HP NC7170 Dual Port PCI-X 1000T Gigabit Server Adapter - Overview

Product Description

HP NC7170 Dual Port PCI-X 1000T Gigabit Server Adapter
The NC7170 is HP's first dual port PCI-X Gigabit Server Adapter for environments using twisted-pair cabling.

Gigabit Throughput Combined with Legacy Ethernet Support
A 1000Mbps Ethernet transfer rate delivers outstanding network performance that improves response time and removes bottlenecks. Because the NC7170 supports both 10Mbps Ethernet and 100Mbps Fast Ethernet in addition to Gigabit Ethernet, users are guaranteed end-to-end protocol support across their enterprise.
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 NC7170 features 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 NC7170 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 NC7170 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 Offloading Capability
TCP/IP is the protocol used in Ethernet transmissions; and typically the network’s TCP/IP segmentation and transmission are done by the operating system's protocol stack. The advanced capabilities of the NC7170 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.

  • Large Send Offloads/TCP Segmentation Offloads are capabilities that allow the TCP 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 Moderation is a feature that groups multiple packets, thereby reducing the number of interrupts sent to the host. This process optimizes host efficiency, leaving the CPU available for other duties.

PCI-X Support for Traditional PCI slots
PCI-X technology ensures hardware investment protection by retaining backward compatibility with the standard PCI bus architecture at the device and driver level. When the NC7170 is used in a traditional 64/100, 64/66, 64/33, or 32/33 PCI IO slot, its performance is limited to the maximum of the conventional bus architecture.
Dual Ports
Two Gigabit ports allow users to save slots in situations where their servers are slot-constrained. HP has long been an advocate of dual port adapters for servers; the NC7170 is the latest in our legacy of best-of-breed dual port devices for ProLiant servers.
Network Fault Tolerance (NFT PCI Hot Plug
Network Fault Tolerance, sometimes called "failover" or "NIC Redundancy," allows for the installation of multiple NC7170 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 NC7170 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.
Distance capabilities
The NC7170 supports cable runs up to 100 meters (328 feet).
The NC7170 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.
The NC7170 provides Wake-on-LAN (WOL) support through the PCI bus. A system that supports Wake on LAN can remain available to a systems administrator during its normal downtime. Once the machine is awakened, the systems administrator can remotely control, audit, debug, or manage the machine.
Management Support
Like all ProLiant server adapters, the NC7170 ships with drivers and agents that can be managed from all versions of Insight Manager. Additionally, it supports any management application that supports SNMP.
Server Integration
The SmartStart configuration utility includes setup support for the NC6170 so that the adapter can be configured as part of the SmartStart configuration process. Insight Manager can recognize the NC6170 individually or in a port-bonded team, and it can collect and report SNMP statistics on the adapter events. Integrated Management Log (IML) support is provided by the NC6170 for critical event logging on ProLiant servers.
Configuration Utilities
Each NC7170 ships with a suite of OS-tailored configuration 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 Server 2003 and Windows 2000 operating systems.
LED Indicators
Bracket LED indicators show link integrity, network activity, and speed on each port for easy troubleshooting.
