Compaq NC7770 PCI-X Gigabit Server Adapter
244948-B21
The Compaq NC7770 PCI-X Gigabit Server Adapter is the first in a new generation of networking solutions to combine Gigabit Ethernet speed with PCI-X
bus technology. The NC7770 is a single port copper Gigabit server adapter that runs over Category 5 (or better) twisted-pair cabling. Along with all the
advanced features that ProLiant customers have come to expect, the NC7770 includes support for Jumbo Frames, Wake on LAN (WOL), Dual Address
Cycles (DAC), and Pre-Boot Execution environment (PXE).

Overview
The NC7770 supports 10/100/1000Mbps Ethernet speeds as well as a PCI-X 64-bit/133MHz data path, backwards compatible with existing PCI bus
architectures. This range of features enables Compaq customers to protect their current hardware investment while also future-proofing their ProLiant
servers for the inevitable increase in networking throughput. Additionally, the NC7770 ships with support for PCI Hot Plug, Network Fault Tolerance, Load
Balancing, Jumbo Frames, and various offload capabilities that improve performance. These improvements in speed and throughput come at a cost-
effective price for environments using Category 5 (or better) twisted-pair cabling.
P
ERFORMANCE
Gigabit Ethernet Throughput
Up to 1000Mbps Ethernet transfer rate delivers outstanding network performance that improves response time and removes bottlenecks across the entire
network.
PCI-X Data Path
Compaq 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 NC7770 is Compaq’s first server adapter to feature a PCI-X 64-bit/133MHz data path, which yields faster transmissions with lower CPU utilization.
Load Balancing
Transmit Load Balancing (TLB) and Switch-Assisted Load Balancing (SLB) are two advanced features used to build a bigger pipe for improved networking
bandwidth. These port bonding techniques enable users to install up to eight NC7770 adapters in a ProLiant server and aggregate their throughput up to
a maximum of 16Gigabits per second full-duplex transmissions.
