Description
Product Overview about the Dell 4KF8J
The 4KF8J Dell Qlogic Fastlinq QL41262 is a network adapter card used for high-speed network connectivity. It is a dual-port 25/10GBE SFP28 RNDC, which means it has two ports that support 25 gigabit Ethernet and 10 gigabit Ethernet connections using SFP28 transceivers. In this article, we will explain in detail what each of these terms means and how they are relevant to the 4KF8J Dell Qlogic Fastlinq QL41262 network adapter card.
Network Adapter Card
A network adapter card is a hardware component that is used to connect a computer or server to a network. It is also called a network interface card (NIC). The network adapter card is responsible for converting digital data from the computer into signals that can be transmitted over a network cable or wireless connection. It also receives signals from the network and converts them back into digital data that can be processed by the computer.
Dual-Port
The 4KF8J Dell Qlogic Fastlinq QL41262 is a dual-port network adapter card. This means that it has two ports that can be used to connect the card to a network. Having two ports allows for increased network redundancy and load balancing. If one port fails or becomes overloaded, the other port can take over, ensuring that network connectivity is not lost. Load balancing can also be achieved by distributing network traffic across both ports, which can result in faster and more efficient data transfer.
25/10GBE
The 4KF8J Dell Qlogic Fastlinq QL41262 supports both 25 gigabit Ethernet (25GBE) and 10 gigabit Ethernet (10GBE) connections. Ethernet is a technology used for local area networks (LANs). It defines the physical and data link layer specifications for communication between devices on a network. The speed of Ethernet connections is measured in gigabits per second (GBE). 25GBE is a faster and more modern Ethernet standard compared to 10GBE. It provides faster data transfer rates and lower latency, making it ideal for high-performance computing and storage applications.
SFP28
The 4KF8J Dell Qlogic Fastlinq QL41262 uses SFP28 (small form-factor pluggable 28) transceivers to connect to the network. SFP28 is a high-speed optical transceiver that is used to transmit and receive data over optical fiber cables. It is an upgrade from SFP+ (small form-factor pluggable plus) transceivers, which were used for 10GBE connections. SFP28 transceivers support data transfer rates of up to 28 gigabits per second, which is higher than SFP+ transceivers. They are also backward compatible with SFP+ transceivers, which means that they can be used in SFP+ ports.
RNDC
RNDC stands for rack network daughter card. It is a type of network adapter card that is designed for use in servers. It is installed on the motherboard of the server and provides network connectivity for the server. RNDC cards are often used in high-performance computing environments where fast and reliable network connectivity is essential.
Overall, the 4KF8J Dell Qlogic Fastlinq QL41262 is a high-performance network adapter card that supports both 25GBE and 10GBE connections using SFP28 transceivers. It is a dual-port card, which provides increased network redundancy and load balancing. The card is designed for use in servers and is installed as an RNDC card.
