I'm glad to see UBNT in this space.

I've always used ZFS because it's vastly superior to other options. When I see storage companies building without fault tolerance, or without a merkle tree (so that you can backup deltas efficiently without having to recompute them) it's a sign their marketing team has more influence over the company than their engineers.

Sadly, the few ZFS COTS options have been somewhat underpowered. QNAP supports ZFS filesystems, but their backup configuration won't let you arrange for a nas to pull from the source (instead of the source doing a push.) You can still pull it off by scheduling your own cron job, but this somewhat defeats the purpose of paying extra for a vendor solution.

UBNT is still supporting my 15 year old edgerouters with security updates, and their interface is clean and usable for anyone with basic network experience. And their video surveillance solutions are unusual in that they allow you to keep your footage entirely onsite and offline, an uncommon level of privacy. If they can bring the same polish to their storage solutions, I'll be using these new products for a long time.

The same is true for our AI processing on the cameras. This is entirely local and private. You can even air gap the UniFi Protect system from the Internet and it'll operate fine.

Ubiquiti's biggest feature is no monthly recurring cost. I really hope they continue the streak on products like this. Seems like anything else bought up these days is switched to an MRR model with no vision into the long term viability.

I tend to agree with you.

In my opinion, as long as the majority of their profits come from people continuing to buy the self-host devices, it is fairly unlikely they'll ever stop offering those devices. Why change a working business model?

Yes, subscription models are enticing for that recurring revenue... number must go up, right? /s

If a majority of your sales are not in subscription products though, I think it would be foolish for a business to blow off its own leg trying to chase that particular dragon.

Then again... businesses have made dumber calls in the past out of nowhere...

I have heard others say the same as you about Ubiquiti devices. I genuinely curious what bottlenecks you've hit.

I've only been using Ubiquiti as a pro-sumer, but it has held up well for my use case of Plex and little game servers.

I use a Synology NAS for my storage though, which is a slightly beefier mobile AMD chipset.

I'd be very interested to know what I should and shouldn't expect from my ARM based network stack though!

The Cloud Key Gen 2 is underpowered depending what you do with it, and it runs hot. UniFi seriously needs to refresh it. (At least it’s better than the Gen 1. The Gen 1 was disastrously bad.)

The ENAS looks like fairly nice hardware. It even has ECC RAM. Not cheap, though.

> I genuinely curious what bottlenecks you've hit.

1. My UDM Pro absolutely chokes and stalls with intrusion detection enabled on the firewall and 8 cameras connected. Network goes down, cameras disconnect, devices disconnect from Wi-Fi every time a car drives past a camera due to AI features triggering, etc.

For something meant for small businesses I wish they would just shove an Intel i5 or something in it. They make great switches, great APs, great everything else, just too stingy on processors on the few pieces of central equipment that people would actually be willing to spend more on.

And for a $3999 enterprise NAS with dual 25 Gbps SFP ports and 16 drives? It could surely use something more beefy than a Neoverse N2. I'd say an i7 or even i9 is warranted here.

3. The UNAS 8 I don't own but I believe it would struggle with >1Gbps links and encryption enabled

Can you actually saturate the links with the spinning drives?

I've had the hardest time making my TrueNAS ZFS server fast when it was filled with HDD spinning disks. I initially also had 12 of them trying to get maximum speed. I have 128GB RAM and a 10G ethernet connection. I tried all types of optimizations like L2ARC via NVMe, etc, and it wasn't very effective and just too much time spent tweaking and testing.

Instead I just threw up my hands and replaced all the spinning disks with NVMe drives for the data I actually shared (8x 4TB NVMe drives.) And now it very usable and no need for LRArc, etc. Random or streaming access is equally fast.

Best choice I made. Now I did do this over a year ago so I skipped the NVMe price inflation.

I still keep 4 spinning disks but it is for archival data that I expect to never access unless something bad happens. It is slow and I use it like a tape drive.

I have a backup node with a 40G NIC & a ZFS pool of just 8x HDDs set up as a pool of two RAIDZ1 vdevs striped together (i.e. 4x drives in raidz1-0 & 4x drives in raidz1-1 make up the "backup" pool). Pulling to another server I usually get ~11-12 Gbps over NFS.

Honestly, outside of random access/small file access, my primary NVMe ZFS server isn't all that much faster in raw throughput despite being 22x NVMe drives going direct to the CPU instead of 8 HDDs going through a SATA controller. I think it's easier to hit other bottlenecks with ZFS/network transfers well before the disk performance itself (some of which I could probably optimize away if I could be bothered - e.g. enabling jumbo frames for NFS did still give a perf/efficiency bonus even on modern hardware). Per core CPU performance seems to play a big role in a lot of ZFS things too, even though the cores don't look very busy in htop.

There can easily be a bottleneck depending on how the setup the sata/sas, but if you can get sustained sequential reads or writes, 16x drives at 6 Gbps sata should be able to saturate 2x 25 Gbps ethernet. The store link shows two expansion ports as well which should help get bandwidth to the point where 25 Gbps is useful.

Less likely with random reads/writes or mixed use.

with the zil/slog on nvme yes -- you would want redundant power, UPS and a raid of nvme drives but with all that in place the data would get securely written to flash media before being flushed to spinning rust.

Is this some xBSD or UniFi OS (debian) with ZFSoL? Can't tell from what they've written. 8C+64GB: enough for essential block+file service, but not for dedup and other demanding ZFS features. Also, doesn't appear the controller is redundant; just the power supplies. iSCSI is headlined; nice they didn't limit this to file. No mention of object store, or NVMe-oF.

Seems like a nice, basic, affordable platform for workgroup/SME stuff. Not NetApp/Pure Storage "enterprise" grade though.

They seem to follow the anti-corruption layer model for most of their offerings, so I would expect they use what ever OS is best supported by the upstream.

It is a large reason they can mitigate vendor risk IMHO, offering different tiers of switches as an example without being held hostage by on particular switch IC vendor like many brands.

I do wish someone would take up comstar though, netapp bought and killed several jbod lines etc… to kill it before Oracle bought Sun and also killed it to protect their enterprise storage offerings.

NVMe-oF may be a possibility because there are FPGA IP vendors but without comstar there are some challenges IMHO.

That seems reasonable, I don't buy NAS for datacenters (just run a modest 80tb one for my home lab) but equivalent rackmount 16-bay ones from other vendors would be more expensive (maybe $5k-6k?) and with less polish.

That's without storage. They are charging $750 each for 24tb HDD's, so filling it up brings that cost to $16k. Only need to run it for 13+ years and have zero HDD failures in that time, and then pay for all the media you are going to load it up with. Not exactly sure this would be cheaper or easier than just paying for streaming services and cancelling them when you don't need them.

i like their gear, I bought a whole bunch, but I couldn't and can't figure out how to give my wife access to their Protect app as well. It's absurd to the point where their MFA sent doesn't work when trying to authorize her - and judging by reddit posts etc I'm not the only one. Such mundane things are where UI falls apart, wrong details. Instead of giving elves resources to pack each individual rackmount screw, if they spent some more time on workflows and software, they'd be a truly great company.

I was literally looking today to see if there was any news on this, because it’s been widely assumed that they’d release it.

$4000 is… a lot. I can buy a used CSE-846 for about 1/4 of that, an X10–era mobo for a few hundred bucks, and have 1.5x the bays (tbf, also 4U instead of 3U). Managing ZFS is just not that hard; it’s not Ceph. If you want easy mode, throw TrueNAS on it, and you’ll get an awesome UX that abstracts away everything difficult.

If this were < $3000, I’d probably buy it. I’ve been holding off on replacing my two CSE-826 because I’ve been waiting for this to come out. Disappointing.

Never went away, Linux is now the primary target platform for OpenZFS (which is basically synonymous with ZFS these days). TrueNAS/iXSystems (probably the main commercial company using ZFS) moved from FreeBSD to Linux. Major new features like pool expansion have been added after years of requests. Etc., it's a good time for ZFS on Linux.

There ARE licensing issues related to shipping it compiled into the kernel, but you can install it as a kernel module on every mainline distro nowadays which is functionally the same from a user perspective.

ZFS on Linux works great, but with most distributions, it will compile the kernel module on device upon installation. Only Ubuntu distributes binaries.

As a consequence, you don't necessarily want a rolling distro, as the ZFS module can get out of sync with the kernel.

ZFS itself is build for both BSD and Linux from the same source, so there's feature parity there.

I've got a fully 10GbE + WiFi 7 network w/ Ubiquiti gear already, would love to ditch my janky DIY NAS setup for something that is integrated with the rest and could potentially give me a better backup setup for my photography as well as enough storage to act as a media server.

I have a UNAS-Pro, which runs the same Unifi Drive software as this, and it works great for Time Machine backups. Dead simple.

I also have tons of other Ubiquiti gear, and honestly there's not a ton of synergy between the NAS and everything else. It's a great NAS though. And also, it's only a NAS. It's not an application server like a Synology NAS.

Wireless Time Machine backup works until one day, Time Machine decides to shit the bed. Do not trust it. Invest in a different backup solution if your data is at all important to you. Something like Arq or Backblaze or tarsnap.

I use the 3-2-1 strategy for backups. I keep one copy off-site by using cloud backups, currently I primarily use Backblaze for that purpose but am considering alternatives for several reasons. I keep a second copy on an external SSD via Time Machine, and I keep one copy on-device. I'd like to use network Time Machine to get rid of the inconvenience of having a bunch of USB external SSDs floating around, especially since none of them are large enough to backup my entire drive if I get close to filling it.

I appreciate the perspective, I definitely take backups seriously for my photography.

I think a combination of:

1/ ZFS datasets with hourly (or daily) snapshots

2/ Samba with vfs_fruit

Gives the peace of mind that even when the sparsebundle shits the bed, you can rollback to a suitable snapshot and only lose a small period of backups, rather than having to lose the entire history and start again from scratch.

(I say when, not if, through considerable experience over the last 15 years that it will always, inevitably, shit the bed.)

Are Ubiquiti products commonplace for companies that contract with the US government outside of the DoD/DoW?

Since DoD/DoW generally requires STIG compliance, and none authored are for any specific Ubiquiti product, we can cross that off the list. Sure they can get exceptions or use a more generalized STIG but stakeholders generally have pre-defined limitations on what they will and will not allow on networks they sponsor.

I've recently been convinced to implement a Unifi stack for my home network. I got a Cloud Gateway, a 10G switch and a couple WiFi APs.

The Cloud Gateway will be sold or given away. It's utter crap. I'm now building an OpenWRT container on IncusOS as my Internet gateway/router.

The switch is meh. It's easy to admin, which is nice - though I'm having to run UnifiOS on another container on said IncusOS.

The APs are fine. Decent power and the central administration with the switch is actually quite nice.

If I knew everything I know now, I wouldn't have bought any of those but they will do for now.

IPv6 support is basic at best. The zone-based firewall is very prescriptive and limited. ACL stuff is not great. To increase the MTU of the physical interface connected to the ISP I would need to hack a systemd unit that did it on boot (I either need it at 1508 so the PPPoE interface uses 1500, or I need to MSS clamp it and have it effectively reduced to 1492). Initial configuration requires the device to be connected to the Internet.

There were a few other niggles, and in the end I just found it easier to do what I need on OpenWRT.

I really like the DM Pro and have it deployed to an office of about 50 people. It's a pretty no-fuss solution and fairly simple to manage.

For my personal setup, I decided to go with OPNSense and I couldn't be happier. Much more control, at the cost of being a little more hands on.

I think the best (rough) comparison here is MacOS vs Linux (or more accurately in this case, FreeBSD).

Apart from the shitty software and basic features either missing or locked behind a monthly cost, the network itself is not bad at all, I get 600-700mbps on wifi throughout the house and have my servers wired on 2.5gbe

But the one thing I really thought I was buying into by choosing an amazon brand was ease when it came to buying upgrades, and yet I ended up having to buy extra hardware (like the wired gateway) from ebay and sellers in the US as amazon does not sell their own hardware everywhere

I've had standalone routers, Eero Pro, Google Wifi, TP Link Deco, TP Link Omada, and probably some I'm forgetting. They all had something that just enraged me.

I finally bought a Unifi and I'm very happy with it so far, 6 months in. There's a few things I haven't tried, like rebooting it while it doesn't have an internet connection (I'm looking at you, Deco!), but so far my big complaints are that it's opinionated about the initial setup, and setting up a static IP for a device that isn't connected yet is a serious PITA. I had devices on my old system that I didn't want to have to change IPs (because the computers talk to each other) and that was not easy. If I had to do it again, I'd probably just let it do what it wants and deal with changing all those configs to the new IPs.

FWIW, I just have it as a router, and my Wifi is still some of my expensive standalone Asus wifi routers acting as just access points. I didn't see a point in replacing them when they were working great as APs.

I looked around a little. the C&D from Netapp was in ~July 2010 and the partnership and product with Oracle in the Fall (Around the cease fire) and we continued with that (via the Oracle Partnership) through 2011-2015 when the company ran out of cash and laid us all off.
