The QLogic 8400 Series of OEM-proven Converged Network 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 the most demanding server and network virtualized environments, the 8400 Series Adapter provides full hardware offload support for iSCSI and FCoE protocols as well as VXLAN/NVGRE and SR-IOV to boost server CPU efficiency and maximize application performance.

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 Adapter provides extremely low host CPU usage by enabling full hardware offloads.

  • PCI Express Gen3 x8
  • Delivers full line-rate 10GbE performance across both ports
  • Industry-leading storage (FCoE and iSCSI) transactional performance
  • 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
  • Network boot support:
    • iSCSI remote boot
    • FCoE boot from SAN
    • 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 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.

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, 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.
  • 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.
