Looking forward to the next one.
Good to have you all back, another interesting video guys, well done and stay safe !
The boys are back.
Guys, thanks a lot for the content, for sharing experience! Watch you for development of my it skills and english language also! Hello from Russia, Saint-Petersburg!!!🖐
Awesome! I am currently learning STP, this is so helpful! Great job, lads. Thank you.
Awesome 😎 as always guys! Keep them coming! 👍💯🎯
Happy to see you back, guys! Looking forward for new videos again.
Stay safe.
Great video as always, thanks guys!
Can't wait for part 2!
Ye, I love these videos really interesting, glad to see your all safe
Super cool and interesting video. Thank you !!!!
Thank you guys for such a wonderful Video.
Thank you for making these videos!
this video series looks really interesting. can't wait to the next video.
Amazing videos. I am about to go to an interview for DCops and so glad these kinds of videos exist on youtube.
Amazing. Thanks for the video. Greetings from Portugal :)
Hey guys, loving your videos and waiting for the next to watch :)
nice explanation guys
Infinite awesomeness Custodians!
I M excited to see next video
Great video, really looking forward for part 2, keep up the great work guys, I'm just starting out in networking and I love your videos, they really help out a lot.
At last reached ma place... Subscribed and you pplz are really sharing knowledge which is very useful for many ppls like me thanks broo
Excellent Video. Thank you! So one of the switch will be primary and the second will be the failover.
Hopefully more networking tips/tutorials!
100% uptime... Can't get better than that 👌🏼
100% uptime on every switch port - liars then.... or never patch the OS.... or plan DR tests
Good work guys
Amazing! 😎👌🏻
Awesome stuff
quality video ❤️
Ayy, good to see you guys are back. Can't wait to see plenty more from Custodian in the future
STP works pretty much trouble free. Shutting unused switch ports is a nice little tidy detail. I'm going to start doing that, and recommending that my students do so as well.
Great! thanks.
very very nice.... :)
Ahaha that noise of rubbing hand sanetizer eh! ;) lmao.
Loving these vids, just about to go study my MSc Advanced Computer Networks degree alongside CCNP Woop Woop! :D
That's some serious eol gear guys 😉
That's why it's in a demo.
Waiting for the next video
Love the video. this is the kind of job i wana get when i get my ccna.
just work for a proper datacentre who have standards!
Love from PH🇵🇭
The switch ports are facing rack back door, it meant they are port exhaust air? If not the hot air will goes to cold isle which will waste cooling power.
The Cisco 2960G should be single power feed only, the better practice is install STS/ATS and connect the power to it so to have redundancy power supply.
Looking forward the port vlan setup, the port shut down default is really good tips, thanks
Have you investigated on moving to a new leaf-span setup when it comes to networking? Like with Nexus equipment or similar?
YAAASS A NEW VIDEO!! Just in time cause I'm studying for my CCNA too
another packet tracer junkie!
@@TunaNSweetcorn is that bad? Lol I'm relatively new to networking (just recently got the net+) and packet tracker was suggested by NetworkChuck. Unfortunately I have no equipment at home to experiment on. So far it's been cool, but its the only program like that I know of.
I wish such a program would work in the real world. My consumer grade hardware only works 65% of the time and only has 2 configuration options.
@@chrissanchez3884 im the same, just starting on ccna studies. There is GNS3 as well but packet tracer is enough
@@TunaNSweetcorn Ok I did some googling and it looks like GNS3 actually virtualizes the IOS running on the switches/routers; where Packet Tracer just simulates it.
I think Packet Tracer should work fine for my level. The labs that come with the official cert guide are nice too. I might give GNS3 a try though as I get deeper into my studies.
I like these guys and their videos, though surely in modern datacentres copper drops from above is old-school. All the ones i've been in for connectivity (unless customer racks are directly next to one another) require the customer to request a ToR FOBOT that has SM fibre to diverse x-connect / meetme rooms where the rack-to-carrier or rack-to-rack x-connects occur.
i like how RTX Voice can remove all the servers fan noises of your videos :D
Which pdu are you using?
It looks really cool!!!
I miss working on networks😭 I can't wait to switch roles.
Just curious. Is there an advantage for having several smaller pods vs large pods encompassing everything? Is it easier to locate cabinets? Thanks.
Could be a security advantage right.
It looks like they use at least 25kw just to keep the doors shut.
if you can put some topology diagrams on the next videos for more understanding will be great.
Why use a full 48 port switch. Wouldnt it be more economical to use switch with fewer ports. Or would that be shared among other servers as well in the rack?
Probably easier and cheaper just to stock 48 port ones. And if you have 24-port and need more later...
This looks like it is the data center closet and those ports would feed out to the other racks in that row so those switches may only feed 12 racks, maybe less. The customer may also need part of their backbone to carry MPLS or whatever so those 2 switches may only actually provide redundant connectivity to a handful of customers.
Longtime 😊
Hi guys, I have a question. It might be a stupid question but I'm really curious. Why do server uses copper cable instead of fibre optic? Isn't fibre optic are better ?
In my opinion PoE
guys I want to start my own data center you aroused my passion thanks seriously
just don't follow these guys.
Do you guys use juniper?
Modern day phone guys.
Is that an open reach avda switch in the top of that rack?
Doesn't look like it, has the wrong connections, only saying that because ive installed about 1000 of them
@@xer0334 think your right. It's defo avda but supplied by openreach no.
STP is used for loop prevention ... i think you mean HSRP? correct me if i'm wrong please
Loop prevention in a redundant switch network. Why would you have redundant switches? For redundancy 😊
HSRP is configured @ the router
I get what you're saying. HSRP is a protocol for providing a backup router. Whereas STP prevents switching loops. If I had to name a "router version" of STP, it would probably be Split Horizon.
what was thepurpose of the two short blue cable connected to the switches?
You can stack the switches and maintain them as a single unit. This is what I think they are doing when they connect the switches. Enlighten me, when I´m wrong.
@@hergerlodbrok559 mate listen that is NOT STACK....you have two type of STACK whit card+cables or Virtual what u did is just connect two switches
The switches otherwise can’t communicate between each other.
Me with one pfsense box and a single 8 port vlan: OK guess that's a bit bigger
*click* Noice
Always screw in the bottom first ;-)
I cant catch why you guys has to config the software of this switches of those switches, belongs to the costumer,
not the costumer itself has to config the ports of this switches via software?
They didn't explain what the blue cables were doing at the end of the video
I assume they are up-link between two switches and configure as LAG for intercommunication and fail-over.
@@pluanant correct.
Trunks, I guess!
“Cheap.” Don’t lie to me. We both know “cheap” is very much relative here.
It's all damnlies innit?
@@papie7627 Nah, that's statistics.
You guys work two people per shift? The Dc look no too big
@@kruemmelspalter800 o yes haha
Interesting your only using cisco far as I can see
USE ASR 9K AND PA 7050 SERIOUS
gladly be yours all-time
I see blue cabels. what are they used for? iLO?
I guess those are the failover cables. So when one of the red/green links go down the switches still have internet access. What I do not get is why two cables are sufficient. Unless those two cables have a much higher bandwith, I'd expect to see much more failover cables.
2 blue are combined together to make 2gbps link between each switch
Link aggregation (LAG) (Etherchannel) for failover and it will double the link speed.
Why the 2link cables between switches?
You can configure them as a LAG (Link aggregation group). This means a port can fail and you still have the interconnect between the switches.
They're probably trunk.
Is that cat 7 ?
I think Facebook did the opposite 😂
Didn't 2960 go end of life a long time ago?
What's your point? It's an educational TH-cam video they're doing in their own private test rack with some old gear.
@@ItzD3fW1sH I'm asking if 2960 went EOL a long time ago because I don't recall offhand.
@@29outlaw yes but for a tutorial who cares?
I run python scripts to back up our switches can We ask where you use thanks 👍👍👍
Etherchannel.
machines ray baba
Don't you mean VRRP instead of Spanning Tree?
VRRP is when 2 routers connect to 1 switch. In their case, they have 2 switches with 2 seperate connections. They then interconnect them with port channels that need to be configured to prevent spanning tree problems. Each application server will then get a line from Switch A and a line from Switch B
1:28 what is meaning green vs red cable?
@4:40
I want to be a part of you guys. Even if u give me job of entry level. For me it will be an honor.
Your man has his mask on the wrong way down
I promise to I am 🔙 to u forever having a great time in DC for fall in love automatically yes love😍
voice is very low
psh 1Gig switch...
I mean its a demo with old switches
Please post game server for (eg) free fire game server
once again, i know why custodian would never touch my corporate network.
Explain please
man don't leave us like that explain to us what they did wrong so we can learn I am a newbie to this and I don't understand 50% of what they are saying
@@marouanebenderradji137 1) Old Kit 2) old Stacking methods 3) cable bend radius 4) ethernet cabling standards 5) close proximity of data to power 6) Cable ties on cables 7) overtight cable ties
seriously,??? You seem like a top rated DC in UK and you are using Cisco 2960G that is EOL and 5+ years old? I expected top of the line Cisco switches, not some lab switches that costs like 60-100 dollars. I know its gigabit and all, but still. The port shutdown is default at any cisco switches that you can get into CLI. I really hope and expect top notch security configurations since I assume you both are atleast CCNA certified.
I feel like you don't know what you're talking about. You can bring CCNA into it all you want, it really isn't difficult to get a CCNA these days. The start of the video they explained that the rack is their own. We have Catalyst switches laying around for us to test on and play around with. This is a "tutorial", not a full customer installation...
@@adam9041 You are absolutely right, its my own stupidity for thinking like this. I couldnt find where they said that rack is their own,but I should have thought about that because that rack they are doing is a little to empty for a customer rack. I'm sorry for bashing the Custodian DC and thanks for correcting me.
@@andersgjerlw9636 1:02
@@adam9041 if its a tutorial saying HOW to do things, that makes it even worse!
Wow... if I couldn't hear you over the fans before, its damn near impossible to hear you over them now with the masks on. You practically have to scream to be picked up by the microphone.
Turn your volume up

Using STP as your fail-over mechanism???
The 00s called, the want their tech back
Terrible choice in switches for a DC
I'm all for teaching people on TH-cam but your channel seems textbook "how not to do a DC"
I'm not going to stalk you, this will be my final comment on your channel
I think it's their own test racks for testing and miscs
well said!
I agree, should not be implemented in 2020, Nexus should be what they use, as a data center if they were to use nexus equipment it would be much more beneficial
@@ReissJerham exactly. Hence why custodian will never get anywhere near my networks
It's clearly their own test rack, with old random gear they had lying around in store to create an educational TH-cam video. Your comment just makes you look like a twat.
What kind of credible business are these people trying to run.? This is like 2 guys in a shed! I wouldn't touch the company.
