PXE, jumbo frames, checksum and segmentation offload, IPv6 and RSS

IEEE 1588 (Time synchronization)

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 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

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

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 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

Support for PXE enables automatic deployment of computing resources remotely from anywhere. It allows anew 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

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 (SR-IOV) provides a mechanism to bypass the host system hyper visor 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

For overall improved system response, this adapter supports standard TCP/IP offloading techniques including: 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

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

Windows Hyper-V VMQ (VMQ) is a feature available on servers running Windows Server 2008 R2 with VMQ enabled Ethernet adapters

VMQ uses hardware packet filtering to deliver packet data from an external Virtual machine network directly to virtual machines, which reduces the overhead of routing packets and copying them from the management operating system to the virtual machine
