Overview: The ProLiant NC6770 PCI-X Gigabit Server Adapter is HP's first fiber-optic networking solution to combine Gigabit Ethernet speed with PCI-X bus technology. The NC6770 is a single port Gigabit adapter that supports 1000Mbps speed. Along with other the advanced features that ProLiant customers have come to expect the NC6770 includes support for network failover and load balancing PCI hot plug capability Jumbo Frames Dual Address Cycles (DAC) large send offload capability and Pre-boot Execution Environment (PXE). The NC6770 PCI-X Gigabit Server Adapter solves customer problems by bringing near-wire speed performance to fiber-optic cabling plants thereby allowing customers to protect their investment in a fiber-optic infrastructure. Furthermore the increased capability of the NC6770's PCI-X data path helps to remove network bottlenecks in even the most congested networks. The NC6770 PCI-X Gigabit Server Adapter allows ProLiant customers to easily move from twisted-pair to fiber-optic cabling. This decision is typically motivated by the need to support greater distances the desire for greater security or for EMI protection in noisy environments e. g. manufacturing plants. Some customers want to future-proof their environment by deploying fiber-optic cabling to support Ethernet Gigabit speeds rather than use copper wiring for their Ethernet Gigabit requirements.
