Overview
The new Intel® Ethernet Server Adapter
I210 builds on Intel’s history of excellence
in Ethernet products. Intel continues its
market leadership with this newest generation PCIe* GbE network adapter. Based
on the Intel® Ethernet Controller I210, this
adapter represents the next step in the
Gigabit Ethernet (GbE) networking evolution for the enterprise and data center
offering Audio-Video-Bridging (AVB) support, along with power management tech-
nologies such as Energy Efcient Ethernet
(EEE) and DMA Coalescing (DMAC).
Audio-Video Bridging (AVB)
The Intel® Ethernet Server Adapter I210
supports IEEE 802.1Qav Audio-Video
Bridging (AVB) for customers requiring
tightly controlled media stream synchronization, buffering, and reservation. The
802.1Qav is part of the AVB specication
that provides a way to guarantee bounded
latency and latency variation for time
sensitive trafc and includes:
• Timing and Synchronization for timespecic applications (802.1AS) Stream
Reservation (SR) protocol to guarantee
the resources needed for Audio/Video
(AV) streams (802.1Qat)
• Forwarding and queueing enhancements
for time sensitive streams (802.1Qav).
Performance Optimization
The Intel® Ethernet Server Adapter I210
contains four transmit and four receive
queues. These queues offer Error Correcting Memory (ECC) protection for improved
data reliability. The adapter efciently
manages packets with minimum latency
by combining parallel and pipelined logic
architectures optimized for these independent transmit and receive queues.
These queues, combined with Receive
Side Scaling (RSS) and Message Signal
Interrupt Extension (MSI-X) support,
optimize the performance on servers with
multi-core processors.

Power Savings w/EEE
Energy Efficient Ethernet Power Savings.
No Coalescing. As shown by the red line,
components have less time between DMA
calls to reach and stay in lower power.
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 that enable
enterprises to congure power options on
the adapter and more effectively manage
power consumption.
Energy Efficient Ethernet (EEE)
The Intel Ethernet Server Adapter I210
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 ap-
proximately 50% of its normal operating
power, saving power on the network port
and the switch port. When increased net-
work 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.
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.
Environmentally Friendly Design
The Intel® Ethernet Server Adapter I210
Family is low halogen1 and completely
lead-free to reduce the potential for
environmental impact. This, in combination
with power management technologies,
a unique ventilated bracket, and spacesaving design make this adapter an ideal
solution for compact workstations and
entry-level servers.
With Coalescing. With more time between
DMA calls, components can reach lower
power states and remain in them longer
2
DMA Coalescing
Another power management technology
that can reduce power on the server platform is DMA Coalescing (DMAC). Typically,
when a packet arrives at the adapter, a
DMA request is initiated in order to place
the packet into host (or server) memory.
This transaction wakes 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.
