Description
The Lenovo 81Y3520, part of the X710 adapter family, is a high-performance dual-port 10 Gigabit Ethernet network adapter specifically designed for integration into Lenovo ThinkSystem servers. This adapter card provides two SFP+ (Small Form-Factor Pluggable Plus) ports, enabling robust and high-speed network connectivity essential for demanding enterprise workloads. The 10GbE speed per port is critical for applications requiring high throughput, such as large data transfers, storage area networks (SANs), virtualization, and high-performance computing (HPC) environments. Featuring a PCIe Gen 3.0 x8 interface, the 81Y3520 ensures ample bandwidth to support the full 10 Gbps data rate for both ports concurrently, minimizing bottlenecks between the network and the server's processing capabilities. The adapter is engineered to deliver reliable performance and low latency, crucial for maintaining application responsiveness and data integrity. It supports advanced features like Single Root I/O Virtualization (SR-IOV), which enhances virtual machine performance by providing direct hardware access, thereby reducing CPU utilization and improving I/O efficiency. This adapter is optimized for Lenovo ThinkSystem servers, ensuring seamless compatibility and integration with the server's hardware and management software. The dual-port configuration offers flexibility for network redundancy, load balancing, or connecting to separate networks. The Lenovo 81Y3520 is a key component for building high-performance, scalable, and resilient network infrastructures within data centers and enterprise IT environments.
