The Keyword here is ATS or Automatic Transfer Switch.
Those usually get used in the Datacenter where you switch between Generator Power to Powergrid and back.
They are available in different sizes. Small ones from APC that can do 230v at 20A Or bigger contraptions which take a moment to switch over to not have both inputs on the output (and connected together)
Lol that same bill would slap me with a 1.3kEuro/A bill lol at 40ct/kwh
I am paying the same 270 for my 60W lab.
Great talking points tho. Power is always somethign to considder whenever I see someone getting a big enterprise server.
Further be aware that PCIe devices also need to support sleepstates. So if you add an old enterprise card liek 10g to your server/machine, then you might idle at twice or more times the power it would otherwise do as that device prevents lower sleepstates.
so the cheapest 10g card or hba is not the best in the long run
Experience. But it all depends. TDP gives a hint in some generations example epyc cpus TDP is relaivly acurate wheras the 35w tdp of intel second gen means litteraly anything between 10 and 60w.
But for consumer systems with an i or r5 cpu and a mid tier gpu 500w is enough. For a server without a gpu and similar cpu 300W will suffice.
dual socket systems of that cpu class maybe 400-500.
With more enterprise stuff 500-700 or with epyc maybe encroaching 1000w with some addin cards.
It depends on maany other variables like Drives attached, PCIe devices used etc.
Soo you are saying you draw a random ass conclusion from an issue which would not exist if you would have made the right hardware choise? got it. Well done.
It all depends. First you dont have to get your own hardware. Sure some of us get stuff from work for free or have an old PC but even a 100 Buck PC is 5 Months with linode for example. Secondly, Linode is not the only option for example Netcup offers a VPS with 4c 16gb for 10-15 a month. So that seems a bit more fair IMO.
ANd theres other reasons. Like: You want to selfhost. But don’t get a public IP. Or your internet service being so bad that its not worth it. Which are all issues you don’t have with a VPS. Further Uptime. At home to keep a good uptime you would probably want to invest in a UPS and other hardware to eliviate problems. which further costs money which you could invest into a VPS.
And the Killer for me is Power Consumption. At 40-50ct/kwh running a PC of 60w costs me 300+ a Year, whereas a VPS at 15-20 costs me 240. And I get the benefit of lower latency and better bandwith and not needing to pay for extra Internet service.
So it depends. I do still selfhost stuff at home, why? not because Its cheaper, it actually isn’t but rather to gain experience with the hardware etc. But i do see that many people may not want to deal with that. So a VPS is defo a viable option.
My advice if you don’t want your house burning down. Dont fiddle with it, thow it away, or make an RMA claim.
It not like its a 100 Buck product. Saftey goes first here.
I monitor/log it with a smart plug, or UPS.
At my home I have a shelly plug s Which is just a wallplug insert. That monitors consumption and can give it to you via MQTT, I port it to home assistant and monitor it. Usually my small HP mini node with a couple switches and Router is about 80w.
At my parrents I have a Shelly 1PM Plus, which is integrated in the path to the UPS. It monitores everything like the PoE Switch APs, Server etc as everything is connected to it thats IT. Its about 4.5kwh/day so about 220-240W. That gets also monitored via Home Assistant and MQTT. and 4.5khw/d are bout 2.5USD/day for me. So about 920USD/Year.
So Defo more expensive than a VPS would be. But also more custom and more of an Experience to gather.
SAS is not networking. If you expect to connect 2 systems to another it wont work.
If its just for disks then yes.
