Product Details

NC6770 PCI-X Gigabit Server Adapter, 1000 SX - *The HP NC6770 PCI-X Gigabit Server Adapter is the latest fiber-opticnetworking solution for ProLiant servers. The NC6770 is a single portfiber Gigabit server adapter that runs over multimode fiber cable. It isthe first server adapter to combine Gigabit Ethernet speed with PCI-X bustechnology for fiber-optic environments. *
Specifications Standard Models ---------------------------------------------------------------------------- Feature Attribute Gigabit A 1000Mbps Ethernet transfer rate delivers outstanding Ethernet network performance that improves response time and removes Throughput bottlenecks. PCI-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 NC6770 is our first fiber-optic server adapter to feature a PCI-X 64-bit/133MHz data path, which yields faster transmissions with lower CPU utilization than earlier PCI-based, gigabit fiber solutions. Load Balancing Transmit Load Balancing (TLB) and Switch-assisted Load Balancing (SLB) are two advanced features that customers can use to build a bigger pipe for improved networking bandwidth. These port bonding techniques enable users to install up to eight NC6770 adapters in a ProLiant server and aggregate their throughput up to a theoretical maximum of 16Gigabits per second full-duplex transmissions. Jumbo 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. Like all HP ProLiant server adapters, the NC6770 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. Advanced TCP TCP/IP is the protocol used in Ethernet transmissions; and Offloading typically the network's TCP/IP segmentation and transmission Capability are done by the operating system's protocol stack. The advanced capabilities of the NC6770 shown below improve network performance by offloading functions from the CPU to the adapter and are the most advanced TCP Offloading capabilities for ProLiant servers at the present time. TCP Checksum Offloads is a feature that reduces the load on the CPU for overall improved system response. TCP Segmentation Offloads and Large Send Offloads are capabilities that allow the TCP/IP segmentation to be handled by the adapter itself; thus saving host CPU cycles for enhanced performance when there are large amounts of data sent across the network. This capability further reduces the load on the CPU for overall improved system response. Interrupt Coalescence is a feature that groups multiple packets and issues a single interrupt to the host. This process optimizes host efficiency, leaving the CPU available for other duties. PCI-X Support PCI-X technology ensures hardware investment protection by for Traditional retaining backward compatibility with the standard PCI bus PCI slots architecture at the device and driver level. When the NC6770 is used in a 64/100, 64/66, 64/33, or 32/33 IO slot, its performance is limited to the maximum of the conventional bus architecture. Network Fault Network Fault Tolerance, sometimes called "failover" or "NIC Tolerance (NFT) Redundancy," allows for the installation of multiple NC6770 server adapters so that the active device can be backed up by a redundant adapter to improve availability. HP's teaming utility also allows users to specify that when a failed adapter is fixed and replaced, the original adapter resumes its function as the primary network connection. PCI Hot Plug The NC6770 ships with PCI Hot Plug support, which enables it to be replaced or added to a PCI Hot Plug compatible server without powering down the system. This feature provides increased system availability and serviceability in business-critical computing environments. EMI and Because the NC6770 runs over fiber-optic cabling, users are Security assured of the highest protection against EMI interference Protection from machinery or lighting. The high security provided by fiber cabling reduces the threat of unauthorized access to data running over the network. Distance The NC6770 supports cable runs up to 550 meters on 50?m capabilities multimode fiber cable. This is ideal for environments where the limitations of twisted-pair wiring do not allow for sufficient distances between devices. Management Like all ProLiant server adapters, the NC6770 ships with Support drivers and agents that can be managed from all versions of Insight Manager Additionally, it supports any management applications that supports SNMP. Server The SmartStart? configuration utility includes setup support Integration for the NC6770 so the adapter can be configured as part of the SmartStart configuration process. Insight Manager can recognize the NC6770 individually or in port-bonded teams, and can collect and report SNMP statistics on the adapter events. Integrated Management Log (IML) support is provided by the NC6770 for critical event logging on ProLiant servers. Configuration Each NC6770 ships with a suite of OS-tailored configuration Utilities utilities that allow the user to run initial diagnostics and configure adapter teams for Network Fault Tolerance, Transmit Load Balancing, or Switch-assisted Load Balancing (802.3ad static-mode configuration only) in the Windows? 2000 and Windows NT? operating systems. LED Indicators Bracket LED indicators show link integrity, network activity, and network speed for easy troubleshooting. _Top of page_ ----------------------------------------------------------------------------
