Does this network card support link aggregation?

[Muramasa]

Hey guys,

 

The the company I work for are updating their server machines, and had some parts laying around that they weren't going to use in the new servers so I got the chance to purchase them. The part I am interested in is a dual 40Gbps HP infiniband network card that they have two of.

 

The model number: QLE7342-HP

 

My main question is does this card support some sort of link aggregation (Via Windows Server) to make the dual 40Gbps ports a single 80Gbps connection? and the sub question is will I have any issues running this (I'm going to assume) server grade card in a consumer board?

 

Thanks for looking.

Dont buy them unless you exactly what you are going to do with them and how.

Yeah that's why I'm posting before I do. They offered both cards for £100 and I plan putting one in my main pc and one in my server and just directly connecting them.

Bro... dont buy them unless you know exactly what you are going to do with them and how. I dont mean well ill just run a cable between them, that will work right???

That's kind of the point of this post... I wouldn't be posting about this if I could answer that question myself. The idea is inspired by this Linus video

 

He is doing the same thing that I PLAN on doing with these cards, if I find out if it's possible. Specifically (As Linus describes it) Daisy chaining two PCs, while also (If possible) combining both 40Gbps connections for a really fast 80Gbps connection.

Infiniband cards are something different as to what linus is using and I doubt u will even be able to saturate a 2gbit link with your current server.

Ok so if they cant be teamed together and comparing them to dual 10GbE Ethernet alternatives these cards are half the price and have twice the bandwidth.

 

In your opinion, do they sound like a good deal?

Its a good deal if you want to resell them. similar cards go for 70-100 dollars.

I would honestly just get 10GbE SFP+ network equipment. Infiniband would be a pain to work with.

Besides the bandwidth of 80Gb/s would be useless unless for switch uplinks.
