Many people do not use the built-in switch because it only has a gigabit link to the 10g ports I have only seen two set ups where they do use the built-in switch in reality. It is not used that much spending the money to put 2.5 and would only be worth it for the smallest market of the product
Companies who will use this already will have "dedicated" switches, honestly WAY overkill for a small business or home environment. Look at who your audience is for these devices and that should tell you the reason.
Not only have they named it after an iPhone, they’ve had review embargoes like it too 😂 my stream suddenly having three reviews of this in it, but I’ll watch yours first Cameron.
Any chance of some inter-vlan performance testing? I believe the UDM-Pro didn't get anywhere near 10gbps for layer 3 routing between two different vlans, would be interesting to see how much uplift we get for the clock speed increase on the CPU
Quite a bit more expensive than both the UDM Pro and SE. Doesn't make sense to not have PoE at that price point imo. It's just an upgraded SE with some cost cutting.
why PoE on UDM ?? I don't understand.. you should connect PoE switch. does really router and firewall must to have PoE ?? please explain me my confusing...
Great video as always Cameron 👍 Probably a dreamer but I was hoping for an improvement over the 1GbE switch, even to 2.5GbE would've been a nice step up for us home users (with PoE too). Also seeing more devices supporting 2.5GbE lately, even my monitor (with integrated hub) supports it!
I don’t think it would make that much sense because how you would have to get a POE switch to run cameras and access points so this is clearly not an all in one device anymore
I'm so confused, They removed the POE because it's designed for larger setup. But added a extra drive? In a larger setup you will have a separate NVR, either Unifi or more likely whatever vendor is specified by the customer. Also if the switch had a larger pipe to CPU and POE I could see it as a useful NVR replacement/all in one box. As it is, It's a 10Gb SFP router for larger environments, with a NVR and switch for a small environment strapped to it. Love your videos in general, but this device is not useful to me.
Now if they can just fix the software... Traffic stats being the main one. In the almost 3 years I've had my UDM Pro they've never been correct. Upload stats are generally almost correct. Example, download can maintain a 1.2gbps download speed. UDM Pro reports no more than around 100mbps or so. Tired of having to have an OPNsense box as a bridge between my modem and UDM Pro just to see traffic stats. Otherwise the hardware itself is great!! Just wish it was all 2.5G ethernet ports though.
The industry has solved lockable power plugs decades ago, but Ubiquiti had to go and make a proprietary cable. That kind of Apple like thinking is something holding me back from using them for anything but APs
Hi Cameron, I have a 10Gb (real speed around 7Gb) internet connection from my ISP here at home and I am planning to build a network using Ubiquity. Do you think that the standard Dream Machine Pro is capable of reaching 7Gb speed with IDP and security features (that I don't need) disabled?
I have 10gb dobson fiber :) just bought this switch , upgraded my PC's lan cards to 10gb lan cards, and it's insane fast, but what sucks is most online speedtest websites cannot feed me the full 10gb, if I use my dobson fiber internets speed test I get the speeds ... so even with full 10gb most speedtest online websites will still max you out around 2.5gb up / down you will need to use your ISP local test server to get a true test speed. But, when you got 8 people in the house streamking 4k content and your gaming ... setting up multiple VLAN's on my cisco 9300 switch has allowed all the traffic to stay segregated and run fast. I trunk my VLANS through 10gb SFP ports to this UDM pro max and everything is smoothe sailing with online connectivity.
Hello. how are you? I have a question regarding this device versus a USG Pro 4. In the USG Pro 4, LAN ports 1 and 2 are independent ports, and I can configure an independent segment for each of them (each one on VLAN 1). Is this possible with this new line of devices? I purchased a UCG Ultra, and it cannot do this. The UniFiOS only allows creating VLANs, meaning it only has one network on VLAN 1 for the whole device. Which device would allow me to do everything I need? Thanks. Best regards.
UniFi have a capacity calculator here: ui.com/cloud-gateways/resource-calculator. It only shows the regular UDM Pro/SE for now so the Pro Max would either be the same or slightly higher when it comes to camera capacity. In terms of storage, larger drives won't let you run more cameras - they'll just give you longer recording times. If you're needing serious camera capacity then you'd probably still need to go for a dedicated NVR, but a UDM should be more than enough for an average home/small business camera setup.
Openreach has launched 1.8 Gbps on premises with full fibre I think EE are the only ones offering the speed of 1.6 Gbps. But the Openreach ONT has a 2.5 Gbps rj45 port. So when you get upgraded to full fibre/fibre to the home if you haven’t already you should be able to take advantage of the 2.5Gbps WAN port on the UDM pro max.
I'll probably end up hanging onto these for the foreseeable so that I can use them to test other UniFi features/products (I have a second for testing high availability, video coming soon.) However, on the install front, can't say too much right now since stuff is still very much up in the air but if all goes to plan there should be an absolute tonne of install content coming up over the summer!
Say your ISP gives you 2gbit bandwidth with that new WAN port. You can’t actually access more than 1gbit of that using the built in 1gbit switch since the uplink is a single 1gbit to CPU. So you MUST buy a second switch. Can you see why this is in fact bad? It’s not “absolutely fine”. Or maybe you put a file server on the 10gbit SFP port. Same issue.
Don't get me wrong, a higher speed uplink from the internal switch or 2.5gbit LAN ports would be nice, but I imagine that this was all considered by Ubiquiti when designing the product but was deemed not to be worth the additional cost based on the target market. Realistically this device is aimed more towards large scale networks that are going to need significantly more than 8 ports. While 2.5gbit LAN ports would be nice for sure, I imagine the subset of customers who have multi-gig WAN connections but don't have a requirement for additional switches is somewhat small. Of course there's also the option of having the integrated gigabit switch uplinked to the CPU at a higher speed while maintaining the gigabit downstream ports, but then you're still only really targeting people who have a multi-gig connection and are happy with only being able to get a maximum of 1gbps on each individual device. Also, with the way that these are architected internally, you wouldn't really want to have a file server on one of the SFP+ ports and then your clients on the internal switch ports as all of that traffic then needs to be forwarded by the CPU which isn't ideal irrespective of the speed of the link between the switch chip and the CPU. Of course the CPU is no slouch but in that sort of setup you really should be using a dedicated switch so that all of the traffic is being handled by a switch ASIC. My comments around it being "absolutely fine" was more in reference to when the UDMs first came out and there was a complete mess of people misunderstanding the architecture and incorrectly referring to the integrated switch as having "1 gigabit of switching capacity" and then essentially saying that it should never be used. I was basically meaning that the integrated ports are "absolutely fine to use" as long as you're aware that it's uplinked to the CPU at gigabit.
These devices are not designed to operate just by themselves are meant to be part of a bigger ecosystem and the expensive price tag is because you’re going to be spending a lot anyway
Would love to see some videos on peplink devices, very few units have features like bonding and that level of multi wan connections Great video as always Cameron!
It doesn’t make sense to have Poe because if you want a higher reliability for security cameras, it would make sense to get a switch and have a spare one so it can be swapped out very quickly if there’s ever a fault
They reached out to TH-cam users to offer them to review, but associated a press embargo with them. Many tech TH-camrs would then upload their videos as private videos and schedule them for the 'on embargo until…' date instead of applying a time offset.
@@camerongray1515 Removed the POE because it's professional grade hardware, where there will be dedicated POE switch. Well, in a professional environment, there will be a dedicated NVR anyway then. So why not offset the cost and upgrade the CPU. Overclocking a CPU doesn't really bring much to the table.
Have usage in smaller businesses where they want a couple of cameras routing and firewall and several network drops around the building because it’s very easy to set up so they don’t need to hire an expert
Does not seem to be a worth while upgrade over the PRO or SE tbh, no poe (again) and only 5Gb/s on the IDS/IPS so not worth it for someone daft enough to have 10big ones coming into that wan SFP. The PRO and SE are happy with what most of us can get from out FTTP suppliers (1Gb's in the UK maybe going up slightly in the near future), inter Vlan speeds would be interesting though. Cant say the doubling of the hard drives is a big "win" for the money either. Seems like half a step forward - now if it could do 10Gb/s with the toys on.....
I have another and will be releasing a dedicated video on Automatic Shadow Mode shortly 😉. I was just very tight for time over the weekend so had to keep this one short!
There is no such thing as a UDM PRO SE. Either you have the UDM PRO or the UDM SE... and now the new UDM PRO MAX. You only have those 3 options in terms of "Large Scale" devices.
If anything it's a good sign where they'll continue to work with channels that don't exclusively fanboy over their gear. I still really like UniFi stuff and regularly recommend and install it, I just wanted to try something different for home to ensure I was being balanced and trying out other options on the market rather than focussing almost exclusively on UniFi like a lot of other channels do.
Their next version is pro max ++ with 4 ssd , this is just sad man , 1 extra hdd , that toon alot of years to add it to the unused space, other than that 1000 more clients ? Its a sad upgrade that dont deserve the “ max” title
That’s completely pointless as the uplink from the switch is only gigabit and you would likely want to do some special high availability switching for a proper network which this couldn’t support so it doesn’t seem worth it to add it on
@@barhomt that’s likely going to result in a much higher cost as they will have to design their own chips which will cost them millions which will be passed onto the end user at more cost than using a separate switch as well
Please could you test the through put from your isp ? This would give us unlucky people using fttp via pppoe a better idea. ATM an aging cheap draytek can out perform a udm pro.
Deployments of any reasonable size will have dedicated switches which will also handle PoE whereas the dual drive bays would be useful for environments where they want to run Protect on the UDM but also want RAID. The PoE on the SE is great but only really a selling point for small environments where 8 PoE ports is enough, this is targeting much larger deployments.
I literally watch Cameron’s videos primarily for the speed he talks. I can’t stand TH-camrs who drag out every sentence to make their videos longer. I usually end up watching those on 2x playback speed.
