Energy-Efficient, 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 High Performance Computing (HPC), database clusters,
and video-on-demand are driving the need for 10 Gigabit connec-
tions. Based on the Intel® 82598EB 10 Gigabit Ethernet controller,
the next-generation Intel® 10 Gigabit XF Server Adapters are
designed to meet the throughput and latency requirements
of bandwidth-hungry applications, while offering a very low
power envelope for energy efficiency. Ideal for slot-constrained
environments, the Intel® 10 Gigabit XF Dual Port Server
Adapter provides a simplified alternative to multiple 1 Gbps
server adapters.
Performance-Enhancing Features
for Multi-Core Environments
When implemented within multi-core processor environments,
Intel 10 Gigabit XF Server Adapters offer 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).
Intel 10 Gigabit XF Server Adapters are optimized for
virtualized environments, supporting multiple queues, alleviat-
ing I/O bottlenecks between virtual machines. Virtual Machine
Device queue1 (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, Intel 10 Gigabit XF
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 XF Server
Adapters. The dedicated input/output (I/O) bandwidth of PCIe
ensures priority performance on each port 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.
Advances for Storage Over Ethernet
The fast growth in storage capacity coupled with server
virtualization has brought the need for Storage Area Network
(SAN) to the forefront. To satisfy this growing demand, Intel
10 Gigabit XF Server Adapters support iSCSI acceleration
and provide advanced features for unified storage connectivity.
Fast and reliable networked storage can be achieved via native
iSCSI support with Microsoft, Linux*, and VMware operating
systems as well as support for iSCSI remote boot.
