Fibre Channel over Ethernet (FCoE)
for the Windows*-based Intel®Ethernet Server Adapter X520 Series
10 Gigabit Ethernet (10 GbE), is quickly being adopted as the datacenter deployment and upgrade standard, enabling applications to
scale and perform at a higher level than ever before. In conjunction
with new processor advancements, applications and operating
systems can see virtually line rate on the 10 GbE adapters provided by Intel today.
Bridging (DCB) technology. DCB enables the switch to notify
the adapter that there is congestion on the port and to pause
individual traffic streams until it subsides.
Intel, as a long-time leader in the Datacenter Ethernet market,
is now adopting the new Fibre Channel over Ethernet (FCoE)
Standard (T11-FC-BB-5). Since the beginning of FCoE, Intel
has worked hand-in-hand with other industry leaders and this
work has helped in setting the standard for Fibre Channel over
Ethernet today.
Upgrading to FCoE is as simple as acquiring a Fibre Channel Forwarding-enabled switch (such as, Cisco* Nexus* 5000 or Brocade*
8000), and a 10 GbE adapter that supports FCoE protocol. The
Fibre Channel Forwarder (FCF) then connects to your traditional
SAN and LAN infrastructures by an Inter-Switch Link (ISL) to the
SAN (E-Port), and by trunk ports to the LAN (Spanning-Tree).
Feature Introduction
With its latest software releases, Intel is launching FCoE support
for Microsoft* Windows* over X520 Family adapters. When
developing these adapters, Intel architects designed them to
support several offload features specifically for FCoE, including:
•
Transmit and Receive (Tx – Rx) FC CRC Processing
•
Receive Direct Data Placement (DDP)
•
Receive Exchange-Id Packet Filtering
•
Large Sequence Offload
These adapters also offload the main FCoE data paths to
improve throughput. The result is comparable FCoE performance
for realworld workloads compared to that of CNAs. While the
supported offload assists do not completely offload the FCoE
protocol, Intel has offloaded the most common and frequently
used commands.
With FCoE also comes the lossless Ethernet of Data Center
Product Walk-Through
Intel has integrated the management of FCoE and the Virtual
®
Storage Controllers into the Intel PROSet for Windows Device
Manager. There is no required application to install or manage.
FCoE features give you the look and feel typical of industrystandard Fibre Channel.
Additional features include:
•
•

•
Multi-Fabric Enabled Ports
Queue Depth Management
Link Down Timeout Settings
Manual DCB Settings Option
FCoE Boot Options
