Features and specifications
The adapters have the following features and specifications:
Based on Mellanox ConnectX-3 technology
PCI Express 3.0 x8 host-interface
Two 40 Gb Ethernet ports that can operate at 10 Gbps or 40 Gbps speeds
CPU offload of transport operations
RDMA over Converged Ethernet (RoCE).
TCP/UDP/IP stateless offload.
TCP/UDP/IP checksum offload
TCP Large Send or Giant Send offload for segmentation
Receive Side Scaling (RSS)
End-to-end quality of service (QoS) and congestion control
Support for IEEE 802.1p and IP DSCP/TOS traffic processing based on the class of service.
Support for 802.3x flow control.
Congestion Notification (IEEE Std 802.3Qau) limits the transmission rate to avoid frame
losses in case of congestion in the network.
Priority-Based Flow Control (PFC) (IEEE 802.1Qbb) extends 802.3x standard flow control to
allow the switch to pause traffic based on the 802.1p priority value in each packet’s VLAN
tag.
Enhanced Transmission Selection (ETS) (IEEE 802.1Qaz) provides a method for allocating
link bandwidth based on the 802.1p priority value in each packet’s VLAN tag.
Hardware-based I/O virtualization
Jumbo frame support (up to 10 KB)
802.1Q VLAN tagging
NIC teaming and failover (static and LACP)
Support for Wake on LAN (WoL)
Supported standards
The adapters support the following Ethernet standards:
IEEE 802.1p Class of Service (CoS) prioritization
IEEE 802.1Q Tagged VLAN
IEEE 802.1Qbb Priority-Based Flow Control (PFC)

IEEE 802.3ad Link Aggregation Control Protocol
IEEE 802.3ae 10GBASE-KR backplane 10 Gb Ethernet
IEEE 802.3ba 40GBASE-KR4 backplane 40 Gb Ethernet
IEEE 802.3Qau Congestion Notification
IEEE 802.3x Full-duplex Flow Control
