IBM 81Y9990 2-Port 10Gb/s SFP+ PCIE x8 GE 10GBase-SR Network Adapter

Product Description

The IBM 81Y9990 is a high-performance dual-port 10 Gigabit Ethernet (10GbE) network adapter designed to provide high-speed connectivity for servers and workstations. It features two SFP+ (Small Form-factor Pluggable Plus) ports, allowing for flexible fiber optic connections. The adapter utilizes the 10GBase-SR standard, which is optimized for short-reach connections over multi-mode fiber optic cables, typically up to 300 meters, making it ideal for data center environments and high-performance computing clusters. This network adapter connects to the host system via a PCIe x8 interface, providing ample bandwidth to support the demanding throughput of 10GbE speeds. Its design ensures efficient data transfer and low latency, crucial for applications such as storage area networks (SANs), high-frequency trading, and large-scale data processing. The dual-port configuration offers redundancy and increased throughput capabilities, enhancing network resilience and performance. Designed with enterprise requirements in mind, the IBM 81Y9990 is built for reliability and compatibility within IBM server environments, though it is often compatible with other server platforms. It typically comes with support for advanced features like TCP/IP offload, jumbo frames, and virtualization technologies, further optimizing network performance and reducing CPU utilization. The inclusion of a low-profile bracket makes it suitable for installation in a variety of server chassis types.
