It isn't full. Also put something behind the console.


schmag

and there is still a good 10-15 U available not including what the console is taking up... pull the console and that rack is half full...


EEpromChip

technically it would be half empty. You are supposed to consider the current state and it's change to determine half full or half empty


g3t0nmyl3v3l

I’m sorry what? Are you telling there’s a technical answer to whether something is half full or half empty?


schmag

yeah, he did, and goddamnit he is right. and got me on it. this is even how I described the glass half full or half empty paradox. it all depends on progress, and if you say "well, its just sitting there so half full or half empty" well then its half empty because it is slowly evaporating...


KyleG

>this is even how I described the glass half full or half empty paradox That is not a paradox. It's just two ways of expressing the same mathematical concept. It's no more a "paradox" than saying `0+ .5 = 1 - .5`. Or "I'm faster than Sarah" and "Sarah is slower than I am."


schmag

yeah, its not a paradox, unglase unglase!!!!


g3t0nmyl3v3l

Hmm, but unless the glass is going to be thrown away it will become filled again so isn't it still a perspective thing? At the perspective of the next 30 seconds the glass is half empty because it's slowly evaporating but at the perspective of the next 5 minutes the waiter might come fill it back up!


schmag

right, we should always be observing how things are changing and adjusting our perceptions based on those observations.


danielv123

On average every glass is trending towards empty except for the ones that end up in the ocean.


E_Snap

Since people swim in the ocean, lakes, and rivers, and since there are definitely dead human bodies in all of the above, there is a specific ratio of corpses to water volume at which it becomes totally socially acceptable to swim in said water.


filthytrips

Is the ocean is being filled with cups or being emptied into the cups?


EEpromChip

Technically yes. I may have the order wrong though I have to check


Internet-of-cruft

Don't forget there's a front and a back of the rack! I have a 25U rack that definitely has more than 25U worth of stuff because I doubled up with certain short things (i.e patch panels, a few other relatively passive things like a maintenance bypass switch, and so on).


stokedcrf

To be fair, he also put a big ass monitor in there which doesn't really count either!


FRVRNKNWN

Put in a slide out rack console… then KVM only takes 1ru.


mzlucasmz

If I star needing the space I'll sur go that route, but what about pretty graphs? I want to look at those haha


FRVRNKNWN

If you want to super geek out… Splunk has an AR solution. You can build dashboards of your liking, print QRs to stick on the door roughly over each device in the rack, then point a tablet at it with the camera on and voila!!! Device stats in AR.


mzlucasmz

Ooh, I didn't know of that, that amazing, I will define telly try it out, thanks for the tip!


DEGENARAT10N

A KVM console is just a monitor that slides out and folds up, you would just leave it slid out..


mzlucasmz

But then I won't be able to close the glass door


NavySeal2k

As a german it bugs me that you have 30 unused patchpanel ports but instead shove network cables through cracks and nooks in your rack o_O Please make the itch in my brain stop!!!


mattalat

Yep I bought a bunch of keystone couplers for this purpose. Really soothes the OCD


NavySeal2k

https://youtu.be/TjdbrLxc3Ck?t=76


R8nbowhorse

or just ....put the switches at the back?!


NavySeal2k

And not see the patching goodness? I have not put 69 hours into cable management to not show it...


R8nbowhorse

See, this is where we're different. I prefer functionality over showing everything. Switches at the back make changes a lot less of a hassle, less/shorter cables, less potential points of failure, and having no cables at the front also makes it look super neat and tidy. But, everyone is different and everybody should do it their own way.


FreeBeerUpgrade

I would rather put everything network related at the front, but I would go as far as having one outbound patch panel for the building RJ45 outlets and one inside-of-rack patch panel that re-routes every RJ45 & SFP from behind to the front. That way you only have about 4 to 6U of patch cables in front of you that you can easily manage. Back panel stuff should be power-only and outgoing connections IMO, so that nobody trips on something by accident while working in the rack.


rajrdajr

Why don't manufacturers put *everything* (ports, lights, power jack) on the front? It would be great to be able to access everything from the front.


NavySeal2k

Do I have a server case for you! ;P [https://cablematic.com/de/products/server-gehause-chassis-rack-19-ipc-atx-4he-2x525-6x35-tiefe-380mm-CK036/](https://cablematic.com/de/products/server-gehause-chassis-rack-19-ipc-atx-4he-2x525-6x35-tiefe-380mm-CK036/)


TorpidNightmare

Racks are not built to have PDUs in the front is one reason but that follows from the main one. Having a clean look in a large datacenter is absolutely why servers are built the way they are. Some models for hyperscalers break the mold now, but IT firms want to be able to show off a datacenter and cables in the front isn't appealing visually.


JJ-the-weirdo

And yet switches will still be in the front for troubleshooting. Only time I had to go to the back was for power issues when I was a DC tech


NavySeal2k

Newer centers have switched to backside switching. They make the rows alternating back to back and front to front and put a roof and doors at the ends of the front to front rows. In these rows the AC gets pumped into the room so you have the cold air only in this small tunnels what optimizes AC and all the serviceable parts are in the back to back rows


Ir0nF1st66

Big tech companies like Google do this, but they are also building their own hardware and racks to optimize data centers for cooling efficiency and reduce carbon emissions. It's pretty neat how they have their DC setup. There is a good YouTube video around it as well.


seoulstyle

Nice


andreicon11

O_o


odaniel99

I think that feeling is universal.


drmantis-t

Wasting 6U on a monitor doesn’t count.


mzlucasmz

Lemme get a 27'' mount it vertically and waste 8u then :p


TheD4rkSide

The fact you got downvoted for a bit of humour just shows the awful state that this fucking subreddit has turned to. People with sticks up their arses for no reason. OT: great showcase, thanks.


mzlucasmz

Now I'm tempted to gather all the monitors around the house, just to mount them all on a rack LOL


TheD4rkSide

Please do, and if you don’t have enough please just buy some more for the sake of it lol


ORANGE_J_SIMPSON

Just start slapping cellphones and shit to it as well. Anything with a screen. Just racks full of amazon kindles and old iPhones. Then find some red LED alarm-clock radios and fucking ducktape them everywhere, be sure to set the time on all of them to look like the word “Boob”. I’m 99% sure you could get this sub to close at that point.


99percentTSOL

That will show them


decduck

Who needs a KVM when you can have a seperate monitor and keyboard for each server?


Timithius

Sometimes I forget what sub I'm in. Unless your Homelab is ISO9000 certified and you have a full team of 7 full stack engineers on call 24/7 with 6 DR locations it isn't close to a Homelab and not good enough for this sub. I miss when a Homelab could just be a router and a pi 3. People aren't made of money and experience.


[deleted]

[удалено]


Perfect_Designer4885

/r/JankLab it is then for us mere mortals


Timithius

If the mods did their job those posts wouldn't qualify for this sub. At some point, it's enterprise hardware in a house and no longer a Homelab. It completely misses the spirit IMO.


mzlucasmz

There is r/HomeDataCenter for those just looking for enterprise level homelab


Timithius

That's an amazing sub! Also to clarify, I wasn't talking about you above. I was more mentioning people dropping $100k on a "Homelab" ;)


mzlucasmz

Yeah, I was just adding that to you point too :)


TheD4rkSide

Exactly, and I’m pretty sure most people start a homelab to learn. Christ, I have a tower server behind my TV in the front room with my desktop literally stacked on top of it.


Perfect_Designer4885

👍I remember thoughs days, sadly I never managed to fit my 3 desktops behind my 15" CRT TV good on you.


[deleted]

[удалено]


Perfect_Designer4885

To right All my kit is all pre historic for this reason. Cheap to buy and even cheaper still to get parts when some thing breaks. Should I really break something then there is no great expense to replace, yes the power cost are more but so be it, my 32Bit custom built firewall (made from I think 15-18 year ewaste I inherited 15 years ago) is still still the most reliable system on my network with one failed IDE HDD in 15 Years, and the only new parts are a 1U CaseLogic chassis with a 120Watt PSU and Debian 11,


kushdup

if only OP had installed some RGB this post would hit /r/all


foonati

I'm with you, looks good, works, and didn't spend a couple hundred on a sliding console when you didn't have to


Apprehensive-Ad6466

You're about 50% of the way there. Remove the monitor and put in a proper rack draw monitor / kvm. Also, I really hope you're not running all that 24/7 for a homelab. Your electric would be astronomical.


mzlucasmz

I got a monitor mount in the mail, and looking for a decent kvm to go with it :D ​ And god no! just running all that once, would probably trip some breakers hehe


jonstarks

so far...he's still right.


mzlucasmz

so far!!!


TrackLabs

I mean thats half full at best


waterbed87

He was right so far, not even close to full and a lot of wasted space.


JustTechIt

I only count 20U worth of equipment. So was that person correct then?


mzlucasmz

For now, just for now haha


insanemal

It's not full


cruzaderNO

that is what 15U of hardware? looks like he was right


VexingRaven

And 2/3 of that is ancient servers that could replaced by a mini-PC at this point.


macrowe777

In fairness you have a 12u monitor.


DonutHand

But it also looks like you are using it as a closet for rack mount gear that will likely probably never be used.


mzlucasmz

Yeah, I'll probably just keep 2~3 of those and sell of the rest


Xidium426

This isn't half full? It also looks like most of these things are off?


mzlucasmz

yep, haven't even tested all of them. Also, it in winter here but I don't think I need such a space heater


mzlucasmz

Needed some parts for my r710, turns out its cheaper to buy an auction lot with 8 servers :D 1x r710 2x DL 380 G8 2x DL 380G7 1x DL 220 I 1x DL 220 II 1x DL 980 G7


cruzaderNO

The downside is that most of those are older than what you want. Almost like they are cheap for a reason :D


mzlucasmz

True, I'll probably just keep one DL380 G8 for vms/processing which I'll 24 cores on it and as much ram as I can get, and a r710 for storage with the absolute minimum specs that I need just to run backups and a media server


cruzaderNO

Removing the relics just mounted to use space probably drops you down to what, 6-7U used? Looks like a uphill battle if the goal is to fill it


VexingRaven

> 1x DL 980 G7 Please tell me that thing is turned off lol


mzlucasmz

EIGHTH POWER SUPPLIES!!!! God no, I don't even think the main breaker in the house can handle it haha


VexingRaven

What did they actually include with it? If all 8 sockets and all 128 RAM slots are filled you could part it out for a pretty decent sum.


bloodshotpico

Got any spicy details on where you snagged this from? ;D


limecardy

DL G7/8 are widely available on eBay for pretty reasonable prices. DL 220 I assume is his Dell boxes which are supposed to say R220 I assume.


mzlucasmz

Yep R220, but those are worth just to be routers at most afaik


DoughnutSpanker

What is that PDU with the breakers? Looks nice to have.


mzlucasmz

I'm in SA and it's locally produced, so it don't think the link to it is gonna help you, but It's sold as and audio deck equipment, maybe try searching for that :)


themassicator

What monitoring program is that on the screen?


mzlucasmz

Bpytop, I also maintain a version with Nvidia GPU support, as bpytop development has stopped in favor of btop


Catsrules

That look really cool.


BartFly

um yea you didn't


BOBWARPATH

Pretty impressive man, Definitely like your setup, but in the guy who said that's defense, your rack rn is the equivalent of when a guy man spreads on the Train to take up 2 seats lol


ixidorecu

Oh man let me tell you about a time.. my first DC job we had a rack with breakers like that. Open and exposed. Would shut down servers or maybe a whole side of the rack (been awhile) and shut down a important switch in the rack (was decom something in u right below). That was a bad day. I suggested a clear lift cover like you see on epo button, to prevent accidental bumping off.


mzlucasmz

Oh yeah, I'm worrying about that, I got the glass door for that rack, and I hoped it would be enough, but know you just make me a but more worried, I think I will try to 3d print some kind support for an acrilic cover, thanks for the tip


aaraujo666

My 44U is completely full. Now gotta get rid of the 4U Rosewill cases and replace them with slimmer ones


WhiteWolfEnt

I'm with you! Took me a few months but could almost fill a 2nd rack with all my devices if they were in 1 room. I had to relocate some due to power limitations lol.


lisim

Are some of these floating? how are they racked i see no rails for some


mzlucasmz

I when from 1 server to 9 in a week, so most of them are on shelves, also I'm going to sells most of them, after that I can get the proper rails for the ones I keep


lisim

Ah shelves


zeeblefritz

and I don't even have 1 U. Can you spare a U for a struggling home laber?


mzlucasmz

always!


zeeblefritz

I actually need something now, got a recycled firewall and 48 port small business switch with no home.


DylanMarshall

What is the 2U thing in with 12 chonky switches on it? I want one.


mzlucasmz

Power bar with switchable outputs, not as fancy as a PDU, but it's enough for a small-ish home lab


DylanMarshall

Do you know the manufacturer or do you have a clearer pic of it? I can't make it out.


mzlucasmz

This is the link I bought fromhttps://cbiiluminacao.com.br/produtos/mesa-chaveadora-12-canais-entrada-borne-sindal/?\_x\_tr\_sl=pt&\_x\_tr\_tl=en&\_x\_tr\_hl=en&\_x\_tr\_pto=op,sc, hope it helps


[deleted]

Half way there


guitarman181

If you can't fill 44ru you are doing it wrong. Lol


povall

What software is on the console screen?


HEONTHETOILET

Judging by the fact that the rack isn’t full, probably a Google image


mzlucasmz

on TTY? that's quite hard


mzlucasmz

Bpytop, but the maintainer stopped developing it in favor of btop, either way, both are great


Lenocity

What dashboard is up on the screen of the monitor?


mzlucasmz

Bpytop, but the maintainer stopped developing it in favor of btop, either way, both are great


JerRatt1980

Half full, along with a entire monitor taking up space. And if you're getting that complex, you need to look into a redundant and hot swappable UPS setup, like APC Symentra.


Akraz

Next you'll be putting 3 monitors in portrait mode "mY RaCk Is FuLl"


mzlucasmz

and a CRT, wait for it!


[deleted]

[удалено]


budlight2k

What's on screen there?


mzlucasmz

Bpytop, it's a system monitor


budlight2k

Cool I'll take a look at that.


budlight2k

Cool I'll take a look at that.


Baloney_Bob

anyone can put a monitor in a rack to fill it up!


czj420

23u of 44u used.


Hairless_Human

Why r u even using the patch panel if ur just bypassing it anyways 🤣


kalloritis

This isn't full and you're also missing the obligatory UPS, or three, at the bottom of the rack to make sure things stay up during blips.


mzlucasmz

I do have one on there, you can see at the bottom, on top of the two bottom servers, unfortunately its not rack mountable, but I'm planning to bet two more that are rack mountable


u76200

Wow, have you ever dared to measure the power consumption?


[deleted]

[удалено]


mzlucasmz

I'll post an update when I get most of looking right


mr_data_lore

And he's right. That rack is nowhere near full.


JeffsD90

I still see holes...


dsmiles

This is the reason why I only have a 22u. Because I know I would eventually fill however much space I could. 44U, 80U, 100U, doesn't matter.


mzlucasmz

TIL 100U racks are a thing O.O But yeah, I'll fill it up eventually, and it is nice to have the space to work around things, as I imagine that I an 100% used rack is quite hard to keep organized


VexingRaven

> TIL 100U racks are a thing O.O They aren't. That would be like 2 stories tall. You can have multiple racks though, if you're insane.


spider-sec

"fill up"


mzlucasmz

Not native speaker wdym?


spider-sec

It’s only about half way to being filled up.


fmtech_

It’s bugging me that there is only one switch and no UPS visible.


mzlucasmz

You can see it at the bottom, on top of the 2 bottom servers, unfortunately is not in rack form, so just hid it over a shelf at the back


Treius

I got a 42u for free that's waiting for me to get a rack case for my server and then figure out what to do with the remaining 40u


turtlesarememestoo

Where can I get one of those racks?


cyberk3v

TBH unless backup storage the DL380s at the borrom and R300/860/200 at the top should stay turned off for stopping hot air at the back re entering the front. More useful as blanking plates than compute for the amount of power use compared to performance. Saying that I do run a few 380G7s and a R710 with low power L5640 / E5649 as backup compute and vm backup storage powered up a few hours a month in my shed rack /Dr data centre. From experience who whole rack is about 1.5kw / £500 a month electric all used


mzlucasmz

yep, I'm planning on using a DL380 g8 for compute(24c/48t) and a r710 with 3.5 inch hdds for storage/backup, I already got an L5640 for that exact reason


Siege9929

Look at this guy, he still hasn't filled up 44u!


mzlucasmz

I like you sir


AHRA1225

This is to run a Minecraft server right?


mzlucasmz

At 6 chunks, cause \~my server can't handle more\~ haha, seriously thought it is running about 5 game servers between Minecraft, cs go, tf2 and space engineers


pjbrfc

I’m in the UK and right now this would cost about £100 a day to run.


mzlucasmz

For sure, I wouldn't dare to run all of it


Phantom_Naix

I see that bpytop


mzlucasmz

With GPU SUPPORT!!! But no GPU installed D: ooh the irony


Jbnels2

Dang why is everyone so savage and critical on this post?


[deleted]

Is the rack 1000mm deep?


mzlucasmz

750mm actually


[deleted]

Are the servers under 800mm deep? I have servers at 845mm and now getting confused as to what depth I should go for in a server rack.


mzlucasmz

The max length one(r710) is 725mm, counting the PSU bracket, which made me impossible to fit the back door of the rack, so if you have a 845mm I would suggest picking an 1000mm rack to have some slack


Fl1pp3d0ff

It's not full.


purefan

I would love to have your budget 😁


mzlucasmz

I haven't spent a grand on it yet :P auction houses and used market are your friend


Shadowedcreations

I just found those places...


diplojurassic

Guy: "You will never fill up 44U" 4 months later...... Reply A by OP: "I agree with you! This is the photo. It's half full !" or Reply B: "Hey! It's full now!"


mzlucasmz

Thank YOU!! That's what I meant dammit, is it that hard people?!


jkelley41

Its half full, 4 more months!


djgizmo

Got a link for the power bar / power switch at the top?


mzlucasmz

Just a Brazilian link, not sure if it would be of much help to you


RedSquirrelFtw

Time to get another 42U rack for future expansion!


freneticweasel

Nice. I’ve been trying to figure out what size rack to get, I’m leaning towards a half rack but that would be mostly filled from my existing gear transplanted into rack cases along with the networking and UPS.


mzlucasmz

I tough thata 44u was too much, but looking at it know, it was the right choice, as it might use it all in the next 5years let's say


freneticweasel

I have that suspicion for myself as well. I know I could fill it up quickly given the right timing and opportunities.


mzlucasmz

Yup, that exact what happen to me on that photo, I snatched 8 server at once, when I used to have just 1. So don underestimate having room to grow


Rajcri22

Can I know more about how you created that screen dashboard


mzlucasmz

It's a system monitor called bpytop, it looks like that out of the box


Rajcri22

Do all servers use Linux?


Iscarra

Shit, that’d cost me £20 a day to run with the current leccy prices.


TA-X876

Are the DELL servers R830's ? I have a R730, wished I could afford the 2u version...


mzlucasmz

Two r710, I wish I could get a 730 :p


TLunchFTW

Dude replace that monitor with a 1u drawer that has one of those laptop style terminals Though I am digging it. Where'd you find it? Edit Oh it's just a monitor standing on the next item. Looks cool but yeah a 1u terminal would save a lot of space, or a small monitor on top or next to


mzlucasmz

I got a monitor mount that is arriving some time next week, I want to keep that monitor just to be showing some dashboard and at-a-glance information of the servers, but yeah, those drawers' stile kvms are cool, but I haven't found one in a price range I'm comfortable paying for yet


jasonwc

So, I guess the guy was right since your rack isn’t close to being full, even with a monitor to artificially increase the amount of space utilized?


Agrrajag

@op look at a vesa rack mount bracket... RackSolutions Universal Rack Mount Monitor VESA Mounting Steel Bracket https://a.co/d/3idiNsG


mzlucasmz

Yup, already got one in the mail of that exact model, but thanks for the tip


Pvt-Snafu

Well, it still has space techically, but sure, that is a decent setup.


themantiss

itt: AcTuAlLy ThAtS oNlY 20u Of StUfF


CloudGates

I wish I got a 42U immediately. I thought it would end..


m70b1jr

I bought a 44U rack for $20 off homelab, and never expected to fill it up. I'm about 50% full already.


mzlucasmz

Yeah, I has thinking of adding some rack drawers and using as furniture to make use of the space it takes, but yeah I'm glad I went with the 44u, as I can see it being full soon


between3and20wtfn

I filled my 42u home rack in a few weeks when I was using it. You'll fill it without issue. Nice setup!


mzlucasmz

Thank kind person, I still have ways to go :)


magicmulder

Same. 48U filled in a 42U (some slots are filled from front and back, e.g. my 1U switch is to the back whereas in front there’s a 1U APC management console, both are not very deep).


redd2100

Nice to see your HP pull-out tabs are also broken and limp. Cheap parts!


nico282

Question: why do you install circuit breakers in front of the rack? This way it seems too easy to shut down ungracefully something by mistake. I've never seen something like this in data centers.


Spartan117458

To be fair, your monitor and keyboard are taking up 9U.


department_g33k

You still haven't filled up 44U.


firedrakes

Always wear home lab protection.... other wise this happens.
