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.

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.

What is the current state of ZFS? I know it had some licensing issues traditionally, despite it being a delight to use every time I've tried it. Is it back?

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 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 stac…

> 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 ma…

Unifi docs say that the AI feature run directly on the camera or via optional devices like the AI Port or AI Key. Odd that it impacts your UDM Pro and wifi.

I just wish they would put better processors in their stuff. Is this yet another NAS powered by an ARM Cortex?

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.

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.

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.

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.

Can I use it without running some inane management VM?

They did it for a very short time. The community backlash was so bad that they recanted immediately. I'm not at all surprised that Ubiquiti is getting ahead of that and promising it from the start.

Kinda, NVME devices still need to be on their HCL and are priced about what you would expect.

> QNAP supports ZFS filesystems Do they have ecc on those models? Do you have an example model on hand?

Some do. I got the TS-873A a few years back, it works. Their software is kind of weird, and I wouldn't connect it to their cloud offering, but it does work.
