"Despite the price, it is important that Dell is offering an AQuantia-based NIC designed for 2.5G and 5 G infrastructure because it means that the large PC supplier sees promise in 2.5G/5G networks."
That is never going to happen if they are charging $277 for it.
It's good to see that some higher speed networks are starting to become available which are backwards compatible (assuming compatible wiring of course) at a reasonable price. At $100.00 per card (if you can get them at that price) that's actually quite affordable.
I agree. I just bought a 2 pack of HP branded 10G Mellanox SFP+ nics ($45 for both). I don't want to bother with the switch yet, so I just directly connected them with a passive twinax cable. I only needed 6 feet, but up to 5 meters passive works fine. I now have a really cheap 10G directly connected NAS for my main workstation.
It's a little ITX board, so I can only add one. But if it had dual SFP ports, or I had an ATX board with more slots, I can build myself a cheap little switch / router directly on the NAS.
SFP+ is fine and neat, but you dare to expand just a little, and you have to sell both yours and neighbours kidneys. I'd prefer to buy RJ45 SFP+ transcievers and use existing copper infrastructure, until affordable full 10G switches show up. For now I'm using myself 24+4 1G/10G switch that I grabbed on ebay for ~$170, and it's absolutely easy to expand. But 10G RJ45 cards did cost me an arm and a leg. I paid $300 for Intel X540T2 for NAS, dammit!
Actually, no. SFP+ is not that expensive anymore. 16 port switch with SFP+: https://mikrotik.com/product/crs317_1g_16s_rm can be had for about $300 new from resellers. The patch cables and SFP+ modules are cheap as hell from either fiberstore or just random ebay sellers.
When copying to a USB 3.0-3.1 SSD USB and then copyong it again to the 2nd pc and it's still miles faster than direct ethernet to ethernet connection something fishy is going on.
They really want to keep 2.5-5G ethernet as enterprise with the huge premium attached, like fiber internet 1:1 years ago.

You could have the fattest pipe around, and you bandwidth would be easily exceeded by a station-wagon full of tapes.

They should be less than $40. This is basic networking that's standard stuff. Come on oems stop constantly ripping people off.hechacker1 - Saturday, August 19, 2017 - link
