2 MELLANOX CONNECTX 2 10GbE ETHERNET NETWORK SERVER ADAPTERS HP MNPA19-XTR


Recommended Posts

The latest firmware for the switch is here https://www.ubnt.com/download/edgemax/edgeswitch-16-xg. If you google your switch and the card/cables you own it seems that the Ubiquity switch doesn't play well with active DAC cables and AUTO negotiate settings. Have you tried setting them up manually? (try to give it a static IP) Also, I always use passive cables since I would just use fiber if I had longer runs.

hey guys!!

 

im trying to do a direct connect from a windows 10 Pro machine to an unraid 6.9.2 machine. i bought 2MNPA19-XTR 10GB Mellanox ConnectX-2 cards and a 35' sfp+ cable. the windows machine sees the card just fine, its the unraid machine that im having the issues...i stop the array, look at tools/system devices, and i cant see the card. any ideas? should i post my diagnostics??

If there are not showing in Systems Devices then the system is not seeing the cards are installed. Example of my X-3

 

IOMMU group 17:			 	[15b3:1003] 05:00.0 Ethernet controller: Mellanox Technologies MT27500 Family [ConnectX-3]
IOMMU group 18:			 	[8086:15f3] 06:00.0 Ethernet controller: Intel Corporation Ethernet Controller I225-V (rev 03)

05:00.0 Ethernet controller: Mellanox Technologies MT27500 Family [ConnectX-3]

Is the PCI slots you have inserted the card in to enabled in the BIOS?

update: So i swapped slots with my HBA and that did the trick. Unraid sees the card. I setup a test network drive in windows. My 1gig connection is rock solid. now the same file to the same location but over the 10gb and windows locks up. if i get any transfer speed its in the low kb range...any thoughts?
