Product Overview of the HPE 647594-B21 Ethernet Network Adapter

In the world of networking, having reliable and efficient network adapters is crucial for seamless communication and data transfer. One such component that stands out is the HPE 647594-B21 Ethernet 1GB 4-Port 331T PCI-E Plug-in Card Network Adapter. In this comprehensive guide, we will delve into the intricate details of this network adapter, exploring its features, benefits, installation process, and the impact it can have on your network infrastructure.

Understanding the Basics

The HPE 647594-B21 is a network adapter designed to provide high-speed Ethernet connectivity with four ports. Ethernet, in the context of networking, is a standard for connecting computers and other devices in a local area network (LAN). The '1GB' in the name denotes the data transfer speed, which is 1 gigabit per second. The '4-Port' indicates that this adapter has four separate ports, allowing it to handle multiple connections simultaneously. The '331T' signifies its model number.

PCI-E Plug-in Card

The term "PCI-E" stands for Peripheral Component Interconnect Express, which is a high-speed serial computer expansion bus standard. In the case of the HPE 647594-B21, it is a plug-in card, meaning it can be easily inserted into a compatible PCI-E slot on a server or computer motherboard.

Key Features of HPE 647594-B21 Ethernet 1GB 4-Port 331T PCI-EHigh-Speed Connectivity

The primary feature of this network adapter is its capability to deliver high-speed connectivity at 1 gigabit per second. This is especially beneficial in scenarios where large volumes of data need to be transferred quickly and efficiently, such as in data centers or enterprise-level networks.

Four-Port Configuration

The inclusion of four ports sets the HPE 647594-B21 apart from single or dual-port adapters. This feature allows for increased flexibility in network configurations, facilitating load balancing and redundancy. Multiple ports also enable the adapter to handle a higher number of concurrent connections, improving overall network performance.

Energy-Efficient Design

In line with modern sustainability practices, the HPE 647594-B21 is designed with energy efficiency in mind. It incorporates power-saving features that help reduce overall energy consumption, contributing to lower operational costs and a smaller environmental footprint.

Advanced Network Offload Capabilities

This network adapter is equipped with advanced offload capabilities, which means that certain network-related tasks can be processed directly by the adapter rather than the host system's CPU. This offloading mechanism enhances overall system performance by reducing the workload on the CPU and improving the efficiency of data transfers.

Scalability and Future-Proofing

With its four-port configuration and high-speed capabilities, the HPE 647594-B21 is designed to accommodate the growing demands of evolving network environments. Its scalability ensures that it can meet the requirements of expanding networks, providing a certain level of future-proofing for organizations looking to invest in long-term network solutions.

Benefits of Using HPE 647594-B21 Ethernet 1GB 4-Port 331T PCI-E

Improved Network Performance

The high-speed connectivity and advanced features of the HPE 647594-B21 contribute to a significant improvement in network performance. Faster data transfers, reduced latency, and efficient load balancing result in a network that can handle the demands of modern applications and services.

Enhanced Reliability

The inclusion of four ports not only allows for increased capacity but also enhances the reliability of the network. In the event of a port failure or network congestion, the additional ports provide redundancy and ensure uninterrupted connectivity, minimizing the risk of downtime.

Simplified Network Management

The plug-and-play nature of the PCI-E plug-in card simplifies the installation and management of the network adapter. This is particularly advantageous for IT administrators who need to deploy and maintain network infrastructure efficiently. The adapter's compatibility with existing systems further streamlines the management process.

Cost-Effective Solution

While providing advanced features, the HPE 647594-B21 offers a cost-effective solution for organizations seeking to upgrade their network capabilities. Its energy-efficient design also contributes to cost savings over the long term by reducing power consumption.
