Overview
The Intel® Ethernet Network Adapter X722 features iWARP RDMA for high
data throughput, low-latency workloads and low CPU utilization. The X722
is ideal for Software Dened Storage solutions, NVMe over Fabric
solutions and Virtual Machine Migrations acceleration.
RDMA is a host-ooad, host-bypass technology that enables a low-
latency, high-throughput direct memory-to-memory data communication
between applications over a network.
iWARP extensions to TCP/IP, standardized by the Internet Engineering
Task Force (IETF), eliminate three major sources of networking overhead:
TCP/IP stack process, memory copies, and application context switches.
Based on TCP/IP, iWARP is highly scalable and ideal for Hyper-converged
storage solutions.
The X722 is one 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 media types for broad compatibility backed
by extensive testing and validation.
• Optimization - Intelligent ooads 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 ooads, 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 ooads
such as Virtual Machine Device Queues (VMDq) and
Flexible Port Partitioning, using SR-IOV with a common
Virtual Function driver for networking trac 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.
Trac handling is ooaded to the network controller,
delivering the benets 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.
• Up to 128 VFs, each VF can support a unique and
separate data path for I/O related functions within the
PCI Express* hierarchy.
Flexible Port Partitioning (FPP)
FPP leverages the PCI-SIG SR-IOV specication. 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.
Advanced Trac Steering
Intel® Ethernet Flow Director (Intel® Ethernet FD) is
an advanced trac steering capability built into the
adapter. It consists of a large number of ow anity
lters that direct receive packets by their ows to
queues for classication, load balancing, and matching
between ows and CPU cores.
Steering trac into specic queues can eliminate
context switching required within the CPU. As a result,
Intel® Ethernet FD signicantly increases the number of
transactions per second and reduces latency for cloud
applications like memcached.
• 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
specic 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.
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, and NVGRE: These stateless ooads
preserve application performance for overlay networks,
and the network trac can be distributed across CPU
cores, increasing network throughput.
