Question Add-in 2.5Gbit adapter

BTRY B 529th FA BN

BTRY B 529th FA BN

Lifer
I have an old Intel Gigabit CT adapter nic but I'm looking for a 2.5Gbit adapter that can do 8 Rss queues. Anyone know of any good adapters to do the job?

Thanks
 
I don't kno about the "8 RSS queues" thing, but you can get discrete 2.5gbit PCI-E NICs, either with the RealTek or Intel chipsets, at Amazon for $25-30. Intel-based 2.5gbe NICs will take more careful searching.

Pretty sure even the latest intel consumer 2.5Gbps NIC supports at most 4 queues.

I assume you'd need a server NIC for more queues, and probably a lot of CPU cores to feed it.
 
Not even sure why 8 RSS queues minimum is a requirement. Remember, OP is also the same guy that needed to edit the registry to make sure that all of his interrupts were "Message Signaled".

Either OP plays at the highest possible frame rate capable on PC hardware, or he has "latency OCD".

Kind of like a "gamer" friend of mine, that swore up and down that his experience was better when he unplugged his router to plug his cable modem directly into his PS3. Maybe, but really, going to go to that hassle every time that you want to play online, and forgoe voice-chat on PC, looking things up, etc.?

Edit: I should add, I'm being a bit overly harsh picking on OP about his "PC OCD". And Message Signalled should be the default interrupt type on modern ACPI systems. (It's mode for the IOAPIC in the CPU, and maybe corresponding in the chipset.)

Don't know why OP need so many queues processed by 8 CPUs or 8 cores? Network packets handled by several prcoessors/cores not necessarily will be more efficeint if all you need is a single CPU/core.

The AQN107 chipset according to the Q&A section supports the 8 queues you're looking for. I use their 5GE 4-port card from QNAP for my server/router and it works well. The above though is a 10GE/5GE/2.5GE/1GE/100MB card so i t would fit the requitement and then some.

For the Intel i225 based NICs, you need to ensure you are getting the B-stepping which fixed a bug with interpacket gap handling that caused it to not run at full speed when connected to some switches.

Is there a serial code that would indicate the B-stepping? I have this bookmarked but don't know if it B-stepping.


Just want to say thanks to everyone who posted! I appreciate all the help

From a review on that product page

The QXG-2G1T-I225 cards I received were PCB rev 1.2 and the IC is marked SLNNH, Intel's product code for "I225-LM v3" which is the current B3 stepping
