3D
This adapter delivers 2 Gb/s bi-directional Ethernet transfer rate per port (8 Gb/s per adapter), providing the
network performance needed to improve response times and alleviate bottlenecks.
IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of this 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.
This adapter automatically senses the speed of the device to which it is attached. It also automatically
configures for half or full duplex, depending on the duplex mode of the switch, hub, or router connected to
the adapter.
This adapter ships with a suite of operating system-tailored configuration utilities that allow the user to enable
initial diagnostics and configure adapter teaming. This includes a patented teaming GUI for Microsoft Windows
operating systems. Additionally, support for scripted installations of teams in a Microsoft Windows environment
allow for unattended OS installations.
Compliant with IEEE 802.3az, featuring advanced power savings features throttles power usage with network
load activity.
Support for the HPE Sea of Sensors which is a collection of 32 sensors that automatically track thermal activity heat - across the server. When temperatures get too high, sensors can initiate fans and make other adjustments
to reduce energy usage. A significant improvement lies in the ability to apply fan speed increases only to the
portion of the system that is rising in temperature, rather than all six fans in unison, which reduces the amount
of energy used for cooling.

Optimized for
Virtualization
This adapter supports Jumbo Frames (also known as extended frames), permitting up to a 9,000 byte (KB)
transmission unit (MTU) when running Ethernet I/O traffic. This is over five times the size of a standard 1500byte 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.
LED indicators show link integrity and network activity for easy troubleshooting.
This adapter ships with agents that can be managed from HPE Systems Insight Manager or other management
application that support SNMP.
Message Signaled Interrupt (Extended) provides performance benefits for multi-core servers by load balancing
interrupts between CPUs/cores.
This adapter support for NIC teaming helps IT administrators increase network fault tolerance and increased
network bandwidth, the team of adapters can work together as a single virtual adapter, providing support for
several different types of teaming enabling IT administrators to optimize availability, improve performance
and help reduce costs.
I/O Virtualization support for VMware NetQueue and Microsoft VMQ helps meet the performance demands
of consolidated virtual workloads.
PCI Express Interface
Preboot eXecution
Environment (PXE)
Server Integration
TCP/UDP/IP
The x4 PCI Express interface on this adapter is compatible with x4, x8, and x16 PCI slots. If installed in a x8
or x16 slot, the adapter will operate at the x4 speed.
Support for 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.
This adapter is a validated, tested, and qualified solution that is optimized for HPE ProLiant servers. Hewlett
Packard Enterprise validates a wide variety of major operating systems drivers with the full suite of web-based
enterprise management utilities including HPE Intelligent Provisioning and HPE Systems Insight Manager that
simplify network management.
This approach provides a more robust and reliable networking solution than offerings from other vendors and
provides users with a single point of contact for both their servers and their network adapters.
For overall improved system response, this adapter supports standard TCP/IP offloading techniques including:

Standard Features
TCP/IP, UDP checksum offload (TCO) moves the TCP and IP checksum offloading from the CPU to the network
adapter. Large send offload (LSO) or TCP segmentation offload (TSO) allows the TCP segmentation to be
handled by the adapter rather than the CPU.
Precision Time
Protocol (IEEE 1588
PTP)
Warranty
Synchronization of system clocks throughout a network, achieving clock accuracy in the sub-microsecond
range, making it suitable for measurement and control systems.
Maximum: The remaining warranty of the HPE product in which it is installed (to a maximum three-year, limited
warranty).
Minimum: One year limited warranty.
