PCI-SIG SR-IOV is a mechanism for devices 
to advertise their ability to be directly 
assigned to multiple virtual machines. 
SR-IOV enables the partitioning of a 
PCI Express* (PCIe) function into many 
virtual interfaces for the purpose of 
sharing the resources of a  PCIe device 
in a virtual environment. These virtual 
interfaces are called Virtual Functions. 
Each virtual function can support a unique 
and separate data path for I/O-related 
functions within the PCIe hierarchy. Use 
of SR-IOV with a networking device, for 
example, enables the bandwidth of a 
single port (function) to be partitioned 
into smaller slices that can be allocated 
to specific VMs, or guests, via a standard 
interface.
The Intel Ethernet X520 family of 
adapters delivers the same functionality 
and throughput as ten dual-port, one 
gigabit adapters, saving cost, power, and 
complexity. For more information on

unified Networking and Storage
The family of Intel Ethernet X520 
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 adapters offer 
FCoE hardware acceleration to provide 
performance comparable to FC HBAs. The 
adapters support Data Center Bridging, 
also known as Converged Enhanced 
Ethernet (CEE), which enables customers 
to configure traffic classes and priorities 
to deliver a lossless Ethernet fabric. 
An Intel Ethernet Converged Network 
Adapter X520 reduces TCO by eliminating 
redundant fabrics and saves the cost of 
expensive FC HBAs and FC switch ports.
Support for iSCSi
The adapters provide complete support 
for proven native OS and VMM iSCSI 
initiators as well as iSCSI boot. Historically, 
CRC32C computation has degraded 
system performance, but 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 Intel Ethernet family of X520 
adapters do it all: 10 Gigabit LAN, FCoE, 
and iSCSI; truly delivering on the promise  
of unified networking.
reliable performance
The family of X520 adapters includes a 
number of advanced features that enable 
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 adapter enables 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.
designed for Multi-core processors
Support for technologies such as 
multiple queues, receive-side scaling, 
multiple MSI-X vectors, and Low Latency 
Interrupts enable the X520 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 adapters deliver ultimate flexibility 
and scalability.
