10 Gigabit Performance
for Top-of-Rack Connections
The Intel® 10 Gigabit AF DA Dual Port Server Adapter is the
newest member of Intel's robust family of 10 Gigabit products.
Designed as a low-cost, low-power adapter, the Intel 10 Gigabit
AF DA Dual Port Server Adapter provides direct attach copper
twinaxial cable connections between servers and a top-of-rack
switch. Two ports, coupled with a low-profile PCI Express* form
factor, make this adapter ideal for slot-constrained environments.
Using direct attach copper cables compliant with the SFP + MSA
SFF-8431 specification, the Intel 10 Gigabit AD DA Dual Port
Server Adapter is well-suited for customers who require low-cost
"in-the-rack" connections of less than 10 meters between server
and top-of-rack switch.
Energy-Efficient, Next-Generation
10 Gigabit Performance
10 Gigabit Ethernet is rapidly becoming the mainstay for
backbones within enterprise and service provider networks.
Intel's 10GBASE Direct Attach adapter extends the 10 Gigabit
adoption to the server rack. The escalating deployments of
servers with multi-core processors and demanding applications
such as high-performance computing (HPC), database clusters,
virtualized servers and video on demand are driving the need
for 10 Gigabit connections in the server rack. Based on the
82598EB 10 Gigabit Ethernet controller, Intel's 10 Gigabit AF DA
Server Adapter is designed to meet the throughput and latency
requirements of bandwidth-hungry applications, while offering a
very low-power envelope for energy efficiency.
Performance-Enhancing Features
for Multi-Core Environments
As a member of the 10 Gigabit family of products, the 10GbE Direct
Attach adapter supports all of the features and functionality in
Intel's other 82598EB-based adapters. When implemented within
multi-core processor environments, the Intel 10 Gigabit AF DA
Server Adapter offers advanced networking features for efficient
distribution of Ethernet workloads across CPU cores. Load balanc-
ing 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).
Intel 10 Gigabit AF DA Server Adapters are optimized for
virtualized environments, supporting multiple queues, alleviat-
ing I/O bottlenecks between virtual machines. Virtual Machine
Device queue (VMDq) technology offloads data sorting and
1
data copying from the virtual machine monitor (VMM) software
layer to the hardware, improving overall throughput and CPU
utilization on virtualized servers. Additionally, Intel 10 Gigabit AF
DA Server Adapters enable Intel® I/O Acceleration Technology
(Intel® I/OAT) with support for Intel® QuickData for faster I/O
processing on the new Quad-Core and Dual-Core Intel® Xeon®
processor-based servers.
Conserve valuable PCI Express (PCIe*) server slots while adding
10 Gigabit Ethernet capability with Intel 10 Gigabit AF DA
Server Adapters. The dedicated input/output (I/O) bandwidth
of PCIe ensures priority performance on each port – without
bus sharing – for 10 Gigabit Ethernet connectivity, as well as a
low-profile design, which improves server throughput and rack
density at the same time. In addition, eight-lane PCIe enables
maximum bandwidth for fast and efficient data transfer. The
low-power, efficient design allows for two 10 Gigabit Ethernet
ports in a single low-profile PCIe adapter.
