Product of Israel and FDR. Are these HP-rebranded Mellanox ConnectX-3?

I recently got some CX2 QDR cards because they were a lot cheaper than the CX3s and I figured QDR will be plenty fast for home use. I also realized I'm not sure what the difference is between CX2 and 3, but folks here seem to really like the CX3s for whatever reason.

this is quite good, cx-3 can do sr-iov and is pcie3.
so higher bandwidth/total throughput especially on the dual-port where even pcie3 x8 is the bottleneck.

So are these equivalent to the MCX354A-FCBT or the MCX353A-QCBT?

Is there something wrong with that eBay seller? All his listings are either "freight" shipping or list stuff like "$200 flat rate" shipping for items like a headset. Seems fishy.

I pinged them to inquire about shipping. Their warehouse is "looking into it"

Same here. Received "[p]lease be patient as our warehouse gathers the information needed to quote you for shipping" a few hours ago.

That is good to hear. I'll buy some from him if he can figure out the shipping cost.

I've got a pair of older ConnectX-2 QDR dual-port cards cards with full height brackets that I could swap for these. Hopefully shipping for a pair of them is reasonable!

Nothing wrong with the seller. Be patient... Just take long time to respond with actual shipping costs. Many of us here bought Hitachi 2.5" SAS spinners from them and one of the best packaging better than some sellers do for new drives.
I think freight shipping gives them more flexibility time window after order is paid.

They are online and responding to ebay questions super-fast today. Just got 4 of 'em and had him ship on my fedex account so I get them Monday.

The seller did get back to me with a shipping price (~$20 for fedex to the midwest) so I'm going to go ahead and order a batch from them. Thanks everybody that chimed in with their experiences with the seller.
