Description
Product Overview
In the world of computer networks, communication between devices plays a critical role. This communication is enabled through different network adapters, which are hardware components that allow a computer to connect to a network. One of these adapters is the IBM Qlogic 10GB PCI Express 2.0 X8 Converged Network Adapter, which is commonly known as the 42C1800. In this article, we will provide an in-depth explanation of this network adapter, its features, and how it can be used to enhance network communication.
Definition of Converged Network Adapter
A Converged Network Adapter (CNA) is a type of network adapter that enables network convergence. Network convergence is the concept of using a single network to carry different types of traffic such as data, voice, and video. In traditional networks, different types of traffic require separate networks, which can lead to increased costs, complexity, and management overhead. With a CNA, multiple types of traffic can be carried over a single network, reducing costs, and simplifying management.
Specification of Converged Network Adapter
The IBM Qlogic 10GB PCI Express 2.0 X8 Converged Network Adapter, or 42C1800, is a CNA designed for high-speed data transfer and network convergence. It is based on the PCI Express 2.0 standard, which provides a high-speed data transfer rate of up to 5 Gbps per lane. The 42C1800 has eight lanes, which means it can provide a maximum data transfer rate of up to 40 Gbps.
Features of the 42C1800 The 42C1800 is designed to provide high-performance networking capabilities, with a range of features that enhance its functionality. Some of the key features of the 42C1800 include:
- Dual-port connectivity: The 42C1800 has two ports, which can be used for different types of traffic. This enables redundancy and load balancing, ensuring that traffic is evenly distributed across the network.
- 10GB Ethernet: The 42C1800 supports 10 Gigabit Ethernet, which is a high-speed networking standard that provides a data transfer rate of up to 10 Gbps. This enables faster data transfer, which is particularly useful for data-intensive applications such as video streaming and data backup.
- iSCSI offload: The 42C1800 has built-in iSCSI offload capabilities, which offload the processing of iSCSI traffic from the server’s CPU to the adapter. This reduces CPU overhead and improves overall system performance.
- FCoE support: The 42C1800 supports Fibre Channel over Ethernet (FCoE), which enables the convergence of Fibre Channel and Ethernet networks. This can reduce costs and simplify network management by enabling the use of a single network for both types of traffic.
- Virtualization support: The 42C1800 supports virtualization, which enables the creation of multiple virtual servers on a single physical server. This enables more efficient use of server resources and reduces costs.
Benefits of the Traditional Network Adapters
- Faster data transfer: The 42C1800’s high-speed data transfer rate enables faster data transfer, which is particularly useful for data-intensive applications.
- Network convergence: The 42C1800 enables the convergence of different types of traffic over a single network, reducing costs and simplifying network management.
