mate. I also found it thanks to you.
Not trying to discourage anyone from getting a UPS, but I don't have a UPS for my home server because
Linux filesystems are quite resilient to unclean unmounting and will be fixed up next boot. You may lose a file you are working on. As for the rest, I have backups.
If the power goes, so does the broadband connection, and the lights in fact so I just go to sleep or amuse myself listening to music on a portable player.
Adding a UPS creates more losses in the power supply chain. Also there is capital cost.
Supply is quite good in the my metro area, perhaps one or two power outs a year.
Of course if you are in an area where voltage fluctuates, is subject to spikes or you need to keep cameras running then a UPS is needed.
I am interested in a UPS purely to keep my router and switch from suffering potential cumulative flash storage degradation when the power dies (which happens more often than I would like). I'm happy to have my opinion changed if anyone thinks I'm wasting my money, though…
How many cycles are flash storage rated for and how many power cycles will you suffer over the lifetime of the equipment?
for SOHO use, a line interactive is all that is needed. Your PSUs are not subject to any sine wave disruption, and your devices are unlikely to have a inbuilt UPS themselves. (had to have daisy chained UPS for work reasons in the past!)
Be aware that in SOHO use, a UPS is more likely to completely discharge due to being unable to turn off some items. The UPS will not turn back on power until it reaches a minimum charge (configurable)
A UPS for those annoying 30 sec drops is great. Power companies are getting better at preventing sustained brownouts (it drops instead!) and over voltage is only is some areas (industrial/ex industrial)
Your internet being up or down depends on the technology used. Like many things, the cheap to install, but expensive to operate technologies just fail with power outages. The Slightly more expensive to install, but cheaper to operate technology will keep working for a few days.
Powerware, Eaton, Cyperpower are all good brands. You want at least a USB port for the option to configure and run some management. Don't go over 1500VA. You are better off getting an UPS with additional battery at that stage.
Do not connect your laser printer, but would highly recommend connecting your 3D printer if you have one.
650VA. good for single PC+1-2 network devices.
300VA - Good for TV
Not directly answering your question. But think about moving your infrastructure to AWS or GC or Azure.
