Features

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/OAT

2

•  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-compliant

3

•  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 

Conserve valuable PCI Express (PCIe*) server slots while adding 
10 Gigabit Ethernet capability with the Intel 10 Gigabit CX4 Dual 
Port Server Adapter. The dedicated input/output (I/O) bandwidth 
of PCIe ensures priority performance on each port — without 
bus sharing — for 10 Gigabit Ethernet connectivity, as well as a 
low-profile design, which improves server throughput and rack 
density at the same time. In addition, eight-lane PCIe enables 
maximum bandwidth for fast and efficient data transfer.

Advances for Unified Storage

The fast growth in storage capacity coupled with server virtual-
ization has brought the need for Storage Area Network (SAN) to 
the forefront. To satisfy this growing demand, Intel’s 10 Gigabit 
CX4 Dual Port Server adapters support iSCSI acceleration through 

Intel I/OAT and provide advanced features for unified storage con-
nectivity. Fast and reliable networked storage can be achieved via 
native iSCSI support with Microsoft, Linux*, and VMware operating 
systems as well as support for iSCSI remote boot.
