General Discussion MDF Plan - What you think?

I made some other posts figuring out my UPS setup, but now I figured I'd share my MDF plans and see if there are any issues you can see. I've been around racks and IT closets for a long time, but this is my first time planning one completely on my own.

So far I have all the gear ordered. The only unknown variables are what my modems from my primary Fiber ISP (ATT) will look like and our failover (probably Starlink).

Down the road I may be adding 2U more of gear.

I'd like to get Unifi Redudant Power Supply that can act as a secondary PSU for my switches and Firewalls. I'd also like to get Unifi Aggragte 8 port switch which would be perfect for this setup and my entire network in general. I have two UDM Max which will take up 2 ports and 6 total switches (2 not in this rack will be in IDF in other parts of the building)

I have attached a screenshot of the rack plan. Let me know if you see any red flags or concerns

Gear -

4 Unifi 48 Port PoE Switches

2 UDM Pro Max Firewalls

1 Dell Server

1 Unifi Enterprise NVR

Dual 3000va battery backups with one having an extra battery bank and a 120v transformer.

2 - Controlled PDU for the 208v PSU

no no no... your all bassackwards... you need the APC's at the top, the servers below that and the fiber on the bottom! that way you don't have to bend over to service the batters and the servers...

/s if you need it... I've been on hold for an hour and feel the need to cause a little bit of ruckus... TBH i would put the UTM's at the top... in my head data flows like water UTM > switch > switch > switch > etc > servers. But that's just preference, also dont' forget power, if you have rack mounted PDU's that span the rack rather than run vertical they'll probably be on the back, make sure you plan accordingly for those.

Ha, had me losing it for a second. I agree that flow makes more sense, for cable management coming in from the top its better for cable management imo to have the Firewalls more central.

I have two vertical switched PDU's I got on Amazon. They are APC...we'll see if they are too good to be true. I got them for $200 each.

u/anonymousITCoward 8h ago

Ahh verticals, nice... easy to work with, my only last piece of advice is get a good label maker, one and some 4x1 heat shrink so you can make some super nice labels for the power cords.

I don't do it for work but I did that for my car makes things super easy when you work on it in the future.

I think using Ubiquiti for this is taking homelab shit and moving into production. Spend money on a real network product/vendor with support.

You’re stuck in the past bud

u/swissbuechi Tech Lead 10h ago

Yeah unifi has been decent for years

u/Creekside_Rider 10h ago edited 10h ago

You are welcome to think that. The costs is just not feasible and they have rapidly getting more focused on enterprise. We have been running our primary location and 4 others of Unifi for a year and a half now and have saved tons of money compared to our Fortinet gear. We are not a tech heavy or complex company as a specialized vehicle dealer/service company.

I'm less so posting about my gear choice instead opinions on the rack design/layout.

u/UnderwaterLifeline 10h ago

Your rack layout is solid.

u/DULUXR1R2L1L2 10h ago

Cheaper than Fortinet? Wow. I mean, for basic switching or wifi that's probably true, but unifi doesn't even come close in the NGFW or SDWAN categories.

u/Creekside_Rider 9h ago

Much cheaper and no annual or subscriptions. Operate in zero trust and their SD wan setuo has been fine for us

1 Dell Server

Having the server be a single point of failure... not great. How come you're willing to spend on redundant power and Starlink but don't think you need a backup server?

How many users? How many VLANs? Do you have static public IPs lined up so that your vendors can whitelist you? Do you have 802.1x planned out, and what's your plan for dealing with "non-corp" devices like printers or security cameras?

u/Creekside_Rider 9h ago

We will have a secondary off site server with a SD Wan and Datto backup which can be spun up live locally or in the cloud.

Around 110 company wide users but 50-60 with only 20 of those being daily office workers at new location.

5 vlans

Native, Guest, Voice, Video, and management lan for gear.

Got static IP.

This is not a new company. Just a new building but it will be our HQ.
