Did you know?
The 40 Gb Ethernet solution that is offered by Flex System can deploy more workloads per server without running into I/O bottlenecks. If there are failures or server maintenance, clients can move their virtual machines much faster by using 40 Gb interconnects within the chassis.
The 40 GbE switch and adapter are designed for low latency, high bandwidth, and computing efficiency for performance-driven server and storage clustering applications. They provide extreme scalability for low-latency clustered solutions with reduced packet hops.

Mellanox ConnectX-3 and EN6132 2-port 40Gb Ethernet Adapters for Flex System 2
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 802.1Qaz Enhanced Transmission Selection (ETS)
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
