Do I understand UPS power correctly? in c/homelab@lemmy.ml

Yeah so that's kinda what I was getting at. If I put in three NUCs that pull 330 watts, that's 990 watts to the NUCs by itself. If the UPS can only provide 900 watts, then pulling more than that just wouldn't work right? The UPS would essentially discharge in seconds right?

I was looking at a ROG NUC like this one:

https://www.microcenter.com/product/683299/asus-rog-nuc-970-rn14srku9189aui-full-system-mini-pc_Hatchfeed

It states 330 watts under the power rating. And to be clear, this part of the build isn't going to happen for a while so I was just looking up some NUC examples. I was also looking at full 1U servers too.

But to the maximum ratings portion of your response. Even if 330 is the max, don't you want to base your predictions off of that to make sure it can handle things at max draw? Totally get that if you plan for less, chances are you won't ever hit 330 but you're banking on the possibility that you won't instead of planning for if you do?

Do I understand UPS power correctly? (lemmy.world)
 

Hey all,

Building out my lab, I was going to get a rackmount UPS. The one I'm looking at is a Cyberpower OR1500LCDRM1U. It says it offers:

1500 VA, 900 W, 120 V

Do I understand correctly that all I need to do is find the Wattage rating for each of the components I want to plug in and add them up? My components right now are pretty light, only about 120 watts total. But soon I'm going to expand and build out a Nutanix CE cluster with 3 nodes and a rack of drives. I was looking at using some NUCs but they are each rated at 330W.

So that would mean even the NUCs by themselves would over-provision the UPS right? Then on top of that I would still need all the other equipment in the rack to be powered.

Am I understanding this correctly or is there something I'm missing?

Choice between Cisco Catalyst 1200 and Cisco Business 220? in c/homelab@lemmy.ml
[–] ChocolateFrostedSugarBombs@lemmy.world 2 points 2 days ago

Yeah that's kinda where I'm coming down too. They both also do IPv6 Multicast which I'll use briefly later on when I start setting up the Nutanix CE section of the build but I mean...they look so similar I may as well save the $45.

Choice between Cisco Catalyst 1200 and Cisco Business 220? (lemmy.world)
 

Hey everyone,

I'm back with another question. I'm looking at switches and have it narrowed down to two options:

Cisco Catalyst 1200-24T-4X

Cisco Business CBS220-24T-4X

I'm going to have a Netgate as my main router in the house but I am also going to have a dev environment that I don't necessarily want interacting with my regular network. Originally I was thinking of just getting an unmanaged switch but I might like having some light VLAN capabilities of a managed switch that I can have the option of using.

I don't have any use right now for PoE devices so I don't need the switch to do that. I'm having a hard time figuring out exactly what the differences are between the CBS model and the Catalyst model.

It's a difference of about $45. As far as I can tell, the main benefit to the Catalyst is Cisco's Cloud dashboard. I don't need or want that. I'll handle everything through a VPN connection back to the house and honestly, I don't see myself needing to interface with the switch much after I get it set up. If the cloud dashboard is the only difference then I'll just save the $45 and get the CBS model.

But I wanted to ask you all if there's something else I'm missing that might make the Catalyst a better choice?

Thanks!--

What planning tool do you use? in c/homelab@lemmy.ml
[–] ChocolateFrostedSugarBombs@lemmy.world 2 points 5 days ago

Yeah for sure. I used to build much larger servers for my job so I'm trying to design for the future. I know I have some checkboxes that I need to hit now but I want to make sure there's room for growth/change.

Oh hey this is great! And FOSS which I always appreciate. Thanks!

What planning tool do you use? (lemmy.world)
 

Hey all,

I'm looking to build a small half rack server set in my house and was wondering if there were any tools that let me build out a solution? I'm worried I'm going to forget something and just wanted it all listed out as I think of things.

Yeah I can probably build it out and keep track of it in Obsidian or Excel or something, I was just curious if there were server builder tools like there are PC builder tools?

I mainly want to make sure I get a rack big enough for the few pieces I want to put in it as well as I want to try to calculate the power draw and BTU output which I imagine will be pretty minimal. I just would like hard numbers to know for sure.

Thanks!
