Dual- and Single-Port 10 Gigabit SFP+ Ethernet Converged Network Adapters Provide Ultimate
Flexibility and Scalability in Virtual and Unified Storage Environments
Overview
Intel’s family of adapters, the Intel®
Ethernet Converged Network Adapter
X520 with SFP+ connectivity, are the
most flexible and scalable Ethernet
adapters for today’s demanding data
center environments. Data center
networks are being pushed to their limits.
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 driving the need for
10 Gbps 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.
Powered by Intel’s third-generation 10
GbE network controller, the Intel® Ethernet
82599 10 Gigabit Ethernet Controller,
the X520 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.
Best Choice for Virtualization
The explosive growth in virtualization
is leading to an increasing demand for
network performance. With more Virtual
Machines (VMs) running on each multi-core
server, networking traffic is dramatically
increased, with each VM competing for
available I/O bandwidth. Intel’s family
of Intel Ethernet Converged Network
Adapter X520 addresses networking
bottlenecks in virtualized environments.
These adapters enable network-intensive
applications to achieve the performance
expected in a virtualized environment.
The Intel Ethernet X520 family of
adapters provides the best networking
performance available in the industry,
whether the physical port is configured
in an emulation mode using the virtual
switch in the Virtual Machine Monitor
(VMM), or is directly assigned to a
virtual machine. In the emulation mode,
Intel’s I/O technology, Virtual Machine
Device queues¹ (VMDq) optimizes
network performance by offloading data
sorting and copying from the software
Virtual Switch in the VMM to the Intel
Ethernet 82599 10 Gigabit Controller.
This configuration is best suited for a
large number of VMs running standard
applications that have limited bandwidth
and latency requirements.
For mission-critical applications, where
dedicated I/O is required for maximum
network performance, users can assign
a dedicated virtual adapter port to a VM.
Using the PCI-SIG SR-IOV capability on
an Intel Ethernet X520 adapter provides
direct VM connectivity and data protection
across VMs. 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 highest I/O throughput and lowest
latency performance such as database,
storage, financial and other applications.
