10 gigabit Ethernet server adapters provide ultimate flexibility and scalability for cloud deployments
system design thereby reducing complex-
ity and cost, allowing data centers to scale 
out more effectively. By publishing the 
designs and specifications of this low-
power, low-cost hardware, it can reduce 
the cost of infrastructure for businesses 
large and small.

Today’s data centers depend on the mul-
tiprocessing, high performance capability 
of servers to increase system throughput, 
responsiveness, and reliability through 
the introduction of additional hardware 
threads, CPUs, or cores.  But in a multi-
processing environment, it is essential to 
ensure a coordinated affinity of protocol 
processing and network applications 
on the same target cores. This affinity 
significantly reduces contention for shared 
resources, minimizes software synchro-
nization overheads between cores, and 
enhances cache efficiency.
Receive Side Scaling (RSS) resolves the 
single-processor bottleneck by enabling 
the receive side network load from a net-
work adapter to be shared across multiple 
cores. RSS enables packet receive-pro-
cessing to scale with the number of avail-
able cores. However, RSS has a limitation. 
it cannot steer an incoming network flow 
to the same core where the application 
process resides. RSS does not maintain the 
Traffic Flow>Core (Application) relation-
ship. If an application is running on one 
core, while RSS has scheduled receive 
Overview
The best-selling Intel® Ethernet Converged 
Network Adapter X520 Series is known 
for its high performance, low latency, 
reliability, and flexibility. The addition of 
the Intel® Ethernet Server Adapter X520 
Series for Open Compute Project (OCP) to 
the family delivers the X520 capabilities 
in an Open Compute Project (OCP) form 
factor. 
The Intel® Ethernet Server Adapter X520 
Series for Open Compute Project (OCP) 
delivers a proven, reliable solution for de-
ployments of Ethernet for high bandwidth, 
low cost, 10GbE network connections.  
Increased I/O performance with Intel® 
Data Direct I/O Technology (Intel® DDIO) 
and support for intelligent offloads make 
this adapter a perfect match for scaling 
performance on Intel® Xeon® processor E5/
E7 based servers.
Powered by the Intel® 82599 10 Gigabit 
Ethernet Controller, the Intel® Ethernet 
Server Adapter X520 Series for OCP 
addresses the demanding needs of the 
next-generation data center by providing 
unmatched features for virtualization and 
proven, reliable performance. The Intel® 
82599 10 Gigabit Ethernet Controller is 
the industry standard for 10 GbE, making 
it the most popular 10GbE controller on 
the market today.
The Open Compute Project (OCP) is a Face-
book* initiative to openly share custom 
data center designs to improve both cost 
and energy efficiency across the industry. 
The OCP uses a minimalist approach to
