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

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.
