Intel’s family of Intel® Ethernet X520 Server Adapters with SFP+

connectivity are the most flexible and scalable Ethernet adapters

for today’s demanding data center environments. 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 the types of applications driv-

ing 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.

the Intel® Ethernet 82599 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.

To ensure maximum flexibility, Intel supports the ability to mix

any combination of the SFP+ optical modules, direct attach

copper cables, or 1000BASE-T SFP modules on the Intel Ethernet

X520 Adapters . For instance, customers can remove the optical

modules that come installed on the adapter and replace them

with an Intel® Ethernet SFP+ Optic, an SFP+ Direct Attach Copper

Cable, or a 1000BASE-T SFP module. Intel® Ethernet SFP+ Optics

are available in both short range (SR) 850 nm and long range (LR)

1310 nm options.

This enables customers to create the configuration that best

meets the needs of their data center environment.
