Intel® 10 Gigabit CX4 Dual Port Server Adapter

10 Gigabit performance at the lowest cost per port

Adding to a robust family of 10 Gigabit Ethernet adapters, Intel is now offering the Intel® 10 Gigabit CX4 Dual Port Server Adapter. Following the 802.ak specification, the Intel 10 Gigabit CX4 Dual Port Server Adapter offers the lowest cost per port of all the current 10GbE interconnects. The low-profile PCI Express* form factor combined with two CX4 ports and a low-power envelope for energy efficiency, makes the board ideal for slot-constrained environments. 10GBASE-CX4 adapters are well-suited for customers with shorter distance and low latency requirements.

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® I/OAT2
  • Accelerates I/O with higher throughput and lower CPU utilization by offloading processing overhead
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 multiple 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
  • Network packet handling without waiting or buffer overflow
  • Efficient packet prioritization
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
Support for most Network Operating Systems (NOS)
  • Enables widespread deployment
  • Supports up to 100m with Intel® Connects Cable
CX4 connections over 8 pair, 100 Ohm, Twinaxial cabling
  • Ensures compatibility with cable lengths up to 15m
  • Supports up to 100m with Intel® Connects Cable
RoHS-compliant1
  • Compliant with the European Union directive 2002/95/EC 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
