2.1.1 Ethernet SFP+ Interface
The network ports of the ConnectX®-3 adapter cards are compliant with the IEEE 802.3 Ethernet
standards listed in Section 1.1.1, “10 and 40 Gigabit Ethernet,” on page 10. The SFP+ port has one
Tx/Rx pair of SerDes. Ethernet traffic is transmitted through the cards' SFP+ connectors.
2.1.2 PCI Express Interface
The ConnectX®-3 adapter cards support PCI Express 3.0 (1.1 and 2.0 compatible) through x4 or
an x8 edge connector. The device can be either a master initiating the PCI Express bus operations
or a slave responding to PCI bus operations.
