PEX 8724 PCI Express 3.0 M.2 KEY M NVMe Extend Card

Users to connect multiple hosts to their respective endpoints via scalable, high bandwidth, non-blocking 

interconnection to a wide variety of applications including servers, storage, communications, and graphics platforms. 


The PEX 8724 PCI Express 3.0 to M.2 KEY M NVMe card, without power supply. Can be directly converted to NVMe M.2 SSD, BIOS supports PCLs slot bifurcation. Comes with pcie splitting protocol-PEX8724 chip, it can be easily expanded without motherboard support splitting. The PEX 8724 is well suited for fan-out, aggregation, and peer-to-peer traffic patterns. Each M.2 SSD channel has its own PCIe 3.0 x4 (32Gb/s) bandwidth, and its transmission performance is 20 times faster than SATA, Better improve the speed of NVMe reuse, making your storage solution more convenient and efficient. 

Key Features

Reliability, Availability, Serviceability

    - PCI Express 3.0 x8 bandwidth

    - 4-Port M.2 NVMe (providing dedicated PCIe 3.0 X4 bandwidth for each interface) channels; 

      BIOS supports PCLs slot bifurcation 

    - Built-in fan and heat sink cooling treatment

    - Adopt Broadcom's high-performance PEX 8724 chip

    - Provide NVMe SSD high-performance storage solutions

    - There are no compatibility requirements such as operating system, motherboard model, etc. 

       and it can be easily expanded as long as the motherboard has a pcie slot.

Standards Compliant

    - PCI Express Base Specification, r3.0 (Backwards compatible with PCIe 2.0, PCIe 1.0 and PCIe 1.0a)

    - PCI Power Management Spec, r1.2

    - Supports Access Control Services

    - Dynamic link-width control

    - Dynamic SerDes speed control

Multi-Host Architecture

Configurable Non-Transparent (NT) port

    - Failover with NT port

    - Up to 4 upstream/Host ports with 1+1 or N+1 failover to other upstream ports

No driver is required because the driver is transparent to the operating system
