10 Gigabit Ethernet PCI Express Server Adapter is designed for server and high-end
equipment, deploy multiple network and deploy the ideal solution of critical Web
applications and the environment in high performance servers. This server adapter
can easily integrate any PCI Express X8 into 10 Gigabit network. And optimized
for performance, the system’s I/O is no longer the bottleneck of high-end network

applications. This server adapter is based on Intel 82599ES Ethernet controller, with two
fully integrated Gigabit Ethernet Media Access Control (MAC) and XAUI ports. In addition
to managing Ethernet MAC and PHY layer functions, this controller manage PCI-E packet
traffic through its transaction, link, physical and logical layer. The controller can share
tasks for the host through hardware acceleration, such as TCP / UDP / IP checksum
calculation and TCP segmentation.
This new Ethernet X520 Server Adapters are the most flexible and scalable Ethernet
adapters for today’s demanding data center environments. Data center networks are
being pushed to their limits. 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 connections.
Customers require flexible and scalable I/O solutions to meet the rigorous requirements of
running mission-critical applications in virtualized and unified storage environments.
Powered by the third-generation 10 GbE network controller, the Intel Ethernet 82599ES
10 Gigabit Ethernet Controller, the X520 server adapter family addresses the demanding
needs of the next-generation data center by providing unmatched features for
virtualization, flexibility for LAN and SAN networking, and proven, reliable performance.
2 .2 . Be st C hoi ce fo r Vi r tua l i z ation
The explosive growth in virtualization is leading to an increasing demand for network
performance. With more Virtual Machines (VMs) running on each multi-core server,
networking traffic is dramatically increased with each VM competing for available
I/O bandwidth. Intel’s new family of Intel Ethernet X520 Server Adapters addresses
networking bottlenecks in virtualized environments. These new adapters enable networkintensive applications to achieve the performance expected in a virtualized environment.
The Ethernet X520 family of server adapters provides the best networking performance
available in the industry, whether the physical port is configured in an emulation mode
using the virtual switch in the Virtual Machine Monitor (VMM), or is directly assigned to
a virtual machine. In the emulation mode, Intel’s I/O technology, Virtual Machine Device
queues 1 (VMDq) optimizes network performance by offloading data sorting and copying
from the software Virtual Switch in the VMM to the Intel Ethernet 82599ES 10 Gigabit
Controller. This configuration is best suited for a large number of VMs running standard
applications that have limited bandwidth and latency requirements.
The Ethernet X520 family of server adapters delivers the same functionality and
throughput as ten dual-port, one Gigabit adapters, saving cost, power, and complexity.
2 .3 . U ni f i e d Ne t wo r ki ng a nd S torag e
The family of Intel Ethernet X520 server adapters lowers your data center total cost of
ownership (TCO) by providing the ability to route LAN and SAN traffic over a single fabric.
Support for Fiber Channel over Ethernet (FCoE) – FCoE encapsulates Fiber Channel
frames over standard Ethernet networks, enabling Fiber Channel to take advantage of 10
GbE networks while preserving its native protocol. The X520 server adapters offer FCoE
hardware acceleration to provide performance comparable to FC HBAs. The new server

adapters support Data Center Bridging, also known as Converged Enhanced Ethernet
(CEE), which allows customers to configure traffic classes and priorities to deliver a
lossless Ethernet fabric. An Intel Ethernet X520 server adapter reduces TCO by eliminating
redundant fabrics and saves the cost of expensive FC HBAs and FC switch ports.
Support for iSCSI – The server adapters provide complete support for proven native OS
and VMM iSCSI initiators as well as iSCSI boot. now with the CRC instruction set included
in the latest Intel Xeon processors, CRC validation is possible with minimal impact to
network throughput while delivering superior data integrity.
The new Ethernet family of X520 server adapters do it all: 10 Gigabit LAN, FCoE, and iSCSI;
truly delivering on the promise of unified networking.
2 .4 . Re l i a bl e Pe r for m a nce
The family of X520 server adapters include a number of advanced features that allow it to
provide industry-leading performance and reliability.
Security Optimizations – The adapters support IPsec offload for Microsoft’s Network
Access Protection (NAP), Active Directory,* and future security capabilities in Windows* 7.
An X520 server adapter allows customers to run a secure network environment without
sacrificing performance.
PCIe v2.0 (5 GT/s) – PCIe v2.0 (5 GT/s) support enables customers to take full advantage
of 10 GbE by providing a maximum of 20 Gbps bi-directional throughput per port on a
single dual port card. 10 Gigabit Ethernet controller along with Intel Xeon 5500 series
processor servers deliver the performance that demanding applications require.
Designed For Multi-core Processors – Support for technologies such as Intel QuickData,
multiple MSI-X vectors, and Low Latency Interrupts allow the X520 server adapters to
provide high-performance, 10 Gigabit connectivity in multi-core server blades. These
technologies distribute network processing across multiple CPU cores, improving overall
performance. For today’s demanding virtualized data center environments, the new
family of X520 server adapters deliver ultimate flexibility and scalability.
