The IBM 74Y3458 is a high-performance 10Gb 2-Port PCIe2 (x8) Ethernet Short Range (SR) Adapter designed to fit in low-profile (LP) slots, offering a powerful solution for enhancing network connectivity in enterprise-grade servers. This adapter utilizes PCIe Generation 2 interface technology for high-speed data transmissions and integrates two 10 Gigabit Ethernet ports for network communication, effectively doubling the network bandwidth available to the server. Its SR capability means it is optimized for short-range connections, using multimode fiber to achieve lower latency and high transfer speeds within data center environments. The 74Y3458 is particularly useful for applications requiring high bandwidth and network performance, such as virtualization, high-performance computing, and cloud services. Its low-profile design makes it an ideal choice for compact servers where space is at a premium, offering a balance between form factor and performance. With support for advanced networking features such as VLAN tagging, Quality of Service (QoS), and link aggregation, the IBM 74Y3458 10Gb Ethernet SR Adapter provides a robust, scalable networking solution that meets the demands of modern data center operations and enterprise networks.
