10 Gigabit Performance at the
Low Cost of Copper
The Intel® 10 Gigabit AT Ethernet Server
Adapter showcases Intel’s first-generation
standards-based 10BASE-T adapter in a low-
profile PCI Express* form factor. It provides
bandwidth-intensive applications highly
affordable 10 Gigabit Ethernet (GbE) network
performance with cost-effective RJ-45
connections for distances up to 100 meters.
High-speed server connectivity — once
reserved for costly, proprietary technologies
such as High Performance Computing (HPC)
clusters and grid-based computing — can
now be achieved with the standardized
connectivity of the Intel 10 Gigabit AT
Server Adapter. Intel’s adapter also provides
1000BASE-T support for gigabit connections to
legacy switches.
Next-Generation 10 Gigabit
Performance
10 Gigabit Ethernet has moved past the
early adoption stage and is rapidly becoming
mainstay for backbones within enterprise and
service provider networks. The escalating
deployments of servers with multi-core
processors and demanding applications
such as HPC, database clusters, and video on
demand are driving the need for 10 Gigabit
connections. Based on the Intel® 82598EB 10
Gigabit Ethernet Controller, this next-generation
Intel 10 Gigabit AT Server Adapter is designed
to meet the throughput requirements of
bandwidth-hungry applications.
Performance-Enhancing Features
for Multi-Core Environments
When implemented within multi-core processor
environments, the Intel 10 Gigabit AT Server
Adapter offers advanced networking
features for efficient distribution of Ethernet
workloads across CPU cores. Load balancing of
interrupts using MSI-X enables more efficient
response times and application performance.
CPU utilization can be lowered further through
stateless offloads such as TCP segmentation
offload, header replications/splitting, and Direct
Cache Access (DCA).
The Intel 10 Gigabit AT Server Adapter is
optimized for virtualized environments,
supporting multiple queues, alleviating I/O
bottlenecks between virtual machines. Virtual
Machine Device Queue (VMDq) technology
offloads data sorting and data copying from
the Virtual Machine Monitor (VMM) software
layer to the hardware, improving overall
throughput and CPU utilization on virtualized
servers. Additionally, the Intel 10 Gigabit AT
Server Adapter enables Intel® I/O Acceleration
Technology
1
(Intel® I/OAT) with support for
Intel® QuickData Technology for faster I/O
processing on the new Quad-Core and Dual-
Core Intel® Xeon® processor-based servers.
