How do you future-proof a home or small office network?

[rosiecharles]

Hi everyone,

I'm planning a small network upgrade and was wondering how others prepare their networks for future needs.

Do you usually invest in higher-speed switches and better cabling from the start, or do you upgrade only when necessary?

I'd be interested in hearing what has worked well for you and any lessons you've learned over time.

Thanks!

Depends on what you need. Might be a bit clearer on what you plan to do with it.

Sort of a waste if you get the newest and greatest, but don't know how to use it.

I hate the term, "future-proof." We saw it back in the 90's / 2000's, if not before. You cannot future-proof anything, since there is no definition of how far into the future you plan on prepping for.

Best idea is to tell us what you currently have and what its use is at the moment, and we can then offer ideas about some areas that might need an upgrade and other areas that can be left alone.

Personally, I’ve found that it’s usually worth investing in the infrastructure you don’t want to replace later, especially cabling. Running Cat6A (or better, depending on your needs) during an upgrade is relatively inexpensive compared to having to re-cable a few years down the road.

For switches I try to balance current specs with realistic growth. If my budget allows it Ill choose switches with higher uplink speeds which leaves room for expanding later on, but I don’t necessarily overspend on access ports if the endpoints won’t benefit from them anytime soon.

One lesson I’ve learned is that planning for scalability pays off. It’s much easier to add devices, VLANs, or higher-bandwidth workloads when your network infrastructure already supports it than to replace hardware later. 

What is your budget like?

When I think about a network, there are really two aspects, the hardware and the wiring. So here is what I would do for both.

Wiring:

• Use Cat6A for the patch panel, outlets, and all structured cables (cables installed in walls).
• Run plenty of Wireless Access Point (WAP) cables, as a general rule, assume a signal can only pass through 2-3 walls and can't pass through a floor (that is conservative, but trust me on this if you want strong WiFi) 
• Cat6 patch cables are fine for now if you don't plan to run 10gig, those are easy to replace later if needed.
• Run OS2 single-mode fiber to anywhere you think you may have a server or sub-switch. (yes, single-mode for everything on a small network, don't mess with multimode unless you are at a scale where that minor cost and power savings will matter).
• If you really want to future proof, also run fiber to any high density WAP locations, it is likely that WiFi 8 and beyond WAPs will push the limits of 10g.
• Run 6-12 pairs of single-mode fiber between your MDF and the building's MDF, even if you only need 1 or 2 pairs now, those extra pairs will pay off down the road.

Hardware: (its easy to say "get all the features incase you need them", so instead of futureproofing, I am going to take approach of suggesting areas worth investing in, and areas you can save money).

• Don't overspend thinking you need every feature on every port. You don't need 10g on every port, you don't need PoE on every port.
• Don't overspend on redundancy either, unless you are ready to buy two of everything, don't waste money buying two of some things and not others. Dual power supplies are worthwhile, but probably not HA or multi-path redundancy. 
• Get 1 "distribution layer" switch that your router/firewall will connect to as well as all your access layer switches below. This should be a fully managed 10g+ switch with a combination of copper and SPF ports, a few 25g uplink ports are nice for this switch.
• Given that you said it is a small network, I suggest also using that distribution layer switch for servers and WAPs, meaning it will need PoE.
• Speaking of wireless, get good professional tri-band WAPs, and either turn on the band stirring options, or limit 2.4 to an IoT only SSID. This will provide a solid WiFi capable nearly everything but the highest of bandwidth clients...you could even consider skipping wiring workstations depending on usage.
• Access layer switch for workstations and printers can be cheaper switches, 2.5g is a good sweet spot between price and future proofing, but even 1g is fine for most individual clients. These switches are easy to replace later, so don't pay for 10g ports if you don't need them now, they will likely be a lot cheaper in 5 years.
• You can consider saving a little on access layer switches by only getting 1 PoE switch for whatever needs it (remember your WAPs are connecting to the distribution switch, not here), and non-PoE for your workstations, because desk phones are falling out of favor.
• You can also save money here by not buying managed switches if you don't need them--but really do some soul searching there, if you go this route, then anything that isn't on your workstation VLAN would either need to be connected to the distribution switch, or its own access layer switch.
• Also, don't feel like you need a fancy fabric stacking switches for your access layer, that is the point of the higher-end distribution layer, to remove the need for things like that at this level.

Home Hardware:

• I'm realizing the above assumed an office setting, if this if for your house and home lab then the above still applies, but you'll probably want everything managed and PoE, just because, but you probably also don't need multiple access layer switches.
• If your total port count is below 24, just skip separating distribution layer and access layer and just get one nice switch with the features you want.
• If you are at the point of considering a 48-port switch, I would instead get a nice high-end distribution switch for things that need it, and cheaper access layer switches with specs based on the needs of connected devices.
• For home use, don't worry about home running every device to the main switch, there is nothing wrong with running sub-switches for your media areas and office, those essentially become your access layer, just look for sub-switches with a 10g uplink so sharing bandwidth isn't an issue. Just make sure you always connect them to your distribution/main switch, don't daisy chain, the path should never have more steps than Client>Access>Distribution>Firewall>Internet or Client>Access>Distribution>Server if it is local.

Depending how you’re wiring it internally, but try to put it inside conduit, that way in the future you can more easily replace cables, compared to running inside studs alone

At least cat6a too

Thanks for the feedback. That's a fair point.

This is mainly for a small home office setup with a few wired devices, Wi-Fi for laptops and mobile devices, and room for a NAS in the future. I'm trying to avoid replacing the core networking equipment too soon while keeping the budget reasonable.

I appreciate your advice.

I understand what you mean, and that's a good point.

I probably should have said "planning for future upgrades" rather than trying to future-proof everything. My goal is simply to avoid making decisions now that I'll regret in a couple of years.

Thanks for pointing that out.

Thanks for taking the time to write such a detailed explanation.
I hadn't considered running fiber for future expansion, so that's something I'll definitely read more about.
