Why is 10 Gb Ethernet still so expensive?

So I didn't have much luck with Sedna - M2 (2280) PCIe M Key to 5 x SATA 6G Adapter Card, just doesn't seem to work with X10SDV-8C+-LN2F, I will just return. Also the m.2 port on the MOBO is shared with SATA0 so perf. wouldn't have been great. (I might try in my x399 board just to see if it works in that if I have time)

So I would really like some more SATA ports but if I use the 1 x PCI-E then I can't use my 10GigE card (Intel x520-DA2), so it does seem that X10SDV-8C+-LN2F supports 8x8x bifurcation on the 1 x PCIE-3 x 16 so I've ordered a riser. This will allow me to use both an HBA Card and the Intel x520-DA2 for 10GigE, mounting could be "exciting" but I'll cross that bridge when I come to it ;)

So build is currently waiting for a compelling Black Friday shuck deal (I'm aware of 12TB Elements) as I'm going to move on from the 6TB reds to a higher density drive. I'm caught between the 12TB Elements and the 16TB Seagate Expansion Desktop (EXOS Enterprise drive). While the 16TB are a bit more expensive it leaves me more physical room to expand in the future.

I could but it's gonna share bandwidth with SATA0, given that MOBO supports 8x8x bifurcation on PCI-E 16x slot I decided to go this route instead, thoughts?

How will you securely mount the cards - I assume you only need a cheap/dumb riser as the board should support x8/x8 (and possibly x4/x4/x4/x4?)

Was a good price - could always sell it and get something in AM4 / MATX for similar money? Or reduce number of drives... (or use some of the USB headers / ports for some of the disks... - though I'm not a fan of this unless there's no alternative)
 
According to the manual "A proper riser card must be used to take advantage of bifurication. The options are x8x8 and x16", I was recommended "C_Payne: PCB Design & Prototypes products" and have purchased a riser from there. I will probably get a flexible PCI-E x16 to connect it all up, there is plenty of room in the case, mounting should be OK.

Just don't want to go down the usb route.

That said I might being trying to make a silk purse from a pigs ear, it could just be better flicking the X10SDV-8C+-LN2F on and going down the AM4 / MATX route as you say, hmmmmm.

Have been pleased with my AM4 server builds - cheap as chips for boards, wide selection of CPUs, and I've had no issues with HBAs, 10G NICs, or even ECC support on the right boards

The gotcha is display output - not all boards play nicely when headless and using an APU halves the number of lanes to the first PCIE slot (and only the Pro versions of the APUs have ECC support). Also worth noting that very very few boards offer IPMI unfortunately.

I've used these PCIEx1 GFX cards to solve this in my builds:
  • Zotac GeForce® GT 710 1GB PCIE x 1 (there's a 730 version as well)
  • Asus GT710-4H-SL-2GD5
This board is about £90 and should offer enough PCIE / storage (some lane sharing on second M2 slot with SATA though) - and the integrated NIC is not a good one: https://www.asrock.com/MB/AMD/B550M Pro4/index.asp#Specification

Best AM4 boards for this are by ASRockRack - they have IPMI, and some have 10GB nics integrated - not cheap at all though
 
SFP+ connectors cannot auto-negotiate so it will run at whatever options you have on the speed selector or your device. Most are 1GbE or 10GbE but there are chipsets starting to come through that also have the 2.5GbE and 5GbE options. If you have those options then a 10GbE SFP+ RJ45 adapter will let you connect to your motherboard with a standard ethernet cable (preferably CAT6). If you don't then your motherboard will likely run at 1GbE. Or you could add a 10GbE PCIe card or Thunderbolt adapter to the PC (if it has thunderbolt).
 
So my new NAS is up and running (went the Xpenology route again, I know some won't like that), just copying data across now, the bulk is 13TB which I kicked off at approx 22:00 last night and I'm approx 60% done.

Had a bit of a headache with some mini SAS cable didn’t realise you need SATA (host) to SFF-8463 (target) cable, I just though it’s was all the same so case is still a bit of a mess until those arrive.

Sounding good so far :)
I wish I could put Xpenology on my qnap :)
 
I shucked a 3 x 16TB Segate external enclosures, get's you a really nice 16TB EXOS 7200 rpm drive

Interestingly if you put the drive serial number in the tool it show them we their own warranty (not part of a component).

Put it into the returns application and what does it say? It may well be they have no way to track who is building what drives into what devices or which retail stream but I suspect they know exactly where that drive went off the production line.
