Intel® Ethernet Converged Network Adapter  XL710

 

With Support for QSFP+ Connections 
Network Connectivity

 

 

 

 

 

The Intel® Ethernet CNA XL710 delivers an innovative new 
architecture that has been designed to meet the needs

 

of customers who require flexible 40GbE and 10GbE 
interfaces. With the unique ability to be configured for

 

4 x 10GbE, 1 x 40GbE, or 2 x 40GbE, this family of adapters

 

offers the agility needed in today’s data centers.

 

 

Network virtualization is the next big trend in creating an 
agile data center. The family of Intel® Ethernet CNA XL710s 
are ready to help you take that next step.

 

: These stateless offloads 

preserve application performance for overlay networks. 
With these offloads it is possible to distribute network 
traffic across CPU cores.

 

At the same time the Intel® Ethernet CNA XL710 offloads 
LSO, GSO, and checksum from the host software reducing 
CPU overhead.

 

 

With Intel® Virtualization Technology (Intel® VT), the Intel® 
Ethernet CNA XL710 family delivers outstanding I/O perfor- 
mance in virtualized server environments. They reduce I/O 
bottlenecks by providing intelligent offloads for networking 
traffic per Virtual Machine (VM), enabling near-native 
performance and VM scalability. The host-based 
virtualization technologies supported by Intel® VT include:

 

• VMDq for Emulated Path: Adapter-based VM Queue

 

sorting enabling efficient hypervisor-based switching

 

• SR-IOV for Direct  Assignment:  Adapter-based  isolation 

and switching for various virtual station instances enabling 
optimal CPU usage in virtualized  environments

 

Additionally, the Intel® Ethernet CNA XL710 provides 
Virtual Bridging

(VB) support that delivers both host-side 

and switch-side control and management of virtualized I/O 
as well as the following modes of virtualized  operation:

Intel® Ethernet FD is an advanced traffic steering capability 
built into the Intel® Ethernet CNA XL710. It consists of a 
large number of flow affinity filters that direct received 
packets by their flows to queues for classification, load 
balancing, and matching between flows and CPU cores. It 
eliminates context switching required within the CPU.

 

As a result, Intel® Ethernet FD significantly increases the 
number of transactions per second and reduces latency for 
cloud applications like Memcached.

 

 

The Intel® Xeon® processor family has demonstrated 
increased computing performance and increased integration 
of key server subsystems generation after generation.

 

To offload is to leverage the ever-escalating computing 
power of the Intel® Xeon® processor where appropriate and 
implement complementary accelerations in the network 
controller—this is what Intel refers to as “intelligent 
offloads.” By employing a balanced hybrid of compute and 
offload, intelligent offloads are able to achieve the optimized 
point of performance and efficiency. This is most notably 
observed in the following usage models:

 

• TCP Stateless Offloads: Demonstrates leading performance 

vs. TOE solutions without restricting feature usage (TOE 
usage usually requires that key features be disabled). 
Supported stateless offloads include Checksum, TSO, 
VMDq, and RSS.

 

• Host iSCSI Initiator: Provides exceptional 

performance without the need for full-offload 
HBA methods.

 

• Flow Classification: Routing data flows  across

 

multiple consumers and connections.

 

 

Power efficiency is critical to IT specialists as energy

 

consumption is a real OpEx concern.

 

• Lowest Power Consumption: The new generation of Intel® 

Ethernet CNA XL710s are power misers. They deliver 
double the throughput with only half the power of the 
previous Intel® Ethernet Converged Network Adapter X520 
generation.

 

 

Converging data and storage onto one fabric eliminates 
the need for multiple adapters, cables, and switches.

 

Furthermore both 10GbE and 40GbE provides

 

the bandwidth to converge these multiple fabrics. A key 
capability that makes all this possible is traffic class separa- 
tion provided by Data Center Bridging (DCB)—providing a 
one-wire solution with virtual pipes for the different classes of 
traffic:

 

• Data: Best effort delivery of standard LAN  traffic

 

• Storage: Lossless network for  iSCSI

 

• Management: Guaranteed connectivity of data center 

IP management
