Dell 430-4459 x520-k 2-Ports 10Gb/s KR Blade Daughter Card for PE M820

Product Description

The Dell 430-4459, also known as the x520-k blade daughter card, is a specialized networking component designed exclusively for integration into the Dell PowerEdge M820 blade server. This card provides two 10 Gigabit Ethernet (GbE) ports, enabling high-speed network connectivity for the blade server within its chassis. The 'KR' designation in its interface specification refers to the 1000BASE-KR standard, which is commonly used for high-speed serial communication over printed circuit board traces, particularly in backplane applications within blade server systems. As a daughter card, the 430-4459 is designed to plug directly into a dedicated slot on the M820 server's motherboard or midplane. This form factor is crucial for blade architectures, allowing for dense server deployments where space is at a premium and internal cabling is minimized. The KR interface ensures efficient and high-bandwidth communication between the network card and the blade chassis's backplane, which then connects to the network fabric. This card is essential for environments that require significant network throughput from their blade servers, such as high-performance computing clusters, virtualization hosts, or data-intensive applications. By providing 10Gb/s connectivity, it ensures that the M820 blade servers can keep pace with the demands of modern networks and storage solutions, facilitating faster data transfers and improved application responsiveness within the blade infrastructure.
