The QLogic 3400 Series of OEM-proven Intelligent Ethernet Adapters provides exceptional value in delivering industry-leading features and performance to enable the most efficient and agile software-defined data centers (SDDNs). Designed for server and network virtualization, the 3400 Series Adapter provides stateless offload support for VXLAN/NVGRE and SR-IOV to boost server CPU efficiency and maximize application performance.

The QLogic 3400 Series Intelligent Ethernet Adapters—available in 10GBASE-T (RJ45), SR optic, and direct attach copper (DAC)—support LAN (TCP/IP) traffic at 10Gbps Ethernet (GbE) line-rate speeds. The 3400 Series Adapter is the solution of choice for workload-intensive virtualized computing environments, providing a reliable, high-performance 10GbE connectivity solution.

  • PCI Express Gen3 x8
  • Delivers full line-rate 10GbE performance across both ports
  • Enables provisioning of 10GbE ports for greater deployment flexibility through switch-independent NIC partitioning (NPAR)
  • Boosts host CPU efficiency with hardware offloads for NVGRE and VXLAN tunnels
  • Improves reliability and interoperability—leverages QLogic’s market-proven Ethernet architecture and software
  • 10GBASE-T version provides a low-cost and easy-to-install RJ45 network connectivity solution that is backward compatible with existing 1GbE
  • Energy Efficient Ethernet (EEE) support reduce idle power consumption in RJ45-based networks
  • Network boot support for pre-execution environment (PXE) 2.0
  • PCI-SIG single root input/output virtualization (SR-IOV)
  • Data center bridging (DCB)
  • Low-profile PCIe form factor

The 3400 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 3400 Series Intelligent Ethernet 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 evolution of data centers—triggered by high-density server virtualization, software-defined networking (SDN), and multitenant cloud computing platforms—demands a high-performance 10GbE solution that boosts CPU efficiency, and reduces capital expenditures (CAPEX) and operating expense (OPEX) of the migration to 10GbE. The QLogic 3400 Series Intelligent Ethernet Adapters are the solution of choice for workload-intensive computing environments, providing a reliable, highperformance 10GbE connectivity solution.

Simplified Migration to 10GbE
QLogic 3400 Series Adapters feature a high-speed flexible architecture and switch-independent NIC partitioning (NPAR) technology. Designed for both physical and virtual environments, this switch-agnostic approach enables administrators to split up the 10GbE network pipe to divide and reallocate bandwidth and resources, as needed, at the adapter level.

  • Customers deploying rack and tower servers with multiple GbE adapters can greatly benefit from consolidating multiple network adapters and freeing up PCI slots for other add-in card upgrades.
  • With NPAR, 3400 Series Adapters can further partition their network bandwidth into multiple virtual connections, making one dual-port adapter appear as eight adapters to the OS for use by the applications.
  • NPAR greatly simplifies the physical connectivity to the server, reduces implementation time, and lowers the acquisition cost of the 10GbE migration.
  • Available in 10GBASE-T, SR optic, and direct attach copper (DAC), 3400 Series Adapters are the ideal choice for migrating multiple 1GbE network connections to consolidated 10GbE.

Designed for Next-Gen Server Virtualization
3400 Series Intelligent Ethernet Adapters support today's most compelling set of powerful networking virtualization features, including SR-IOV, enhanced network 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, switchindependent NIC partitions per adapter port. Dynamic and fine-grained bandwidth provisioning enables control of network traffic from VMs and hypervisor services.
  • Concurrent support for SR-IOV and NPAR enables virtual environments with the choice and flexibility to create an agile virtual server platform.
  • Availability of both RSS and TSS allows for more efficient load balancing across multiple CPU cores.

High-Performance Multitenancy Delivered
As large-scale private and public cloud deployment requirements for isolation and security stretch the boundaries of traditional VLANs, the 3400 Series Intelligent Ethernet Adapter delivers network virtualization features for high-performance overlay networks with tunneling offloads for VXLAN and NVGRE technologies.

  • Designed to meet the demands of large, public cloud deployments, the 3400 Series Adapters feature tunneling offloads for multitenancy with VXLAN and NVGRE support.
  • Line-rate 10GbE performance across individual ports, in multitenant deployments, maximizes server-processing performance by delivering an offloaded NIC for cloud deployments on Microsoft Windows Server 2012 and VMware vSphere™ 5.

Operating Expense Savings with Low-Power PCI Express Gen3
The 3400 Series 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 3400 Series Intelligent Ethernet Adapters to deliver linerate, dual-port performance without compromise.
  • 3400 Series Adapters are designed to provide maximum power efficiency, consuming a mere 7.1 watts (single-port SFP+) of power and yet delivering a high-performance, I/O connectivity platform.
