Vszerda PCIe x16 to 4-Port U.2 NVMe Adapter Card PCIe 4.0 SFF-8643/8639

PCIe x16 to four U.2 NVMe adapter

This adapter converts a single PCIe x16 slot into four U.2 ports for NVMe drives. It targets system builders who need high-density enterprise storage in a workstation or server chassis. The card requires a motherboard that supports PCIe bifurcation to split the x16 link into four x4 lanes. Without that feature the additional ports will not function.

SFF-8643 connectors with LED status

Four SFF-8643 connectors provide the U.2 interface and the board is built from standard PCB material for rigidity. An onboard LED indicator shows link activity so administrators can verify drive status at a glance. The low-profile bracket fits 2U rackmount enclosures and the plug-and-play design needs no extra drivers or power cables.

Upgrades from single U.2 or M.2 carrier cards

Replaces single-port U.2 adapters or M.2 riser cards when four enterprise drives must share one full-length slot. The jump is worthwhile when the platform supports PCIe 4.0 bifurcation and the workload demands the aggregate bandwidth of four x4 NVMe devices. Buyers without bifurcation support or with only x8 electrical slots cannot use all four ports.
