Data Sheet
OVERVIEW  
The QLogic
®
 8400 Series Converged Network Adapters support 
simultaneous LAN (TCP/IP) and SAN (Fibre Channel over Ethernet 
[FCoE] and iSCSI) traffic at 10Gbps Ethernet (GbE) line rate speeds. The 
8400 Series provides extremely low host CPU usage by enabling full 
hardware offloads.
The 8400 Series leverages QLogic’s long-standing industry leadership in 
Ethernet by providing the highest levels of performance, efficiency, and 
scalability for the enterprise data center.
For more effective utilization of the 10GbE bandwidth, the QLogic 
8400 Series Converged Network Adapters offer switch-independent NIC 
partitioning (network partitioning [NPAR]), which enables segmentation of a 
single 10GbE port into multiple network partitions and dynamic allocation 
of bandwidth to each port. The segmentation allows IT organizations to 
optimize resource utilization while lowering infrastructure and operational 
costs.
The acceleration of data center convergence—triggered by virtualization, 
software-defined networking (SDN), and multitenant cloud computing 
platforms—demands high-performance, converged network solutions. 
The QLogic 8400 Series Converged Network Adapters are the solution 
of choice for workload-intensive computing environments, providing a 
reliable, high-performance 10GbE connectivity solution.
