Green circuit board with two silver SFF-8643 ports and a gold PCIe x8 edge connector

eshinreal

eshinreal 2-Port PCIe 3.0 x8 to SFF-8643 NVMe Switch Card (PLX8747)

SKU CH-6VYW-V3RXK

Adds two SFF-8643 ports for NVMe U.2 SSDs over a PCIe 3.0 x8 link using a PLX8747 switch

  • Product typeController Card
  • Dual SFF-8643 ports connect two U.2 NVMe SSDs via breakout cables
  • PCIe 3.0 x8 host interface delivers eight lanes of Gen3 bandwidth
  • PLX8747 switch chip provides non-blocking, low-latency switching between drives
  • Flexible lane allocation supports x4x4 bifurcation or single x8 device mode
  • Passive cooling and LED status indicators ensure enterprise-grade reliability from 0°C to 70°C

Dual-Port NVMe Switch Card

The eshinreal controller card adds two SFF-8643 ports to a PCIe 3.0 x8 slot, letting servers and workstations attach a pair of U.2 NVMe SSDs through Mini-SAS HD breakout cables. A Broadcom PLX8747 switch chip handles lane allocation in x4x4 or single x8 modes without blocking bandwidth between the drives.

Enterprise Storage Expansion

This card suits administrators who need to connect two U.2 NVMe drives to a single x8 link in a rack server or high-end workstation. Builders who only have x4 slots, who require more than two drive connections, or who need active cooling for sustained heavy loads should look at other solutions.

PLX8747 Switch Chip

The onboard Broadcom PLX8747 PCIe switch enables non-blocking, low-latency switching across the two SFF-8643 ports, delivering the flexible lane allocation that determines whether both NVMe SSDs can operate at full x4 speed simultaneously.

Questions about this item

Do I need breakout cables to connect U.2 NVMe SSDs to the SFF-8643 ports?

Yes, the dual SFF-8643 (Mini-SAS HD) ports require SFF-8643 to SFF-8639 breakout cables to attach U.2 NVMe drives.

Will this card bifurcate its PCIe 3.0 x8 link into two x4 connections for my existing drives?

The PLX8747 switch chip supports flexible lane allocation, enabling x4x4 bifurcation so each NVMe SSD receives a dedicated PCIe 3.0 x4 link.

How can I confirm the card is operating correctly once installed?

LED status indicators on the bracket show link activity and drive presence, providing immediate visual confirmation of proper operation.
