Hi Anand,
On http://www.mellanox.com/related-docs/prod_adapter_cards/ConnectX3_EN_Card.pdf I can see following statement.
* IEEE Std 802.3ae 10 Gigabit Ethernet
* Interoperable with 10/40GbE switches
On http://www.mellanox.com/related-docs/user_manuals/Mellanox_approved_cables.pdf I can see that 40GbE ConnectX-3 Cards (ex. MCX314A-BCBT) are suitable with following hybrid cables.
* MC2609130-001
* MC2609130-003
* MC2609125-005
But, I don't have any idea how to change the 1x 40GbE mode to 4x 10GbE mode on those cards. Do you have other understanding of statement on above files?
Best regards,
