Dual-port 10 Gigabit Ethernet throughput:
  • 20,000 Mb/s full duplex Ethernet transfer rate per port (40 Gb/s aggregate full duplex)

PCI express interface:
  • Eight lane (x8) PCI Express bus based on the PCIe v2.0 standard.

  • Backward compatible with four lane (x4) PCI Express.

  • Automatically auto-sensing between x8 and x4 slots.

Jumbo frames:
  • 9,000 byte transmission unit (MTU)

  • Supports 9KB jumbo frames

  • Supports industry standard SR-IOV (Single Root Input Output Virtualization)

TCP stateless offloading:
  • TCP/IP checksum offload (TCO)

  • Large Send Offload (LSO) or TCP Segmentation Offload (TSO)

Interrupt coalescing:
  • Groups multiple packets, thereby reducing the number of interrupts sent to the host.

802.1p QoS tagging:
  • Allows to mark or tag frames with a priority level across a QoS-aware network for improved traffic flow.

Network management
Management support:
  • HP Systems Insight Manager or other management application that support SNMP.

Server integration:
  • Optimized for HP ProLiant servers.

  • Provides users with a single point of contact for both their servers and their network adapters.

LED indicators:
  • Bracket LED indicators show link integrity and network activity for easy troubleshooting.
  • Support for pre-boot execution environment (PXE) enables automatic deployment of computing resources remotely from anywhere. It allows a new or existing server to boot over the network and download software, including the operating system, from a management/ deployment server at another location on the network. Additionally, PXE enables decentralized software distribution and remote troubleshooting and repairs.
