Hardware and Software Requirements

To install and use the 376158-B21 HP NC570C PCI-X Dual Ports Fabric Adapter Network Interface Card, the following hardware and software requirements must be met:

  • Compatible server: The adapter is designed for use with HP ProLiant servers, including the DL, ML, and BL series. Check the compatibility list on the HP website to ensure that the adapter is compatible with your specific server model.
  • Available PCI-X slot: The adapter requires an available PCI-X slot in the server. Check your server's documentation to determine if it has a compatible slot available.
  • Operating system: The adapter is compatible with a range of operating systems, including Windows Server, Linux, and VMware. Check the HP website to ensure that the specific version of your operating system is supported.
  • Drivers: The adapter requires specific drivers to function properly. These can be downloaded from the HP website, and it's important to ensure that the correct driver version is installed for your operating system.
  • Firmware: The adapter may require firmware updates to ensure optimal performance and compatibility. Check the HP website for the latest firmware updates, and follow the instructions provided to install them.
  • Network infrastructure: The adapter requires a compatible network infrastructure, including switches and cabling. Check the HP website to ensure that the adapter is compatible with your network infrastructure.
  • Power supply: The adapter may require additional power beyond what is supplied by the server's PCIe slot. Ensure that the server has a compatible power supply that can provide the necessary power to the adapter.

Performance and Reliability

The 376158-B21 HP NC570C PCI-X Dual Ports Fabric Adapter Network Interface Card is designed to provide high performance and reliability for enterprise-level networks. Here are some of the key factors that contribute to its performance and reliability:

  • Dual-port design: The adapter features dual ports, which allows for increased bandwidth and network redundancy. This means that if one port fails, the other port can take over, ensuring that the network remains operational.
  • 10 Gbps bandwidth: The adapter supports up to 10 Gbps of bandwidth, which is ideal for demanding enterprise-level applications that require high network throughput. This allows for faster data transfer and reduces network congestion.
  • Fibre Channel over Ethernet (FCoE) support: The adapter supports FCoE, which allows for the transmission of Fibre Channel traffic over Ethernet networks. This provides a cost-effective way to consolidate storage and network traffic onto a single adapter.
  • Jumbo frame support: The adapter supports jumbo frames, which allows for the transmission of larger data packets. This reduces the overhead of the network and can improve network performance.
  • Quality of Service (QoS) support: The adapter supports QoS, which allows for the prioritization of network traffic. This ensures that critical network traffic, such as VoIP or video streaming, is given priority over other network traffic, improving overall network performance.
  • Advanced error handling: The adapter features advanced error handling capabilities, such as intelligent interrupt coalescing and packet buffering, which can help reduce packet loss and improve network performance.
  • Redundant firmware: The adapter features redundant firmware, which provides an additional level of reliability and fault tolerance. If one firmware image becomes corrupted, the adapter can automatically switch to the backup image, ensuring that the adapter continues to function properly.
  • Built-in diagnostics: The adapter features built-in diagnostics that can help identify and diagnose network issues. This can help reduce downtime and improve overall network reliability.

Compatibility with Operating Systems

The 376158-B21 HP NC570C PCI-X Dual Ports Fabric Adapter Network Interface Card is compatible with a range of operating systems, including:

  • Windows Server: The adapter is compatible with various versions of Windows Server, including Windows Server 2003, Windows Server 2008, and Windows Server 2012.
  • Linux: The adapter is compatible with a range of Linux distributions, including Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and Ubuntu.
  • VMware: The adapter is compatible with VMware ESX and ESXi, which allows it to be used in virtualized environments.

It's important to ensure that the specific version of the operating system is supported by the adapter, as well as the corresponding drivers and firmware. Drivers for the adapter can be downloaded from the HP website, and it's important to ensure that the correct driver version is installed for the specific operating system being used.

In addition to operating system compatibility, the adapter is also compatible with various management and monitoring tools, including HP Systems Insight Manager, HP Insight Control, and SNMP. These tools allow for remote management and monitoring of the adapter, which can help improve network performance and reliability.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Adding gigabyte network connectivity is one of the best decisions users can make in the modern world. This is what the NIC (Network Interface Card) offers. This highly advanced networking device offers users a dedicated computer network connection.

The network interface card's ability to support wired and wireless network communications makes it one of the best choices. Individual users and IT professionals will find them very useful.

NIC enables adequate communication between computers. The computers may either be connected over a Local Area Network or over larger-scale networks via an IP. Regardless of the connection type, the network interface card offered at AllHDD works at optimal rates.

When users choose network interface card options here, they get the most reliable hardware circuitry. That is, there's a synergy between a data link and a physical layer in one device. The circuitry enables the physical layer to process data so that the processes involving the data link layer can run effectively on it.

Gone are the days when network controllers were the real deals. Today, a network interface card can serve as an expansion module in computer systems or routers. The specifications of the NIC users will get correspond with the standard of various network options.

Network Interface Card Options

Internal Network Interface Cards

Users will find NIC (Network Interface Cards) that users can insert directly onto the computer's motherboard. For these options to offer network access, there's the need for network cables. There are NIC options that use connections like Peripheral Component Interconnect (PCI). Others connect with Industry Standard Architecture (ISA).

External Network Interface Cards

Laptops and desktops which do not come with an internal network interface card use the external option. There are two options for the external NIC. The first is the wireless network cards, which will be attached directly to the motherboard.

Unlike the internal option, there will be no need for networking cables in this case. These options are the best when users need to travel or access wireless signals.

On the other hand, there are several USB options ranging from 1 port to 4 port NIC. They are compact, and they add a network connection to a USB-enabled computer system. Many of these NIC options work with 10-100-1000 Mbps networks.

They are also ideal replacements for local area network (LAN) adapters and similar laptop accessories. Users will find USB network interface cards that support features such as VLAN tagging, Jumbo Frames, and Wake on LAN (WOL). They are the most reliable Gigabit network for versatile home and business use.

Key Features

  • Fast and Reliable Performance. The network interface cards have impressive speed ratings with options up to 1000 Mbps. They enable the connection of multiple computers without the fear of failure.
  • Updated and Incorruptible Driver. The driver that passes data between the NIC and the computer system ensures optimal performance.
  • Connectivity LED. These NIC (Network Interface Cards) come with integrated LED indicators to notify users when there is a network connection and transfer of data.
