Shenzhen Lianrui Information Technology LRNV9F24 PCIe 4.0 x16 to Two SlimSAS SFF-8654 8i Retimer Adapter
Connects up to four PCIe 4.0 U.2 NVMe SSDs via two SlimSAS SFF-8654 8i ports using a retimer on a PCIe 4.0 x16 slot
- TypePCI Express Controller Card
- Connect four U.2 NVMe SSDs via two SlimSAS SFF-8654 8i ports
- PCIe 4.0 x16 host interface with retimer for signal integrity
- Requires motherboard and BIOS bifurcation to split x16 into quad x4 links
- Uses standard 100 MHz reference clock with optional clock output
- Direct cabling to U.2 drives through SFF-8654 to SFF-8639 cables
PCIe 4.0 x16 Retimer Adapter
This PCIe 4.0 x16 add-on card uses a retimer to maintain signal integrity across two SlimSAS SFF-8654 8i ports. It targets server, storage appliance and hardware accelerator builds that need to connect high-speed U.2 NVMe SSDs. The card requires a motherboard and BIOS that support bifurcation to split the x16 link into multiple lanes. Without that support the link remains at x16 width.
Dual SlimSAS Ports Enable Four U.2 Drives
Each SlimSAS SFF-8654 8i connector carries two x4 links so the adapter can host up to four PCIe 4.0 U.2 NVMe SSDs when paired with SFF-8654 to SFF-8639 cables. The retimer regenerates the 100 MHz reference clock and supports clock output to keep timing stable across the longer cable runs typical in dense enclosures. Bifurcation must be configured as quad x4 or dual x8 depending on the drive count.
Standard BGA Retimer in a Low-Profile Bracket
The retimer is mounted on a standard BGA package and the card fits a low-profile bracket for space-constrained chassis. Two SlimSAS ports face the rear so cables route cleanly toward backplane bays. Builders who need more than four U.2 drives or who cannot enable bifurcation in firmware will not be able to use the full capability of this adapter.

Jautājumi par šo preci
Will the LRNV9F24 retimer itself need firmware updates or replacement over time?
The adapter uses a PCIe 4.0 retimer with a standard 100 MHz reference clock and does not expose a user-serviceable firmware interface, so no routine retimer maintenance is expected.
What limits sustained throughput first — the PCIe 4.0 x16 host link or the two SlimSAS SFF-8654 8i connectors?
Each SlimSAS SFF-8654 8i connector carries eight lanes, matching the bifurcated x8 or quad x4 paths from the x16 slot, so neither the retimer nor the connectors impose a lower ceiling than the host link.
How much heat and noise does the card add when driving four U.2 NVMe SSDs all day?
The retimer operates from the slot's 100 MHz reference clock without an onboard fan, so added heat is limited to the retimer's own dissipation and noise stays at the system's existing airflow level.
