Dell Broadcom YY424 Mezzanine Card Description
The Dell YY424 Broadcom Dual-Port GBE Mezzanine Card is designed to expand network connectivity inside Dell enterprise servers and blade systems. Unlike standard PCIe NIC cards, this module connects directly to a dedicated mezzanine slot on the server motherboard or blade chassis, offering a compact and integrated networking solution.
It provides two independent Gigabit Ethernet ports, allowing redundancy, load balancing, and improved network reliability. This makes it ideal for environments where uptime and stable connectivity are critical, such as virtualization clusters, database servers, and enterprise application hosting.
The Broadcom-based controller ensures efficient packet processing with low CPU utilization, improving overall server performance under network-heavy workloads. When installed in supported Dell systems, the card is typically recognized through BIOS and iDRAC, allowing system-level monitoring and management integration.
This type of mezzanine card is commonly used in Dell PowerEdge blade infrastructure (M1000e) and select rack server configurations that support daughter card expansion.
