Product Description
The IBM 49Y4221 is a robust 4-port Gigabit Ethernet Network Adapter designed to deliver high-speed and reliable network connectivity for enterprise-level servers and high-performance workstations. Each of the four RJ-45 ports supports 1000Base-T standards, providing a full 1 Gigabit per second (Gb/s) bandwidth per port. This makes it an excellent choice for environments with significant network traffic, such as data centers, virtualization hosts, and demanding client machines. Utilizing a PCI Express (PCIe) x4 interface, this network card ensures ample bandwidth to support all four Gigabit Ethernet ports operating at full duplex simultaneously without becoming a bottleneck. The PCIe x4 interface is designed for high-throughput applications, making it well-suited for modern server architectures. It supports advanced features like jumbo frames and TCP/IP offloading to further enhance network performance and reduce CPU utilization. This network card is a critical component for expanding network capabilities, offering a high-density solution for server consolidation, network segmentation, or providing multiple high-speed network connections. Its design prioritizes stability and performance, making it a dependable choice for mission-critical network infrastructure where uptime and speed are paramount.
