Ubiquiti: Enterprise NAS, Built on ZFS(blog.ui.com) |
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.
Do they have ecc on those models? Do you have an example model on hand?
They will at some point just cash out.
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!
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.
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 me a decent perf/efficiency bonus even on modern hardware). Per core CPU performance seems to play a big role in a lot of ZFS things too (especially if you enable a lot of the extra features), 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.
$3999
Edit: Drives are not included :(
(Not that you need that much for canceling streaming, I’d get a home Synology or diy TrueNAS for that anyway)
Seems like a nice, basic, affordable platform for workgroup/SME stuff. Not NetApp/Pure Storage "enterprise" grade though.
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.
$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.
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.
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.
Would be nice to have a CSI, but I can probably just use democratic-csi like I already do on my homemade ZFS based storage appliance.
This looks like a dig at Synology, who do this.
I'm not at all surprised that Ubiquiti is getting ahead of that and promising it from the start.
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.
I appreciate the perspective, I definitely take backups seriously for my photography.
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.
After a long time they introduced ONVIF into their camera products which basically opened it to everyone.
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.
What needs do you have for a router that the Cloud Gateway is missing or is bad at? A PiHole equivalent is about all I can think I'm missing.
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
source: used to work for a storage vendor that was marketing a NAS based on ZFS and got credible threats from Netapp to the point that we sought a partnership with Oracle that included indemnification under Oracles settlement with Netapp.
Once you invest thousands in network equipment or cameras you’re less likely to jump ship when they start sneaking things in. And this is long lived equipment, not the kind you anyway replace every couple of years. So that’s a relatively strong lock-in.
Boy I hope Broadcom didn’t hear that…
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...

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.)
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.
There were a few other niggles, and in the end I just found it easier to do what I need on OpenWRT.
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).
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
It's even underpowered for streaming -- I found Protect to be extremely laggy, taking often 30+ seconds to open the camera stream when 3-4 stream receivers were connected.
I have a udm se, 10 g3 cams, 4k bullet+ai, door entry + cam +ai, couple of the display viewports running all day and a nano hd access point and symmetric gig with intrusion etc turned on. I also have wireguard users connecting in remotely.
No problems with performance whatsoever at this point.
Ok its not enterprisy its just a small business with 20 people but seems fine to me. I run synology servers.
The ENAS looks like fairly nice hardware. It even has ECC RAM. Not cheap, though.

NetApp originally sued then-independent Sun in 2007, and Sun counter-sued.
Free/TrueNAS/iXsystems has been offering ZFS-based solutions for many years now, and I haven't heard NetApp going after them:
Maybe he was ... they do that sometimes.
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.
I was just a lowly support engineer so not privy to all the legal details that the executives were dealing with. I too had to just take them at their word.
ETA: I searched a bit. Here's a link

Maybe threats were enough? I certainly wouldn't want to test it myself.
