2.1.1 Ethernet SFP+ Interface
The ConnectX
®
-2 device is compliant with the IEEE Std 802.3. The SFP+ port has one Tx/Rx pair
of SerDes.Ethernet NIC cards listed in Table 3 on page 11 based on this device provide access to
the Ethernet ports by means of SFP+ connectors.
2.1.2 PCI Express Interface
The ConnectX-2 adapter cards support PCI Express 2.0 (1.1 compatible) through an x8 edge con-
nector. The device can be either a master initiating the PCI Express bus operations or a slave
responding to PCI bus operations.
