Dual-port 25G SFP28 NIC based on Intel E810 with RDMA support.
When network congestion causes application timeouts in AI training clusters or cloud storage environments, every microsecond of latency matters. The LRES1021PF-2SFP28 addresses this by providing dedicated application queues that prevent data confusion between workloads, ensuring predictable performance for critical services.
Built on the Intel E810 controller, this adapter delivers 25Gbps per port over dual SFP28 interfaces, providing 50Gbps aggregate bandwidth. This high throughput eliminates bottlenecks in high-performance computing and storage networks, while PCIe 4.0 x8 connectivity ensures maximum data transfer efficiency to the host system.
Ideal for data centers, cloud computing, and storage networks, the card features scalable ADQ technology to optimize thread-to-device data paths. With broad OS support including Windows Server, Linux, and VMware ESXi, it offers a reliable, low-latency solution for enterprise infrastructure requiring robust 25G connectivity.
Based on Intel E810 master program for broad compatibility and performance guarantees.
Supports 25Gbps data transmission rate per port for high throughput data center services.
Optional support for RDMA iWARP and RoCEv2 functions to reduce application latency.
Scalable ADQ technology improves performance scalability and predictability for critical workloads.
PCIe v4.0 x8 interface backward compatible with PCIe v3.0 & v2.0 for flexible deployment.
Supplemented with hardware accelerated packet processing extended features.
High-quality optical modules and cables for optimal compatibility with your network adapter.
