PCIe 3.0 x8 NVMe switch adapter with 2x SFF-8643 and 2x SFF-8644 ports for external storage expansion.
Expanding high-speed storage in data centers often requires sacrificing valuable PCIe slots or relying on complex motherboard configurations that limit scalability. This adapter solves the bottleneck by providing a dedicated switching solution for NVMe drives.
Equipped with a PLX PEX8725 controller, the card splits PCIe 3.0 x8 bandwidth into four independent channels, delivering full line speed processing for all interfaces. It features two SFF-8643 ports for internal U.2 SSDs and two SFF-8644 ports for connecting external NVMe expansion cabinets, enabling flexible point-to-point communication modes.
Ideal for graphics applications and host-centric architectures, this adapter allows servers to connect to external PCIe protocol devices seamlessly. By offloading signal splitting to the card, it ensures compatibility with standard servers while maximizing storage density and performance for cloud computing and AI workloads.
PLX chip splits into four channels providing full line speed processing for all interfaces.
Features 2x SFF-8643 and 2x SFF-8644 interfaces for internal and external NVMe expansion.
Compliant with PCIe 3.0 specifications and backward compatible with PCIe 2.0.
Supports connection to external NVMe expansion cabinets and cluster devices via SFF-8644.
