Why is 10 Gb Ethernet still so expensive?

Journey said:
I've just finished a test build with the ASRock X570D4I-2T which is a mini-ITX board, that has dual Intel 10GbE X550, configured with with a 4x 1TB NVMe M.2 drives in a 16x adapter, and 4x 14TB WD Red drives, using a basic Ryzen 5 Pro 3600, and 64GB 3200MHz RAM, in a SilverStone Technology DS380, and an SX700-PT (total overkill but that's all we had lying around).

Board is great, although I did need to get a beta BIOS to get the birfurcation working correctly on the 16x M.2 card, but the performance is exactly what you'd expect, and the board is well priced at ~£350 + VAT

That's a system and a half :eek:

Wow sounds fantastic :)

Not for me, but the business who are deploying them seem to be happy with the spec, they've only had it a week so far though. Would love to get the BoM finished once we've had the feedback, and it's been tested for the necessary 30+ days up-time with no failures. They are running a custom Linux build on it, so I don't have to do anything with the software luckily :D
 
I could probably do with 10GB well maybe not quite the full amount but faster than Gigabit.

I have 3 switches in my home and I need a fourth.

I also have 3 access points and a ubiquiti usg and controller.

To upgrade everything probably be £1k so not worth it.

Looks good.

I'm going to start read the xpenology forum and see what systems it supports now.

So you want to buy decent hardware, but run a highly dubious/patched installer to rip off Synology’s software with a history of breaking on updates?

I used xpenology for years with no problems.
DSM is based on Open Source code.

Qnap and synology are way over priced in terms of hardware and software.

Which isn't the same as what Avalon said? It regularly breaks when Synology release updates, requiring waiting for new "loaders" to support the later updates.

I don't disagree, however they just work, and they are still the better options imo.

Xpenology - unsupported, delayed/risky updates
FreeNAS - Elitest "ZFS is the best" attitude, despite ZFS still being difficult to expand arrays etc
Unraid - performance limited to single disk performance
OpenMediaVault - single Developer

I never had a problem.

Having a problem is largely irrelevant when you are openly stealing the product. Just so i’m clear, piracy is OK if a commercial developer builds it’s products on GNU/GPL etc. code and is perceived as over charging for its hardware/software/support - isn’t that pretty much everything commercial? You claim this in the thread you happily derailed from a discussion about the cost of 10Gb to ‘Spec me a 10Gb NAS’, with a minor detour into your amazement that USB3 is a thing, while potentially dropping north of a grand on hardware (but not software), and now it’s been pointed out, you’d like to get back on topic.

OK then, it’s £60/port based on 4 ports/devices using a Mikrotik SFP+ switch and Mellanox CX2 or CX3’s. Intel x520’s are another option, but tend to be more pricey. Avoid the Dell hybrid SFP+ switches, last I looked the IPv6 was very limited, it can be worked around, but for similar money you can have a new Mikrotik with the same SFP+ port count and LTS. The other consideration is removing the network bottleneck just shifts the issue elsewhere, obviously that’s CPU/storage and the secondary considerations of protocol and write endurance. I quite like large enterprise MLC fusion.io cards, write endurance is obscene and they can saturate 10Gb, just beware modern OS support is getting more limited, a 3rd party driver is available for Ubuntu/Debian/Proxmox etc. but official ESXi support was dropped in v7, Windows is fine.
 
Yup, I guess you could throw something bigger than Ryzen 5 (Ryzen 7 3700X has 65w TDP) but cooling anything bigger in that case might be a limiting factor.

Super duper NAS with plenty of horsepower for some VMs/Dockers etc, I’m considering selling my Gen8 Microserver and some others “bits” to fund something very much like that build.

As I only want to transfer files.
Would a Intel® Xeon® D-1521 quad-core 2.4 GHz processor, Max turbo to 2.7 GHz be ok?

Reason is that I have found a Qnap which has 12 3.5 bays and 4 ssd bays and 2 10GB ports for about £1,200

More than ample, I don’t know what throughput you’ll see, you’re obviously not going to saturate 10GigE unless you have something pretty fast on either end (more to do with I/O of the storage subsystem than the CPU)
 
Got my MikroTik CRS305-1G-4S+IN plugged in, using a Intel X520-2 NIC (10GBASE-T SFP+ Copper RJ45) in my X399 Taichi, might need some tweaking as I'm seeing about 350Mbps from my Xpenlogy with 5 x 5TB WD REDS (seems quite bursty).

Literally I've just plugged it all together so I'd be interested to hear what others have done to improve performance?
 
The switch is already enabled out of the box for jumbo frames.

But you may be at the limit of what the drives can do, they're 5400 rpm. I get around 400 MB/s with 4x Seagate Iron Wolfs which are a bit quicker than the Reds.
 
Agreed and I don't want to spend hours chasing the tigers tail, I do have another PC (currently in bits) which I should be able to do some M.2 SSD to SSD transfer testing.

This has basically cost me peanuts as I already had the NICs and SFPs. In the medium term I want to run a fiber from my house to the barn, I've got a 1/4 height rack so that I can stick lots of my junk out there ;)
