Overview

Simplify technology transitions with the Intel® Ethernet Network Adapter X710-T2L and X710-T4L. Autonegotiation between port

speeds provides maximum exibility in dual and quad-port 10GBASE-T congurations. These low-power adapters also support Energy Ecient Ethernet to eciently reduce power consumption during periods of low

data activity.

The X710-T2L and X710-T4L are part of the Intel® Ethernet 700 Series, the foundation for server connectivity; providing broad interoperability, critical performance optimizations, and increased agility for Communications, Cloud, and Enterprise IT network solutions.

• Interoperability - Multiple speeds and media types for broad

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.

drivers for scalable packet processing.

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 with a common

Virtual Function driver for networking trac per Virtual

Machine (VM), enabling near-native performance and VM scalability. Host-based features supported include:

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 per port bandwidth across multiple dedicated network resources, ensuring balanced QoS by giving each assigned virtual

controller equal access to the ports bandwidth.

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

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.

• 128 virtual functions (VFs), each VF can support a unique and separate data path for I/O related 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

specic VMs or guests, via a standard interface.

Intel® Ethernet Adaptive Virtual Function (Intel® Ethernet AVF): Customers deploying mass-scale VMs

or containers for their network infrastructure now have a common VF driver. This driver eases SR-IOV hardware upgrades or changes, preserves base mode functionality in hardware and software, and supports an advanced set of features in the Intel® Ethernet 700 Series.

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 and Cloud deployments

Dynamic Device Personalization (DDP) customizable packet filtering, along with enhanced Data Plane Development Kit (DPDK), support advanced packet forwarding and highly-efficient packet processing for both Cloud and Network Functions Virtualization (NFV) workloads.

• DDP enables workload-specic optimizations, using the programmable packet-processing pipeline. Additional protocols can be added to the default set

to improve packet processing eciency that results in

higher throughput and reduced latency. New protocols

can be added or modied on-demand, and applied at runtime using Software Dened Firmware or APIs,

eliminating the need to reset or reboot the server. This not only keeps the server and VMs up, running, and computing, it also increases performance for Virtual

Network Functions (VNFs) that process network trac that is not included in the default rmware.

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

Advanced Trac Steering

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

advanced trac steering capability. Large numbers of ow anity lters 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.
