eshinreal PCIe 3.0 x16 to Quad M.2 NVMe Adapter PLX8747 Low Profile

Quad M.2 NVMe PCIe 3.0 Adapter

This low-profile add-in card uses a PLX 8747 switch to split one PCIe 3.0 x16 slot into four independent M.2 NVMe ports. Each port runs at PCIe 3.0 x4 without requiring motherboard bifurcation support. The card fits 1U rack servers and compact workstations with its 64mm height and included half-height bracket.

Storage Expansion for Dense Servers

It suits administrators adding high-speed local storage to space-constrained 1U or 2U systems. Builders using motherboards without bifurcation capability benefit from the on-board switch. Systems lacking a free x16 slot or only offering x8 electrical links cannot use this adapter.

PLX 8747 Switch Enables Four Drives

The PLX 8747 bridge chip is the single specification that makes four simultaneous NVMe drives possible on a single slot. It presents each M.2 socket as a separate x4 endpoint to the operating system. Without this switch, four drives would require platform-level bifurcation.
