Throughput­Theoretical Bandwidth

802.1Q VLANs

Checksum & Segmentation Offload

Converged Network Utility (CNU)

Configuration Utilities

This adapter delivers 50 Gb/s bi-directional Ethernet transfer rate per port (200 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.

Normally the TCP Checksum is computed by the protocol stack. Segmentation Offload is technique for
increasing outbound throughput of high-bandwidth network connections by reducing CPU overhead. The
technique is also called TCP segmentation offload (TSO) when applied to TCP, or generic segmentation offload
(GSO).

This adapter supports Converged Network Utility (CNU) a manageability application to configure converged
network adapters (CNAs) and Ethernet adapters on HPE servers. This host based utility supports for both
GUI and Command Line Interface (scriptable), and can be used to configure Ethernet, FCoE, iSCSI and NPAR
related features/functionality on multiple OS platforms including Windows and Linux. CNU is able to configure
multiple HPE adapters from various network controllers at the same time. Users can benefit easier setup steps,
shorter re-boot time, and one-stop solution for multiple adapters via CNU.

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

Standard Features

operating systems. Additionally, support for scripted installations of teams in a Microsoft Windows environment
allow for unattended OS installations.

DPDK

HPE Sea Of Sensors 3D

IPv6

Jumbo Frames

LED Indicators

Management Support

This adapter supports DPDK with benefit for packet processing acceleration and use in NFV deployments.

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.

IPv6 uses 128-bit addressing allowing for more devices and users on the internet. IPv4 supported 32-bit
addressing.

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) (MSI-X)

Network Adapter Teaming

Optimized for Virtualization

Preboot eXecution Environment (PXE)

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.

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.

Standard Features

RoCE v2

Receive Side Scaling (RSS)

Server Integration

This adapter supports RoCE v1 and v2. RoCE v2, also sometimes called "Routable RoCE" which adds
Concurrent RoCE v1 and v2 support, SR-IOV support, QoS with hierarchical TX scheduling, ECN-based
congestion control for RoCE v2. RoCE is an accelerated I/O delivery mechanism that allows data to be
transferred directly from the user memory of the source server to the user memory of the destination
server bypassing the operating system (OS) kernel. Because the RDMA data transfer is performed by the
DMA engine on the adapter's network processor, the CPU is not used for the data movement, freeing it to
perform other tasks such as hosting more virtual workloads (increased VM density). RDMA also bypasses
the host's TCP/IP stack, in favor of upper layer InfiniBand protocols implemented in the adapter's network
processor. The bypass of the TCP/IP stack and the removal of a data copy step reduce overall latency to
deliver accelerated performance for applications such as Microsoft Hyper-V Live Migration, Microsoft SQL and
Microsoft SharePoint with SMB Direct.

RSS resolves the single-processor bottleneck by allowing the receive side network load from a network adapter
to be shared across multiple processors. RSS enables packet receive-processing to scale with the number of
available processors.

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.

Single-Root I/O Virtualization

Precision Time Protocol (IEEE 1588 PTP)

Tunnel Offload

VMware NewQueue and Microsoft Virtual Machine Queue (VMQ)

Single-Root I/O Virtualization (SR-IOV) provides a mechanism to bypass the host system hypervisor in virtual
environments providing near metal performance and server efficiency. SR-IOV provides mechanism to create
multiple Virtual Functions (VFs) to share single PCIe resources. The device is capable of SR-IOV, and requires
Server BIOS support, controller firmware, and OS support.

Synchronization of system clocks throughout a network, achieving clock accuracy in the sub-microsecond
range, making it suitable for measurement and control systems.

Minimize the impact of overlay networking on host performance with tunnel offload support for VXLAN
and NVGRE. By offloading packet processing to adapters, customers can use overlay networking to increase
VM migration flexibility and virtualized overlay networks with minimal impact to performance. HPE Tunnel
Offloading increases I/O throughput, reduces CPU utilization, and lowers power consumption. Tunnel Offload
supports VMware's VXLAN and Microsoft's NVGRE solutions.

VMware NetQueue is technology that significantly improves performance of 10 Gigabit Ethernet network
adapters in virtualized environments.
