High-performance PCIe 5.0 x16 to dual MCIO 8i NVMe adapter for direct U.2 SSD connection.
Scaling high-speed storage in PCIe 5.0 servers often requires complex cabling and bandwidth management. The LRFN9A12 solves this by converting a single PCIe 5.0 x16 slot into dual MCIO 8i interfaces, enabling direct, low-loss connections to multiple NVMe SSDs without bottlenecking the host bus.
With support for PCIe Gen5, Gen4, and Gen3, the adapter delivers maximum motherboard slot capacity. It features two built-in MCIO 8i connectors (SFF-9402) that can split the x16 link into dual x8 or quad x4 configurations. This flexibility ensures optimal bandwidth distribution for high-performance storage arrays, eliminating the need for proprietary drivers as the host recognizes drives natively.
Ideal for data centers and AI clusters requiring dense, high-throughput NVMe storage, the LRFN9A12 leverages standard MCIO-to-SFF-8639 cabling for U.2 SSD integration. Its compact design and broad compatibility with CPU/BIOS split functionality make it a robust solution for modern enterprise storage expansion.
Connects via PCIe 5.0 x16 slot, supporting backward compatibility with Gen4 and Gen3 for maximum bandwidth utilization.
Features two MCIO 8i connectors (SFF-9402) allowing flexible split into dual x8 or quad x4 links for multiple NVMe SSDs.
Operates without additional drivers; the host system recognizes connected drives using the native NVMe driver for plug-and-play ease.
Supports up to 4 PCIe devices or NVMe SSDs, ideal for scaling storage capacity in data center and AI training environments.
