Why is 10 Gb Ethernet still so expensive?

Or something homebuilt for a lot less money:

That's quite interesting, will look into that. My QNAP is out of support and getting on now, although it's plenty powerful enough (4970S and 16GB RAM) and since disabling QTier performance has gone up a load.
 
I just had a shock.

My carers son sent round a USB 3.1 Gen2 Hard drive caddy with a 7200 rpm 2 tb HD installed.

I tried it and got an avg of 160 MB sec from my PC to it!
I never knew that USB 3.1 was that fast....

Yeah, I was going to build and all singing all dancing NAS around that case but COVID/work got in the way :)

This case isn't without it idiosyncrasies but it would certainly be on my "very short list", I can imagine heat becoming an issue so maybe one of the lower TDP Ryzens would be in order (restricted height for cooling)
 
I really fancy the CS381 but £300 is just to much for me on a chassis - and no hotswap 2.5 bays or ability to add them (which I'd want on a dream spec machine).

The £100 Silverstone CS380 (build here) is worth a look for an alternative. It's 8 bay SATA/SAS 3.5 hotswap and supports ATX board and PSUs. The two extra 5.25 bays are handy if you want to add 8 2.5" hotswap (or just use the bays internally for something). Probably best value choice at the mo, but can have cooling issues, though some changes can be made to help with that.

In-Win MS08 is good as well (M-ATX) - but doesn't take ATX PSUs and can get a bit pricy.
 
What is it with case vendors that think their stuff is so valuable? I'm pretty sure you can trash a Dell server and replace the chassis for less than that.

I presume ZFS works in software and doesn't need a hardware RAID card?

Yes - in fact you specifically don't want a hardware RAID card, as you ideally need as little as possible between ZFS and the individual drives so that it can correctly deal with errors etc (instead of the RAID card masking them)

A HBA is what you want rather than a RAID card (mostly an LSI model, e.g. rebranded by IBM or Dell)

Good to know, what about a nice EPYC embedded 3251 with RJ45 10G base-T, anything in the market yet?
Click to expand...
Nothing from SM yet for the 3251 with 10GB (they are using Intel i350 for almost entire range) - which makes no sense at all to me when you look at all the goodness in the Epyc 3*** SOC

Not following many other vendors, but there doesn't appear to be that many decent solutions on the market built around Epyc embedded at all (I guess it's because embedded stuff has super long life cycles - so probably lagging a bit behand the rest of the AMD lineup)

ASRock Rack have some great stuff in their catalogue - but getting hold of it is really hard for some reason (X570D4I-2T), this looks good though: https://www.asrockrack.com/general/productdetail.asp?Model=EPYC3451D4I2-2T#Specifications

You can get a R7515 8 core 16 thread 2U server from Dell for £1,615.47 currently with 8x 3.5" bays. Chuck in a 10 Gbit card and you've got a seriously capable FreeNAS or equivalent box. There are other savings codes to be around, someone on my work slack channel said he's managed to get it down to $1170 without tax in the US!

I can't get it lower than the site price of just short of £2,000 inc VAT

If I knew more about it, I may have gone for it.

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
