Overview
The new Intel® Ethernet Server Adapter
I350 family builds on Intel’s history of
excellence in Ethernet products. Intel
continues its market leadership with this
new generation of PCIe* GbE network
adapters. Built with the bridgeless Intel®
Ethernet Controller I350, these adapters
represent the next step in the Gigabit
Ethernet (GbE) networking evolution
for the enterprise and data center by
introducing new levels of performance
through industry-leading enhancements
for both virtualized and iSCSI Unied
Networking environments. This new
family of adapters also includes new
power management technologies such as
Energy Efcient Ethernet (EEE) and DMA
Coalescing (DMAC).
Flexible I/O Virtualization
The Intel® Ethernet Server Adapter
I350 family includes Intel® Virtualization
Technology for connectivity (Intel® VT-c)
to deliver I/O virtualization and Quality
of Service (QoS) features designed
directly into the controller on the
adapter. I/O virtualization advances
network connectivity models used in
today’s servers to more efcient models
by providing Flexible Port Partitioning
(FPP), multiple Rx/Tx queues, and oncontroller QoS functionality that can be
used in both virtual and non-virtual server
deployments.
By taking advantage of the PCI-SIG
SR-IOV specication, Intel® Ethernet
products enable Flexible Port Partitioning
(FPP). With FPP, virtual controllers can
be used by the Linux* host directly and/
or assigned to virtual machines. With
this port partitioning, administrators can
create up to eight dedicated connections
on a single Ethernet port for use in baremetal and virtualized server deployments.
In a bare-metal Linux server, host
processes can be assigned to dedicated
network resources to provide trafc
isolation and balanced bandwidth
allocation.
In a virtualized environment, a VM can be
assigned to a virtual controller to reduce
the CPU overhead seen when using
a software-based network bridge by
ofoading network trafc management to
the controller.
Energy Efficient Ethernet reduces the controller

power to approximately 50% of its normal
operating level.

Scalable iSCSI Performance
An Intel Ethernet Server Adapter
I350 with native iSCSI initiators built
into Microsoft* Windows*, Linux*, and
VMware* ESX platforms provides a
simple, dependable, cost-effective
way to connect to iSCSI SANs. These
native initiators are broadly tested
using multiple generations of operating
systems, storage systems, and OS
tools to help ensure reliability and
ease of use. Standardizing on Intel®
Ethernet Adapters for iSCSI enables
administrators to use a single initiator,
TCP/IP stack, and a common set of
management tools and IT policies.
In addition, Intel® Ethernet Server
Adapters include a number of hardware
features designed to accelerate iSCSI
trafc and enhance data processing.
For example, TCP segmentation ofoad
and checksum ofoad capabilities
help reduce processor usage, increase
throughput, and deliver exceptional
iSCSI performance. Finally, using native
OS initiators, an Intel Ethernet Server
Adapter I350 supports the CRC-32 digest
instruction set included with Intel® Xeon®
processor products, which improves
transmission reliability and delivers an
enterprise-class iSCSI solution.
Power Management Technologies
Today, companies everywhere are
looking for ways to decrease energy
consumption across the enterprise
to reduce costs and environmental
impact, while at the same time
solving increasingly important power
density challenges. That’s why Intel
has introduced new, advanced Power
Management Technologies (PMTs)
with the Intel Ethernet Server Adapter
I350 family that enable enterprises to
congure power options on the adapter
and more effectively manage their power
consumption.
Energy Efficient Ethernet (EEE)
The Intel Ethernet Server Adapter I350
family supports the IEEE802.3az Energy
Efcient Ethernet (EEE) standard so that,
during periods of low network activity,
EEE reduces the power consumption of
an Ethernet connection by negotiating
with a compliant EEE switch port to
transition to a low power idle (LPI)
state. This reduces the controller power
to approximately 50% of its normal
operating power, saving power on the
network port and the switch port. As
soon as increased network trafc is
detected, the controller and the switch
quickly come back to full power to handle
the increased network trafc. EEE is
supported for both 1000BASE-T and
100BASE-TX.
DMA Coalescing
Another power management technology
that can reduce power on the server
platform is DMA Coalescing (DMAC).
Typically, when a packet arrives at a
server, DMA calls are made to transfer
the packet within the server. These calls
wake up the processor, memory and
other system components from a lower
power state in order to perform the tasks
required to handle the incoming packet.
Based on the congurable DMAC
settings, incoming packets are buffered
momentarily before any DMA calls are
made. This enables the controller to
intelligently identify opportunities to
batch multiple packets together so that
when components are wakened from
lower power states they can efciently
handle the batched packets at the same
time. This enables platform components
to remain in lower power states longer,
which can dramatically reduce platform
energy consumption. DMAC synchronizes
DMA calls across all controller ports to
ensure maximum power savings.
Software Tools and Management
Intel® Advanced Network Services (Intel®
ANS) include new teaming technologies
and techniques such as Virtual Machine
Load-Balancing (VMLB) for Hyper-V
environments. Today, Intel ANS includes
a variety of teaming congurations for
up to eight adapters, support for mixed
vendors server adapters teaming and
includes support for 802.1q VLANs,
making Intel ANS one of the most capable
and comprehensive tools for supporting
server adapter teaming.
Additionally, Intel® PROSet for Windows*
Device Manager and PROset CL extends
driver functionality to provide additional
reliability and Quality of Service features
and conguration.
