Intel® 10 Gigabit AT2 Server Adapter

10 gigabit BASE-T Ethernet server adapters designed for multi-core processors and optimized for virtualization

10 gigabit performance at the low cost of copper

This 10 gigabit AT2 Ethernet server adapter showcases Intel's second-generation standards-based 10BASE-T adapter in a low-profile PCI Express* form factor. It provides bandwidth intensive applications highly affordable 10 gigabit Ethernet (GbE) network performance with cost-effective RJ-45 connections for distances up to 100 meters. High-speed server connectivity - once reserved for costly, proprietary technologies such as high performance computing (HPC) clusters and grid-based computing - can now be achieved with the standardized connectivity of the Intel® 10 Gigabit AT2 Server Adapter. Intel's adapter also provides 1000BASE-T support for gigabit connections to legacy switches.

Product information

Features and benefits

Intel® 82598EB 10 Gigabit Ethernet Controller
  • 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*
Intel® QuickData Technology1
  • DMA Engine: Enhances data acceleration across the platform (network, chipset, processor), thereby lowering CPU utilization
  • Direct Cache Access (DCA): Allows the processor to pre-fetch the data from memory, thereby avoiding cache misses and improving service level agreements (SLA) of the applications
iSCSI remote boot support
  • Provides centralized storage area network (SAN) management at a lower cost than competing iSCSI solutions
MSI-X support
  • Minimizes the overhead of interrupts
  • Allows load balancing of interrupt handling between different cores/CPUs
Virtual Machine Device queues (VMDq)
  • Allows the efficient routing of packets to the correct target machine in a virtualized environment using multiple hardware queues
  • Ensures transmit fairness and prevents head-of-line blocking
Low latency
  • Ability to toggle between the interrupt aggregation and non-aggregation mode based on the type of data being transferred
Optimized queues: 32 transmit (Tx) and 64 receive(Rx) per port
  • Enhances network performance and reduces CPU utilization in the virtualized environment
  • Reduces I/O overhead on the hypervisor in a virtualized server by performing data sorting and coalescing in the network silicon
Network packet handling without waiting or buffer overflow
  • Efficient packet prioritization
Support for most network operating systems (NOS)
  • Enables widespread deployment
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
Remote management support
  • Reduces support costs with remote management based on industry-wide standards
RJ-45 connections over category-6A cabling
  • Ensures compatibility with cable lengths up to 100 meters
RoHS-compliant,2 lead-free3 technology
  • Compliant with the European Union directive (effective as of July 2006) to reduce the use of hazardous materials
Intel® PROSet Utility for Microsoft Windows* Device Manager
  • Provides point-and-click power over individual adapters, advanced adapter features, connection teaming, and Virtual Local Area Network (VLAN) configuration
Intel backing
  • Backed by an Intel limited lifetime warranty, 90-day money-back guarantee (U.S. and Canada), and worldwide support
