OCP 3.0 dual-port 25G SFP28 network adapter for cloud and data center infrastructure.
Scaling network throughput in dense cloud servers often creates bottlenecks when traditional PCIe cards consume valuable expansion slots. The LRES3040PF-OCP addresses this by leveraging the OCP 3.0 standard, delivering high-density connectivity without sacrificing slot availability for GPUs or storage controllers.
With dual 25G SFP28 ports, this adapter provides up to 50Gbps of aggregate bandwidth, enabling low-latency communication for distributed databases and analytics platforms. Its hardware-based stateless offload engine effectively handles NVGRE and VXLAN encapsulation, which eliminates CPU overhead and ensures consistent performance under heavy virtualized traffic loads.
Ideal for Web 2.0, cloud computing, and storage platforms, the LRES3040PF-OCP supports SR-IOV to guarantee resource isolation for virtual machines. This solution reduces cabling complexity and enhances server utilization, making it a cost-effective choice for modern data center deployments requiring reliable 1/10/25G connectivity.
Designed for OCP 3.0 SFF form factor, optimizing space in modern cloud servers.
Dual-port 25G SFP28 interfaces support 1/10/25Gbps data rates for flexible networking.
Native support for NVGRE, VXLAN, and GENEVE offloading reduces host CPU load.
Provides dedicated adapter resources for VMs, ensuring isolation and improved utilization.
Supports IEEE 802.3az Energy Efficient Ethernet to reduce power consumption.
High-quality optical modules and cables for optimal compatibility with your network adapter.
