Overview

The integrated NC7781 LOM incorporates a variety of features on a single chip using Category 5 (or better) twisted-pair cabling, thus increasing flexibility and reducing support costs. The N7781 ships with industry-standard drivers that are compatible with other NC series gigabit adapters. This LOM supports 10/100/1000 Mbps Ethernet speeds as well as a PCI-X 64-bit/133MHz data path, compatible with existing PCI bus architectures. This range of features enables ProLiant server customers to protect their current hardware investment while also future-proofing their ProLiant servers for the inevitable increase in networking throughput. Additionally, the NC7781ships with support for Network Fault Tolerance, Load Balancing, Jumbo Frames, and various TCP offload capabilities that improve performance.

The integrated NC7781 is a PCI-X based LOM (LAN on Motherboard) embedded chip that provides high-performance and featurerich functionality on 10BASE-T, 100BASE-TX and 1000BASE-TX networks. Along with all the advanced features that ProLiant customers have come to expect, the NC7781 includes support for Jumbo Frames, Wake on LAN (WOL), Dual Address Cycles (DAC), and Pre-Boot Execution environment (PXE).

Performance

Gigabit Ethernet Throughput, High-Performance, and Flexibility for Today's Businesses

Gigabit Ethernet Throughput, High-Performance, and Flexibility for Today's BusinessesGigabit Ethernet Throughput, High-Performance, and Flexibility for Today's Businesses A 1000 Mbps Ethernet transfer rate delivers outstanding network performance that improves response time and removes bottlenecks

across the entire network. Full-duplex support allows the NC7781 to transmit and receive data simultaneously at rates up to 1000 Mbps for Gigabit Ethernet.

Port Bonding or Load Balancing

Port Bonding or Load BalancingPort Bonding or Load Balancing Transmit Load Balancing (TLB) and Switch-Assisted Load Balancing (FEC/GEC/802.3ad static-mode configuration only) are two

port-bonding methods supported by the NC7781. TLB provides both failover and balancing of transmit traffic across all adapters for increased performance. For even higher performance, Switch-Assisted Load Balancing (SLB) provides port failover and balancing of both transmit and receive traffic across all ports when connected to a switch that supports this feature. Both of these load balancing techniques build a bigger pipe for improved networking bandwidth and enable users to install up to 7 adapters in addition to this LOM (for a team consisting of 8 ports) within a ProLiant server to aggregate their throughput up to a maximum of 16 Gigabits per second full-duplex transmissions.

Bus-mastering

Bus-masteringBus-mastering This LOM uses bus-mastering technology to maximize throughput and minimize CPU utilization.

PCI-X Data Path

PCI-X Data PathPCI-X Data Path HP was an early champion of PCI-X bus technology and has played a key role in the development and industry adoption of the PCI-X

specification. The NC7781 is HP's first LOM to feature a 64-bit/133MHz data path, which yields faster transmissions with lower CPU utilization.

Jumbo Frames

Jumbo FramesJumbo Frames Jumbo Frames (also known as Extended Frames) offer a 9K byte Maximum Transmission Unit (MTU), which is six times the size of

traditional Ethernet frames. The NC7781 supports jumbo frames as a way to achieve higher throughput and better CPU utilization when deployed in a network infrastructure that supports them. Jumbo frames are particularly useful for database transfers and tape backups.

TCP Offloads and Interrupt Coalescing

TCP Offloads and Interrupt CoalescingTCP Offloads and Interrupt Coalescing The NC7781 supports TCP Checksum Offloads as well as TCO Segmentation Offloads. Both reduce the load on the CPU for an

overall improved system response. Interrupt Coalescence groups multiple packets and issues a single interrupt to the host. This process optimizes host efficiency, leaving the CPU available for other duties.

Security/Reliability

Network Fault Tolerance (NFT)

Network Fault Tolerance (NFT)Network Fault Tolerance (NFT) The Network Fault Tolerance feature of the NC7781 ensures that the server can always keep an active link. After installing a second,

compatible adapter, if the primary network connection fails, the second, backup adapter will automatically take over, retaining the network connection. The NC7781 can be configured to fail over to almost any NC-series adapter by using the latest drivers.

Network Management

Server Integration

Server IntegrationServer Integration HP's ProLiant SmartStart configuration utility includes setup support for the NC7781 so that the NIC can be configured as part of the

SmartStart configuration process. Insight Manager can recognize the NC7781 individually or in port bonded teams, and can collect and report SNMP statistics on the server adapter events. The Network Management System can also collect and report SNMP statistics. Additionally, Integrated Management Log (IML) support is provided by the NC7781 for critical event logging on ProLiant servers.

Wake On LAN

Wake On LANWake On LAN The NC7781 provides Wake on LAN (WOL) support in ProLiant servers that support WOL. A system that supports Wake on LAN can

remain available to a system administrator during its normal downtime. Once the machine is awakened, the system administrator can remotely control, audit, debug, or manage the machine.

Auto-negotiation

Auto-negotiationAuto-negotiation The NC7781 automatically senses and configures itself to 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 at the other end of the cable.

Management Support
