CNS41PE08L is a PCIe 4.0 X8 to 1*SFF-8654 8i NVMe adapter card. It adopts the PCIe 4.0 X8 bus type and requires the motherboard BIOS to support channel splitting. Through the SFF-8654 8i to 2*SFF-8639 cable, it can connect 2 NVMe U.2 hard drives. This card is applied in high-performance scenarios such as data centers and enterprise-level storage.
Product Features：
1. The motherboard BIOS must support UEFI mode, and the operating system must support NVMe mode. This card can be paired with the SFF-8654 to PCIE RISER card, and through an 8654 cable, it can expand the PCIE X8 slot.
2. The ports support PCIe 4.0, and are backward compatible with PCIe 3.0 and PCIe 2.0.
3. This card requires the motherboard BIOS to support the X4X4 split mode in order to support the simultaneous connection of two U.2 NVMe hard drives. Many server motherboards produced by manufacturers such as Supermicro, TaiShan, ASUS, MSI, and Gigabyte have BIOS that support PCIe splitting. Please contact the motherboard manufacturer's customer service for specific inquiries.
