10/100/1000 PCI-Express* (PCIe) x1
Connectivity
The Intel® Ethernet Controller I211-AT
uses a PCIe v2.1 one lane (x1) interface
operating at 2.5 GT/s. The Intel® Ethernet
Controller I211-AT provides fully inte-
grated GbE MAC/PHY capabilities that can
be configured for either 1000 Mb/s or
10/100 Mb/s modes of operation.
Filled with Performance
Optimization Capabilities
The Intel® Ethernet Controller I211-AT
contains two transmit and two receive
queues for the single port. These queues
offer Error Correcting Memory (ECC) pro-
tection for improved data reliability. The
controller efficiently manages packets
with minimum latency by combining paral-
lel and pipelined logic architectures opti-
mized for these independent transmit and
receive queues. These queues, combined
with Receive Side Scaling (RSS) and Mes-
sage Signal Interrupt Extension (MSI-X)
support, provide a toolset for optimizing
