BENEFITS
Designed for Next-Gen Server Virtualization
The 8400 Series Converged Network Adapters support today’s most 
compelling set of powerful networking virtualization features: SR-IOV, 
switch-independent NIC partitioning (NPAR), tunneling offloads (VXLAN and 
NVGRE), and industry-leading performance, thus enhancing the underlying 
server virtualization features.
SR-IOV delivers higher performance and lower CPU utilization with 
increased virtual machine (VM) scalability.
QLogic NPAR enables up to four physical, switch-agnostic NIC partitions 
per adapter port that are switch independent. Dynamic and fine-
grained bandwidth provisioning enables seamless migration to 10GbE 
infrastructure.
Concurrent support for SR-IOV and NPAR enables virtual environments 
with the choice and flexibility to create an agile virtual server platform.
Designed to meet the demands of large public cloud deployments, the 
8400 Series Converged Network Adapters feature tunneling offloads for 
multitenancy with VXLAN and NVGRE support. 
The 8400 Series is designed for maximum flexibility, which enables 
simultaneous, fully-offloaded, high-performance, multiprotocol (FCoE, 
iSCSI, and NIC) support from each independent port of the adapter.
Extreme Application Performance
The QLogic 8400 Series Adapter features a high-speed, flexible 
architecture driven by independent ultra-high performance engines. It 
delivers the industry’s highest performance to meet and exceed the peak 
demands of the most demanding enterprise application or virtual platform.
Availability of both RSS and TSS allows for more efficient load balancing 
across multiple CPU cores.
Increases server performance with full hardware offload for storage 
traffic.
Industry-leading FCoE performance of up to 2.6 million IOPS, suitable 
for high-density server virtualization and large databases.
Industry-leading iSCSI performance of up to 1.5 million IOPS, suitable 
for a diverse set of applications leveraging the flexibility of iSCSI.
Operating Expense Savings with Low-Power PCI Express Gen3
The 8400 Series Converged Network Adapters are PCIe Gen3-based 
adapters that have one of the lowest power consumption profiles in the 
industry. 
Supporting the latest generation of host bus connectivity, PCIe Gen3 
enables the 8400 Series Adapters to deliver line rate dual-port 
performance without compromise.
The 8400 Series Adapters are designed to provide maximum power 
efficiency, consuming a mere 7.1 watts (single-port) of power and yet 
delivering a fully-offloaded, high-performance I/O connectivity platform.
Leadership, Confidence, and Trust
QLogic adapters offer users peace of mind and confidence, as proven 
through the company’s market share leadership: #1 in Converged Network 
Adapters. The 8400 Series Converged Network Adapters offer the highest 
reliability, availability, and serviceability options that customers rely on to 
meet and exceed stringent service-level agreements for enterprise data 
centers.
