Exciting New Data Center Usage 
Models
More than simply a 10x increase in per-
formance, with 10 GbE there are exciting 
new usage models that are now possible, 
including Unied Networking (iSCSI, FCoE 
and LAN), Virtualization (VMDq and SR-
IOV), and now, Flexible Port Partitioning 
(FPP).
Flexible I/O Virtualization
Virtualization changes the way server 
resources are deployed and managed by 
running multiple applications and operat-
ing systems independently on a single 
server.
The Intel Ethernet Converged Network 
Adapter X540-T2 includes Intel® Virtual-
ization Technology for connectivity (Intel 
VT-c) to deliver I/O virtualization and 
Quality of Service (QoS) features designed 
directly into the X540 controller on the 
adapter. Intel® I/O virtualization advances 
network connectivity models used in 
today’s servers to more efcient models 
by providing FPP, multiple Rx/Tx queues, 
and on-controller QoS functionality that 
can be used in both virtual and non-virtual 
server deployments.
Flexible Port Partitioning (FPP)
By taking advantage of the PCI-SIG SR-IOV 
specication, Intel Ethernet products en-
able FPP. With FPP, virtual controllers can 
be used by the Linux* host directly and/or 
assigned to virtual machines. FPP allows 
you to use the functionality of SR-IOV 
to assign up to 63 processes per port to 
virtual functions in Linux. This enables 
an administrator to partition their 10 GbE 
bandwidth across multiple processes, 
ensuring a QoS by giving each assigned 
process equal bandwidth. Network admin-
istrators may also rate-limit each of these 
services to control how much of the 10 
GbE pipe is available to each process.
Unified Networking
Unied Networking solutions on the new 
Intel® Ethernet Converged Network Adapt-
er X540-T2 let you combine the trafc of 
multiple data center networks like LAN 
and SAN onto a single efcient network 
fabric. You now have the choice of NFS, 
iSCSI, or Fibre Channel over Ethernet 
(FCoE) to carry both network and storage 
trafc at speeds of up to 10 Gbps. The 
X540-T2 adapter combines support for 
all of these trafc types in one adapter at 
no additional cost and with no additional 
licensing fees for the adapter.
Intel’s Unied Networking solutions 
are enabled through a combination of 
standard Intel® Ethernet products along 
with trusted network protocols integrated 
in the operating systems. Thus, Unied 
Networking is available on every Server 
either through LAN-on-Motherboard 
(LOM) implementation or via an add-in 
Network Interface Card (NIC).
Intel has delivered high quality Ethernet 
products for over 30 years and our 
Unied Networking solutions are built 
on the original principles that made us 
successful in Ethernet:
• Open Architecture integrates network-
ing with the server, enabling IT managers 
to reduce complexity and overhead while 
enabling a flexible and scalable data cen-
ter network. 
• Intelligent Offloads lower cost and 
power while delivering the application 
performance that customers expect. 
• Proven Ethernet Unified Networking 
is built on trusted Intel Ethernet technol-
ogy, enabling customers to deploy FCoE 
or iSCSI while maintaining the quality of 
their traditional Ethernet networks. 
iSCSI Simplifies SAN Connectivity
iSCSI uses Ethernet to carry storage traf-
c, extending the familiarity and simplicity 
of Ethernet to storage networking, with-
out the need for SAN-specic adapters or 
switches. Intel® Ethernet X540 is the easi-
est, most reliable, and most cost-effective 
way of connecting servers to iSCSI SANs.
Open FCoE Consolidates LANs and 
Legacy SANs
Intel’s Open FCoE solution enables Intel® 
Ethernet 10 Gigabit Server products 
(adapters and controllers) to support Fibre 
Channel payload encapsulated in Ethernet 
frames. There is no upgrade charge for 
Open FCoE on the adapter. Just as with 
iSCSI, now customers can easily connect 
to an FCoE network with Intel 10 GbE 
solutions. 
For the rst time, Open-FCoE is now 
supported on 10GBASE-T. As 10GBASE-T 
switches come to market enabled with 
FCoE support, the X540 is ready when 
you’re ready. This enables you to use 
cost-effective 10GBASE-T for all your 
converged networking needs. The Open-
FCoE architecture uses a combination 
of FCoE initiators in Microsoft Windows* 
and Linux* operating systems and in 
the VMware* ESXi hypervisor to deliver 
high-performance FCoE solutions using 
standard 10 GbE Ethernet adapters.
This approach enables IT managers to 
simplify the data center and standardize 
on a single adapter for LAN and SAN con-
nectivity. The Intel® Ethernet Converged 
Network Adapter X540-T2 is designed to 
fully ofoad the FCoE data path to deliver 
full-featured converged network adapter 
(CNA) functionality without compromising 
on power efciency and interoperability. 
Data Center Bridging (DCB) Delivers 
Lossless Ethernet
Conventional Ethernet does not guar-
antee successful data delivery, which is 
not acceptable for SAN trafc. Ethernet 
enhancements such as Data Center Bridg-
ing (DCB) overcome that limitation with 
technologies that guarantee lossless deliv-
ery, congestion notication, priority-based 
ow control, and priority groups.
The combination of 10 GbE and unied 
networking helps organizations overcome 
connectivity challenges and simplify the 
data center infrastructure. 10 GbE pro-
vides a simple, well-understood fabric for 
virtualized data centers, one that helps 
reduce cost and complexity as the number 
of virtual machines continues to grow.
