Ubiquiti Unifi Security Gateway Pro (USG-PRO-4) for reliablity??

Hi to all, I have a new client that wants a failover solution in their medical office of about 25 or so PC's and servers.  I have been putting in the USG 3 versions and been good and solid so far with many other clients... (1 failed but within 30 days to Amazon and they sent me a new one thats been good)

so I am thinking of using the USG Pro 4 model but I see sooooo many restarts, failures, etc on that particular model????

I want the Pro 4 model to have rackmountable and to do the failover when the 1st WAN goes down???? Then comes right back up off the secondary when main pipe comes back up... so the client has NO DOWNTIME at all.

 

Please give me honest reviews of all that would purchase a Pro 4 and feel 100% on it for what I need.............. or go another brand for safety??  Being a full medical center... this has to be 99.999999999999999999999999999999999999999% reliable.

 

Thanks!!!

Re: Ubiquiti Unifi Security Gateway Pro (USG-PRO-4) for reliablity??

I'm running a USG-Pro in our law firm.

We also have a US-24-500W, US-16-150 and US-8-150W, UAP-AC-Pro.

There's about 40 clients on the network, being PCs, IP phones, cameras,MFPs etc and on various VLANS.

 

The USG has been rock solid for us with no restarts etc. Granted, we've only had it for about two months.

 

We don't have a failover WAN connection as our current service has never failed, but I am looking at connecting a Nightwak LTE modem as a failover.

 

I wouldnt hesitate recomending the USG Pro, been very happy with it.

Re: Ubiquiti Unifi Security Gateway Pro (USG-PRO-4) for reliablity??

When I first got USG Pro many months ago, I vaguely remember it randomly rebooting once in a while. I say vaguely, because I can't remember the last time it rebooted unexpectedly or had an issue. It has been running very well for many months now. I think new firmwares have made it stable. I have upgraded to USG XG, but I am reluctant to part with my USG Pro because it has been so reliable as far as I can remember.

Re: Ubiquiti Unifi Security Gateway Pro (USG-PRO-4) for reliablity??

I'm sure you've considered most of this, but wanted to add that you might want to have a detailed discussed with the management or legal department of the medical office to attempt to codify and document the practice's expectations for the network and reliability. I would review your plans and concerns with them to ensure that it's clear you've done everything possible on your side to understand and meet their requirements, for both safety and liability reasons.

 

For instance, in some medical offices, such as specialist practices and ones with some minor on-site surgical facilities, the computers and associated EMRs systems are considered life critical systems, meaning that if they fail the health and safety of patients may be at risk (for instance, a patient having a medical emergency in need of a medication, and the providers unable to look up the allergy list on the EMR, would be a risk to a paitent's life/health). This would suggest that you may need to look at other, non-UniFi options that support high availability and more complete failover features.

 

Overall, there are many different classes of IT networks in medical environments, and the more critical applications should be codified with specifics by the practice and made clear to you. And depending on the size and scope of the office, none or some of this may apply. But I've had some experience in the medical field and wanted to mention these things to be aware of in case if helps

This client I see has a CheckPoint box that the little old Cisco router is patched too.   Do I still have to keep that or the Unifi Pro 4 do all and secure enough to do what both of those boxes do????

Buy more than one and spare RAM modules. You may be lucky but there have been many users including me that have had issues with stability - restarts due to "Unhandled kernel unaligned access". One assumes a  minority, but still evident enough to bring risk into the equation.

I would definitely agree that anyone installing these in a business environment should buy at least two because stuff does fail.  

 

I'm not so sure on the RAM. There was a memory leak that was fixed by upgrading the RAM from 2Gb to 4Gb and I think there was an isolated batch of 'bad' RAM that had issues. I have all my USG-4Ps upgraded to 8Gb RAM now because they do run faster like that. I don't think the RAM itself is a user-serviceable part and I wouldn't necessarily suggest that anyone carries spares of RAM. It can't hurt though.

Replacing the RAM with a new 4G module prevented daily restarts for me. It wasn't until recent firmware that the problem arose, my USG Pro was purchased in Ocf 2016. Howver both old and new units have had the same issue so one would assume its not a bad batch of RAM.I believe its just masking the issue.  There are many references to it  https://community.ubnt.com/t5/UniFi-Routing-Switching/USG-Pro-4-Restarting-every-2-days/td-p/1563145...

Have also done same as @rgunn

My USG unit is from late 2017. Replaced ram with 4GB module and reboots stopped (for now).

Running 4.4.18 because of other (dashboard) issues with 4.4.21 and 4.4.22.

 

Other than that it's a great router!

Re: Ubiquiti Unifi Security Gateway Pro (USG-PRO-4) for reliablity??

Interesting, I hadn't seen that. I know there was a memory leak in one version of the controller but that was fixed. I use a mixture of USG-4P and USG-3P and have cold-swap spares of both but touch-wood, I haven't seen this issue on any of them. I do routinely swap the RAM on the 4Ps for 8Gb Crucial PC1600MHz SODIMMs as it really does speed up the unit quite significantly.

I'm still on 4.4.12 because its properly stable. I always wait a couple of weeks before updating the firmware and there were so many issues around 4.4.18 that I just left it on 4.4.12. Unless you need the port remapping functions in 5.8.x Beta controller you don't need anything beyond 4.4.12 to keep all the controller functions. It's stable and I have no issues so I'm leaving it alone!

Re: Ubiquiti Unifi Security Gateway Pro (USG-PRO-4) for reliablity??

Maybe that is the ticket for 100% 4Pro router???  Buy latest build and go ahead and buy a 8gb stick and replace it from the start before it goes out in a production environment..........

 

Anyone know anything about a Checkpoint box on the network???

In what way do you notice the speed improvements?

In my case the replacement with a 4GB module was to try and prevent restarts, not to increase RAM capacity. Now 9 days without one.

 

No noticeable speed changes. None were expected anyway, as memory utilisation was never an issue. It was to see if it prevented kernel panics due to unaligned kernel access. I have DPI, IPS and Geo filtering enabled. As you can see below there is no memory pressure.
