PCI Network Adapter
A PCI Network Adapter is a hardware device that enables a computer to connect to a network via a physical connection such as Ethernet, fiber optic, or InfiniBand. It is installed into an available PCI slot on the motherboard of a desktop or server computer, and typically consists of a small printed circuit board with one or more network ports.
The PCI Network Adapter allows a computer to communicate with other devices on the same network, including other computers, servers, printers, and storage devices. It provides the necessary physical layer and data link layer functionality to transmit and receive data over the network.
PCI Network Adapters are available in various speeds ranging from 10 Mbps to 100 Gbps, and may support various network protocols such as TCP/IP, UDP, and ICMP. They may also offer advanced features such as Quality of Service (QoS), VLAN tagging, and virtualization.
PCI Network Adapters are widely used in enterprise networks, data centers, and cloud computing environments to connect servers and other network devices to the network. They are often preferred over onboard network interfaces on the motherboard due to their faster speeds, better performance, and ability to support more advanced networking features.
The system requirements for HPE InfiniBand EDR Single-Port 100Gbps Network Adapter are as follows:
- Compatibility: The network adapter is compatible with servers and workstations that have PCI Express 3.0 x8 slots.
- Operating System: The network adapter is supported by various operating systems such as Windows Server 2016 and 2019, Red Hat Enterprise Linux 7.6 and 8.0, SUSE Linux Enterprise Server 12 and 15, and VMware ESXi 6.7 and 7.0.
- Processor: The system should have a compatible processor that meets the minimum requirements for the operating system.
- Memory: The system should have sufficient memory to support the operating system and applications that use the network adapter.
- Power Supply: The system should have a power supply that can support the network adapter and other components in the system.
- Network Connectivity: The network adapter requires an InfiniBand network infrastructure to function properly. This includes InfiniBand switches and cables that are compatible with the network adapter.
- Driver Software: The system should have the appropriate driver software installed for the network adapter to function properly. The driver software can be downloaded from the HPE website.
It is important to ensure that the system meets these requirements before installing the HPE InfiniBand EDR Single-Port 100Gbps Network Adapter to ensure optimal performance and compatibility.
Maintenance and Troubleshooting
Maintenance and troubleshooting are important aspects of managing the HPE InfiniBand EDR Adapter to ensure its optimal performance. Here are some tips for maintaining and troubleshooting the adapter:

A network adapter also called a network interface card is a plug-in card that serves to allow computers to both transmit and receive data on a local network. It is a component of a computer's internal hardware that facilitates communication over a network.
In a more current context, network adapters will refer to an Ethernet adapter where the Ethernet circuitry is built into motherboards of the latest desktops and laptop computers. Other times, a network adapter may also refer to a wireless (Wi-Fi) adapter.
In all instances, the adapter allows a computer to connect with another computer, a server, or other networking devices through a LAN connection. The use of a network adapter is not limited to wired connections as it is used for wireless networks. The adapters for wired networks come with an RJ-45 port that may use either the twisted or untwisted pair cables for network connectivity. For the wireless adapters, the network connection is facilitated through a built-in antenna or an externally connected antenna. Both the wired and wireless network adapters support the popular LAN protocols including TCP/IP. We have 1-port, 2-port, 4-port, 6-port, 8-port, and 16-port options that support speeds of 10, 25, 40, or even 100 Gigabits.
The plug-in network interface cards (NICs) are normally used in high-performance machines especially if a faster Ethernet standard is relatively new and available but is yet to become mainstream. In fact, the major difference between network adapters lies in the network protocol it supports.
We have the different types of network adapters necessary for building computer-to-computer networks that don't have a switch or hub. All the network adapters are fairly inexpensive and readily adaptable to different applications within a network. Some of the common types available are:
Network adapters common types
- Desktop Network Interface Card: This adapter is usually connected to a PCI or PCIe slot, whichever is available on the motherboard of your desktop computer. You will need to open your computer's case and it, therefore, presents the most difficult installation method. The PCIe slot is generally found in new computers.
- PC Card or PCMCIA Card: PCMCIA is the abbreviation for Personal Computer Memory Card International Association. The name has undergone changes over time to be referred to as a PC Card or ExpressCard. For dimensions, the PC card is almost similar in size to a credit card but is significantly thicker. The PC card is connected to a PC or PCMCIA card slot in your desktop computer or laptop computer.
- USB adapter: This network adapter is typically a small device, similar to a thumb drive, with a USB interface. Installation is easy and straightforward since it is plugged into the USB port of your desktop or laptop computer or other network devices that have a USB port.
- Wireless game adapters also referred to as media adapters, are connected to older game consoles and home entertainment devices so as to act as a bridge to Wi-Fi capability. They help expand functionality on these entertainment devices through connections to the internet.
