High-performance OCP 3.0 dual-port 25G Ethernet adapter for data centers.
When network congestion causes application timeouts in AI training clusters, every microsecond of latency matters. The LRES4150PF-2SFP28 OCP 3.0 network adapter addresses this by delivering ultra-low latency and high bandwidth for latency-sensitive workloads in space-constrained server environments.
With dual SFP28 interfaces supporting up to 25Gbps per port, the card provides 50Gbps aggregate bandwidth, enabling rapid data transfer for large-scale analytics. Its PCIe 3.0 x16 host interface ensures robust connectivity, while hardware offloads like TCP/UDP/IP stateless offload and Open vSwitch (OVS) significantly reduce CPU utilization, enhancing overall system efficiency.
Designed for enterprise and cloud-scale deployments, this adapter supports RoCEv2 and IEEE 1588 PTP, making it perfect for HPC and telecommunications infrastructure. By minimizing CPU usage and maximizing throughput, the LRES4150PF-2SFP28 helps data centers reduce operating costs while maintaining high performance.
Fully compliant with OCP 3.0 mechanical specifications in a compact Small Form Factor (SFF), ideal for space-constrained data center deployments.
Features dual SFP28 optical ports supporting up to 25Gbps per port for high-speed optical transmission and reduced latency.
Supports TCP/UDP/IP stateless offload, checksum offload, LSO, LRO, RSS, and Open vSwitch (OVS) hardware offload to minimize CPU usage.
Supports RoCEv2 (RDMA over Converged Ethernet) for ultra-low latency and high bandwidth, improving performance for latency-sensitive workloads.
Built-in support for IEEE 1588 PTP v1 & v2 ensures precise synchronization for telecommunications and industrial applications.
Includes SR-IOV, UEFI, WoL, NCSI, and Hot Swap support for flexible deployment in virtualized and cloud environments.
High-quality optical modules and cables for optimal compatibility with your network adapter.
