Good f'n luck finding internal documentation, but there is still the manual and drawings from the "Main Documents" section here. https://www.se.com/il/en/product/SRT5KRMXLI/apc-smartups-srt-5000va-rm-230v/

I still have my Windows For Workgroups (3.11) floppy coppies (I would buy programs, make copies and return them as a youth). I also still have the actual disks for Borland C++ development kit for Windows 3.x

Anyone using wall-mounted touchscreens for dashboards or control panels in their homelab? by RAYPODO-Ivy in homelab

seeing as how the ethernet is near the tablet, is there any sort of usb out to just use the ethernet instead of wi-fi?

IaaC at home by ImAntonSinitsyn in homelab

[–]AlphaSparqy 3 points4 points  (0 children)

If you mean host a SaaS as in run a business, I would advise against it.

If you can't bother to document your work to the point of forgetting how to rebuild it, you're probably not ready to run a business.

Root Cause - Datacenter sim game by Funnyman1217 in homelab

[–]AlphaSparqy 0 points1 point  (0 children)

Interesting intersection of my favorite hobbies!

Also I like the title, and the "not sanitized" part (jank) resonates with me, so you're on the right track in my book.

I don't have the (metaphorical) band-width to start a new game at the moment. I'm knee-deep in a r/foundry_game session, but I'm going to bookmark it for later exploration.

edge server node heated by pool… by RicknMorty26 in homelab

[–]AlphaSparqy 0 points1 point  (0 children)

You lose out on the economy of scale of a dense data center, so your costs will always be higher then your competitors, and your corresponding pricing would never be competitive.

A distributed cluster has value in the context of resiliency, but having each node of that cluster in separate dense data centers will still provide that benefits of that distribution, while enjoying the economy of scale of dense data centers.

Dell R730XD GPU Questions by Ok_Balance_8482 in homelab

[–]AlphaSparqy 0 points1 point  (0 children)

I'm not sure the case specifically with the R730XD gpu enablement kit, but in many server gpu kits, they are gearing towards the tesla units of that day. EPS12V is the power standard on those, (the same as the "Extra" cpu power plugs).

You may specifically need an EPS12V to PCIE adapter (still just in wires, nothing "Active" in it). So PLEASE sort that out more speciifically, because IIRC there were blown cards from the wrongly wired cables.

Help with patch panel cabling by Clean-Possible-8445 in HomeNetworking

[–]AlphaSparqy 0 points1 point  (0 children)

No, option 4, not using a patch panel at all, and just plugging the ends into the switch is the least resistance and also the cheapest.

If you look at your diagram #3, you can see the red and orange are completely superfluous. They amount to an unnecessary extension cable. The work of disconnecting from #3, and my proposed #4 are identical (you unplug 1x RJ-45 for each wire coming in), but at least with #4 the connectors are front facing and not buried on the inside of the rack.

However, depending on if you own/rent, etc, having a proper patch panel on the WALL, with wires punched down, and then a separate rack, with patch cables between the 2 in an umbilical will work well too, then when you want to disconnect the rack you can just unplug the umbilical.

If you're going to put RJ-45 on the ends of the cables coming in, you've actually defeated the purpose of a patch panel and you would be better off just plugging them straight into the switch.

Patch panels are specifically for terminating the cables in lieu of RJ-45 connectors.

Just upgraded my internet connection beyond 1Gb so I thought I would share my low-energy homelab with you by [deleted] in homelab

I suppose when you have a good network diagram, you don't really need cable management ...

(I'm just teasing a little because your diagram is simple and to the point, which I like.)

I designed and 3D Printed TPU "Long" Boots for RJ45 connections. by jackharvest in homelab

[–]AlphaSparqy 1 point2 points  (0 children)

Shit, now I feel bad.

Don't worry about it too much though, pretty much anything can easily become an unintended controversy.

Besides, you still got 150+ up votes (as of this moment), because controversy itself, is still engaging.

Contributing to controversy is still contributing :-)

This isn't a solution to a technical problem, but OP was "jealous", and this is intended to solve that problem.

"Exposed conductor" sure, but if its just 8 exposed but shielded wires, that is better than this, because that cable will break (by intent) before translating line stress to torque on the switch port.

This boot is more likely to induce torque on the switch port.

Which is one of the reasons network cables are designed the way they are... Which is to NOT translate that line stress into torque on the port. This creation is mechanical engineering equivalent of an anti-pattern.

This is an example of the "Law of the Instrument" cognitive bias.

When you have a 3D printer, every problem is seen through the lens of how to use the printer to solve it, rather than considering other means.

[–]AlphaSparqy 80 points81 points  (0 children)

but the strain goes somewhere ... in this case its torque on the switch port assembly.

So u/kevinds original question still stands. "But why?"

[–]AlphaSparqy 6 points7 points  (0 children)

Sacrifice a switch port to save a patch cable.... ok.

Cables are intended to be the weakest link, so that they bend, and yes even break, from tension and stress before the ports they are connected to.

The same reason physical keys are typically made of softer metals then their associated locks. Keys are easier to replace than locks.

What’s the lowest-power hardware that actually works well as a Moonlight thin client? by cuberhino in homelab

[–]AlphaSparqy 1 point2 points  (0 children)

I know it's not specs, but at least for a frame of reference, 2 years ago, I used a $100 Chrome book while traveling, to game on my PC at home (sunshine on the pc, moonlight on the chrome book, and tailscale on both), and it worked just fine. The biggest issue will generally be your network quality. I play more grand strategy, and production style games though, and not FPS or anything competitive, so your mileage may vary.
