PCI Express X16 to Dual MCIO 8i NVMe Adapter

Supports up to 4 PCle devices or NVMe SSDs compatible with PCle Gen5, Gen4, and Gen3

Connect directly to the U.2 NVMe SSD via an MCIO-to-SFF-8639 cable, supporting four x4 data link configurations (supported by both CPU and BIOS). Supports dual-channel x8 data link width configuration (supported by both CPU and BIOS). It features two built-in MCIO8i connector groups with pin definitions defined by SFF-9402.

The LRFN9A12 is a high-performance, low-loss interface conversion card that converts two MCIO interfaces through a PCIe5.0 x16 interface, connecting to either an NVMe SSD or a PCle interface. Its bandwidth matches the maximum capacity of the motherboard's PCle slot.

Motherboards with CPU and BIOS must support split functionality to ensure the PCle x16 link width can split into two x8 link widths or four x4 link widths for NVMe SSDs. Otherwise, the card will only support PCle x16 link width.

The adapter can run or communicate with connected NVMe drives without requiring a driver. The host sees the drive as a native device and uses the native NVMe driver.
