Question Are these PCI-E standard NICs? HP 561T? Or some proprietary connector for their servers?

The HPE Ethernet 10Gb 2-port 561T adapter is a Dual-Port 10GBASE-T adapter, featuring the Intel X540 10 GbE solution in a PCIe 2.1 compliant form factor designed for HPE ProLiant Gen8 rack and tower servers. The HPE 561T adapter delivers full Line-Rate performance across all, utilizing CAT 6A UTP cabling (Or better) with distances up to 100 meters. Providing high performance Ethernet connectivity, it is ideal for virtual server and cloud computing environments.

I believe that this is NOT NBase-T compliant or compatible at all, only 100/1000/10000 Mbit/sec (per each direction, per each port).

But would these plug into a standard DIY PC AM4 mobo's PCI-E slot (x16 sized)? Nothing "funny" going on? Just load HP/Intel X540 drivers? They're under $120 for a dual-port 10GBase-T card.

What about this dual 10GBase-X adapter for under $25 ea.??? Says it supports DAC cables, Fiber cables, doesn't mention 10GBase-T transceivers, does that have to be supported by the card/NIC processor as well, or can all 10GBase-X be converted to 10GBase-T with copper transceivers?


Edit: What's the difference between these three cards?

I have a Microtik 4-port 10GbE SFP+ switch, if I got some DAC cables (do they make 20-25 ft. ones?) that were long enough, I could connect all of my workstations with these 10GbE cards for cheap.


All the Microtik specs say are "SFP+". They don't say "10GBase-X" or "10GBase-T" signalling or whatever. According to one site that I read, different standards use different signalling.

The HPE 561T says:
"PCIe 2.1 compliant form factor; Low profile design shipping with standard height and low-profile brackets "
So, yes, it is a PCIe card, not a proprietary "mezzanine card".
Curiously, it does not say how many channels (how long) the connector is. x8?

The 561T is based on Intel X540, which predates NBase standard. Intel tends tobe solid performer.

The HP NC523SFP is based on QLogic cLOM8214.

Two of the NC523SFP can be explained with:
Model number: 593717-B21
Spare part number: 593742-1
The "HPE-IMSourcing" I have no clue about.



All SFP+ are not equal.

Intel NICs, for example, require tranceivers that look like "Intel product". Worst case that I've seen: NIC did list three supported tranceiver models, but the vendor that had assembled the card (Dell, for their server) had cut the list down to one model.

Old HP switch had SFP+. New server had too. DAC that came with server was not supported by the switch. Luckily, third-party facsimile of old HP DAC was still available and the NIC in server was ok with it.

Since DAC is "integrated solution", it has to be supported by both ends. Two tranceivers and fiber (or 10GBase-T tranceivers and Ethernet copper) is more flexible.

Found on https://www.completeconnect.co.uk/direct-attach-copper-dac-cables-sfp-sfp28/
"There are 2 versions of SFP+ Direct Attach Copper Cable; passive and active. Passive DAC Cables enable connection up to 12m. Active DAC cables have an increased distance (to 15m) and also have a reduced size cable diameter. Note – Some equipment brand will only accept active DAC cables."
