Key Features
Overview
The Intel® Ethernet Adapter XXV710 delivers excellent performance for
25GbE connectivity that is backwards compatible to 1/10GbE, making
migration to higher speeds easier.
The Intel® Ethernet Adapter XXV710 is part of the Intel® Ethernet 700
Series Network Adapters. These 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 offloads 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 offloads, 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 offloads
such as Virtual Machine Device Queues (VMDq) and
Flexible Port Partitioning, using SR-IOV with a common
Virtual Function driver for networking traffic 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.
Traffic handling is offloaded to the network controller,
delivering the benefits of port partitioning with little to
no administrative overhead by the IT staff.
SR-IOV for Direct Assignment:
Adapter-based
isolation and switching for various virtual station
instances enables optimal CPU usage in virtualized
environments.
• Up to 128 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
specific VMs or guests, via a standard interface.
Intel® Ethernet Adaptive Virtual Function (Intel®
Ethernet AVF):
A virtual function driver that eases
SR-IOV hardware upgrades or changes, and preserves
base mode functionality in hardware and software.
Customers deploying mass-scale VMs or containers
for their network infrastructure now have a common
Virtual Function (VF) driver. This driver supports a
Base Mode and advanced set of features on the Intel®
Ethernet 700 Series.
Flexible Port Partitioning (FPP)
FPP leverages the PCI-SIG SR-IOV specification. 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.
Greater Intelligence and Performance for NFV
Dynamic Device Personalization (DDP) customizable
packet filtering, along with enhanced Data Plane
Development Kit (DPDK), support advanced packet
forwarding and high efficient packet processing for
both Cloud and Network Functions Virtualization (NFV)
workloads.
• 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.
Advanced Traffic Steering
Intel® Ethernet Flow Director (Intel® Ethernet FD) is
an advanced traffic steering capability built into the
adapter. It consists of a large number of flow affinity
filters that direct receive packets by their flows to
queues for classification, load balancing, and matching
between flows and CPU cores.
Steering traffic into specific queues can eliminate
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.
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 Offloads: These stateless offloads preserve
application performance for overlay networks, and the
network traffic can be distributed across CPU cores,
increasing network throughput.
