X520-T2 Datasheet, PDF (2/4 Pages) Intel Corporation – 10 Gigabit BASE-T Ethernet Server Adapter Designed for Multi-Core Processors and Optimized for Virtualization

Virtualization (SR-IOV). VMDq improves data processing by offload-
ing the sorting and queuing functionality to the I/O controller from
the VMM. SR-IOV provides direct connectivity to the VMs to deliver
near-native performance and VM scalability. VMDc also provides
flexibility with mobility by enabling VM migration between physical
servers.
Unified Networking
The fast growth in storage capacity coupled with server
virtualization has brought the need for Storage Area Network
(SAN) to the forefront. To satisfy this growing demand, the Intel
Ethernet Server Adapter X520-T2 supports iSCSI acceleration
and provides advanced features for unified networking. Fast and
reliable networked storage can be achieved via native iSCSI sup-
port with Microsoft, Linux,* and VMware operating systems as
well as support for iSCSI remote boot. Intel’s unified networking
solutions enable cost-effective connectivity to the SAN; custom-
ers can use NAS or iSCSI to carry storage traffic over Ethernet.

• Industry-leading, energy-efficient design for next-generation 10 Gigabit performance
and multi-core processors
Low-profile
• Enables higher bandwidth and throughput from standard and low-profile PCIe slots and servers
Load balancing on multiple CPUs
• Increases performance on multi-processor systems by efficiently balancing network loads across
CPU cores when used with Receive-Side Scaling from Microsoft* or Scalable I/O on Linux*
iSCSI remote boot support
• Provides centralized Storage Area Network (SAN) management at a lower cost than competing
iSCSI solutions
Support for most Network Operating Systems (NOS)
• Enables widespread deployment
RoHS compliant,₂ lead-free₃ technology
• Compliant with the European Union directive (effective as of July 2006) to reduce the use of hazard-
ous materials
Intel® ProSet Utility for Windows* Device Manager
• Provides point-and-click management of individual adapters, advanced adapter features, connection
teaming, and virtual local area network (VLAN) configuration
Compatible with x8 and x16 standard and low-profile PCI
Express* slots
• Allows each PCI Express* slot port to operate without interfering with the other
I/O Features for Multi-core Processor Servers
MSI-X support
• Minimizes the overhead of interrupts
• Allows load balancing of interrupt handling between different cores/CPUs
Low latency
• Based on the sensitivity of the incoming data, the adpater can bypass the automatic moderation of
time intervals between the interrupts
Header Splits and Replication in Receive
• Helps the driver focus on the relevant part of the packet without the need to parse it 
Multiple Queues: 16 queues per port
• Network packet handling without waiting or buffer overflow providing efficient packet prioritization
Tx/Rx IP, SCTP, TCP, and UDP checksum offloading (IPv4,
IPv6) capabilities
• Lower processor usage
• Checksum and segmentation capability extended to new standard packet type
Tx TCP segmentation offload (IPv4, IPv6)
• Increased throughput and lower processor usage
• Compatible with large-send offload feature (in Microsoft Windows* Server operating systems)
IPsec Offload
• Offloads IPsec capability onto the adapter instead of the software to significantly improve through-
put and CPU usage (for Windows* 7, Windows* 2008 Server R2, Windows* 2008 Server, and Vista*)
MacSec
• IEEE spec: 802.1ae
• Layer 2 data protection with encryption/authentication ability between devices (e.g, routers,
switches)
• MacSec is designed into the network adapter hardware. These adapters are prepared to provide
MacSec functionality when the ecosystem is ready to support this new technology
Compatible with x8 and x16 standard and
low-profile PCI Express* slots
• Allows each PCI Express* slot port to operate without interfering with the other
Receive and Transmit Side Scaling for Windows environment • Enables the direction of the interrupts to the processor cores in order to improve the CPU utilization
and Scalable I/O for Linux* environments (IPv4, IPv6, TCP/
rate
UDP)
