Overview

Migration to 10GbE is dramatically simplied with backward compatibility

for existing nework infrastructure. Auto-negotiation between 100 Mb/s, 1GbE, and 10GbE provides the necessary backwards compatibility that most customers require for a smooth transition and easy migration to

10GbE. 10GBASE-T switches can now be aordably added at any time to experience the full benets of 10GbE.

10GBASE-T is the easiest and most versatile 10GbE interface that can be

deployed anywhere in the data center. Its exible reach from 1 meter to

100 meters support the latest network architectures including Top of Rack (ToR), middle of Row (MoR), and End of Row (EoR).

Intel® Ethernet 700 Series Network Adapters are the foundation for server connectivity, providing broad interoperability, critical performance optimizations, and increased agility for Telecommunications, Cloud, and Enterprise IT network solutions.

• Interoperability - Multiple speeds and media types for broad compatibility backed by extensive testing and validation.

• Optimization - Intelligent ooads and accelerators to unlock network

performance in servers with Intel® Xeon® processors.

• Agility - Both Kernel and Data Plane Development Kit (DPDK) drivers for scalable packet processing.

Built on more than 35 years of continuous Ethernet innovations, the Intel® Ethernet 700 Series delivers networking performance across a wide

range of network port speeds through intelligent ooads, sophisticated

packet processing, and quality open source drivers.

All Intel® Ethernet 700 Series Network Adapters include these feature-rich technologies:

Flexible and Scalable I/O for Virtualized Infrastructures

Intel® Virtualization Technology (Intel® VT), delivers outstanding I/O performance in virtualized server environments.

I/O bottlenecks are reduced through intelligent ooads

such as Virtual Machine Device Queues (VMDq) and Flexible Port Partitioning, using SR-IOV for networking

trac per Virtual Machine (VM), enabling near-native

performance and VM scalability. Host-based features supported include:

VMDq for Emulated Path: VMDq, enables a hypervisor to represent a single network port as multiple network

ports that can be assigned to the individual VMs. Trac handling is ooaded to the network controller, delivering the benets of port partitioning with little to no administrative overhead by the IT sta.

SR-IOV for Direct Assignment: Adapter-based isolation and switching for various virtual station instances enables optimal CPU usage in virtualized environments.

• With up to 128 Virtual Functions (VF)s, each VF can support a unique and separate data path for I/Orelated functions within the PCI Express* hierarchy.

• Use of SR-IOV with a networking device, for example, allows the bandwidth of a single port (function) to be partitioned into smaller slices that can be allocated to specific VMs or guests, via a standard interface.

Enhanced Network Virtualization Overlays (NVO)

Network virtualization has changed the way networking is done in the data center, delivering accelerations across a wide range of tunneling methods.

VXLAN, GENEVE, NVGRE, MPLS, and VXLAN-GPE with NSH Ooads: These stateless ooads preserve application performance for overlay networks, and the

network trac can be distributed across CPU cores,

increasing network throughput.

Greater Intelligence and Performance for NFV

A combination of hardware and software acceleration features, such as Application Device Queues (ADq) and Dynamic Device Personalization (DDP), enable

customizable packet ltering. The acceleration features,

along with enhanced Data Plane Development Kit (DPDK), support advanced packet forwarding and high

ecient packet processing for both Cloud and Network

Functions Virtualization (NFV) workloads.

• ADq is a fast queuing and signaling technique for high-speed I/O that improves performance and limits performance jitter.

• DDP enables a method to change the packet processing pipeline by applying a profile package to the Intel® Ethernet 700 Series Network Adapter at runtime—resulting in improvements in throughput, latency and reduced CPU loads.

• DPDK provides a programming framework for Intel® processors and enables faster development of high-speed data packet networking applications.

Flexible Port Partitioning (FPP)

FPP leverages the PCI-SIG SR-IOV specication. Virtual

controllers can be used by the Linux* host directly and/or assigned to virtual machines.

• Assign up to 63 Linux host processes or virtual machines per port to virtual functions.

• Control the partitioning of 10GbE bandwidth across multiple dedicated network resources, ensuring balanced QoS by giving each assigned virtual controller equal access to 10Gbs of bandwidth.

Network administrators can also rate limit each of these services to control how much of the 10GbE pipe is available to each process.

Advanced Traffic Steering

Intel® Ethernet Flow Director (Intel® Ethernet FD) is

an advanced trac steering capability built into the adapter. It consists of a large number of ow anity lters that direct receive packets by their ows to queues for classication, load balancing, and matching between ows and CPU cores.

Steering trac into specic queues can eliminate

context switching required within the CPU. As a result,

Intel® Ethernet FD signicantly increases the number of

transactions per second and reduces latency for cloud applications like memcached.
