Multi-Port Server Adapters
Dual- and quad-port Gigabit Ethernet server adapters designed
for multi-core processors and optimized for virtualization
• High-performing, 10/100/1000
Ethernet connection
• Reliable and proven Gigabit Ethernet
technology from Intel Corporation
• Scalable PCI Express* interface provides
dedicated I/O bandwidth for I/O-intensive
networking applications
• Optimized for virtualized environments
• Flexibility with iSCSI Boot and choice of dualand quad-port adapters in both fiber and copper
The Intel® Gigabit ET, ET2, and EF Multi-Port Server Adapters are
Intel’s third generation of PCIe GbE network adapters. Built with
the Intel® 82576 Gigabit Ethernet Controller, these new adapters
showcase the next evolution in GbE networking features for
the enterprise network and data center. These features include
support for multi-core processors and optimization for server
virtualization.
Designed for Multi-Core Processors
These dual- and quad-port adapters provide high-performing,
multi-port Gigabit connectivity in a multi-core platform as well
as in a virtualized environment. In a multi-core platform, the
adapters support different technologies such
as multiple queues, receive-side scaling, MSI-X, and Low
Latency Interrupts, that help in accelerating the data across
the platform, thereby improving application response times.
The I/O technologies on a multi-core platform make use of the
multiple queues and multiple interrupt vectors available on the
network controller. These queues and interrupt vectors help in
load balancing the data and interrupts amongst themselves in
order to lower the load on the processors and improve overall
system performance. For example, depending upon the latency
sensitivity of the data, the low level latency interrupts feature
can bypass the time interval for specific TCP ports or for flagged
packets to give certain types of data streams the least amount
of latency to the application.
Optimized for Virtualization
This generation of PCIe Intel® Gigabit adapters provides improved

networking devices to the chipset and processors, which help
Use of multi-port adapters in a virtualized environment is very
important because of the need to provide redundancy and
data connectivity for the applications/workloads in the virtual
machines. Due to slot limitations and the need for redundancy
and data connectivity, it is recommended that a virtualized
physical server needs at least six GbE ports to satisfy the
I/O requirement demands.
Virtual Machine Device queues (VMDq)
VMDq reduces I/O overhead created by the hypervisor in a
virtualized server by performing data sorting and coalescing in
the network silicon.2 VMDq technology makes use of multiple
queues in the network controller. As data packets enter the
network adapter, they are sorted, and packets traveling to the
same destination (or virtual machine) get grouped together in a
single queue. The packets are then sent to the hypervisor, which
directs them to their respective virtual machines. Relieving the
hypervisor of packet filtering and sorting improves overall CPU
usage and throughput levels.
to improve system performance and application response times.
The different features include multiple queues and receive-side
scaling, Direct Cache Access (DCA), MSI-X, Low-Latency Interrupts, Receive Side Scaling (RSS), and others. Using multiple
queues and receive-side scaling, a DMA engine moves data using
the chipset instead of the CPU. DCA enables the adapter to
pre-fetch data from the memory cache, thereby avoiding cache
misses and improving application response times. MSI-X helps
in load-balancing I/O interrupts across multiple processor cores,
and Low Latency Interrupts can provide certain data streams a
non-modulated path directly to the application. RSS directs the
interrupts to a specific processor core based on the application’s
address.
Single-Root I/O Virtualization (SR-IOV)
For mission-critical applications, where dedicated I/O is required
for maximum network performance, users can assign a dedicated
virtual function port to a VM. The controller provides direct
VM connectivity and data protection across VMs using SR-IOV.
SR-IOV technology enables the data to bypass the software
virtual switch and provides near-native performance. It assigns
either physical or virtual I/O ports to individual VMs directly.

This technology is best suited for applications that demand the
network adapter hardware. These adapters are future-proof and
highest I/O throughput and lowest-latency performance such as
database, storage, and financial applications.
prepared to provide LinkSec functionality when the ecosystem
The PCI-SIG SR-IOV capability is a mechanism for devices to
advertise their ability to be directly assigned to multiple virtual
machines. This technology enables the partitioning of a PCI function into many virtual interfaces for the purpose of sharing the
resources of a PCI Express* (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/Orelated functions within the PCI Express hierarchy. Use of SR-IOV
with a networking device, for example, allows the bandwidth
of a single port (function) to be partitioned into smaller slices
that may be allocated to specific VMs, or guests, via a standard
interface.

of a network communication session. The IPsec offload feature
is designed to offload authentication and encryption of some
types of IPsec traffic and still delivers near line-rate throughput
and reduced CPU utilization.
LinkSec is an IEEE industry-standard feature that provides data
protection in the network. The IEEE 802.3ae and IEEE 802.3af
protocols provide hop-to-hop data protection between two
network devices in the transaction line between the host and
destination. The two network devices must support the LinkSec
technology. The network devices could be servers, switches, and

routers.
The Intel® Gigabit ET, ET2, and EF Multi-Port Server Adapters are
Intel’s first PCIe adapters to provide authentication and encryption for IPsec and LinkSec. LinkSec is already designed into the
