Dual-port 10 Gigabit
Ethernet Throughput
The HP Adapter delivers 20 Gbps full duplex Ethernet transfer rate per port (40 Gbps per
adapter), providing the network performance needed to improve response times and alleviate bottlenecks
that impact performance of next generation data centers. 10Gb Ethernet bandwidth is ideal for high
performance computing, database clusters, video on demand and more.
PCI Express Interface
The HP Adapter is designed with an eight lane (x8) PCI Express bus based on the PCIe v2.0
standard. The adapter is backward compatible with four lane (x4) PCI Express, automatically auto-sensing
between x8 and x4 slots.
Jumbo Frames
The HP Adapter supports jumbo frames (also known as extended frames), permitting up to a 9K
byte (KB) transmission unit (MTU) when running Ethernet I/O traffic. This is over 5X the size of a standard
1500-byte Ethernet frame. With jumbo frames, networks can achieve higher throughput performance and
greater CPU utilization. These attributes are particularly useful for database transfer and tape backup
operations.
TCP/IP Stateless
Offloading
TCP, IP, UDP checksum offload, Large Send Offload (LSO), TCP, Segmentation Offload (TSO). These
features optimize host efficiency, leaving the CPU available for other duties.
The HP Adapter powered by Intel® 82599 controller offers TCP/IP stateless intelligent offloading
capability.
MSI and MSI-X
Message Signaled Interrupt (Extended) provides performance benefits for multi-core servers by load
balancing interrupts between CPUs/cores. The HP Adapter supports MSI and MSI-X.
802.1Q VLANs
IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of the HP
adapter to be separated into multiple virtual NICs for added network segmentation and enhanced security
and performance. VLANs increase security by isolating traffic between users. Limiting the broadcast traffic
to within the same VLAN domain also improves performance. The HP Adapter provides support
for 802.1Q (VLAN).
