PCIe 5.0 x16 to 4-Port Built-in MCIO 8I NVMe Switching Adapter Supports 3 Split Modes: 2 * X16, 4 * X8, and 8 * X4. Integrated NVMe hot swappable Function

Product Overview 89048-4I is a PCIe5.0 x16 to 4-port built-in MCIO 8I NVMe switch adapter developed based on Broadcom PEX89048. It supports three flexible splitting configurations: 2x16,4x8, and 8x4, allowing users to configure flexibly according to their actual needs. Whether it's high-bandwidth single-device access or multi-device parallel processing, it can handle them effortlessly. It can directly support up to 8 M.2, U.2/U.3 or E3.S SSDs. The fan features a temperature-controlled startup design, automatically turning on only when the network card temperature exceeds the set threshold, reducing power consumption while effectively controlling energy usage. The 89048-4I is engineered for high-end applications like SSD performance testing and GPU expansion testing. Its PCIe 5.0 connection delivers high bandwidth and low latency, ensuring accurate and real-time test data while streamlining product development and verification workflows

• ***The default shipping mode is 8 * x4. If you need other modes, please contact the seller before purchasing.*** Model ：HR89048-4I(X4) controller： Broadcom PEX89048 PCIe highway ：PCIe5.0(32 GT/s) x16 Height of baffle pl ate：Half-height and full-height confi gurations Junctor ：MCIO 8I Compatible hard drive types ：U.2,U.3,E3.S (connected by wire) SSD hot plug ：Yes Split method： 2*X16,4*X8,8*X4
• Default 8 * X4 requires other modes. Please contact the seller to set them before shipping. The configurable number of downstream PCIe channels, through customizable firmware, allows for flexible allocation of downstream bandwidth to meet different storage requirements: 8 * x4 mode: Each port has x4 channels and supports up to 8 NVMe SSDs, maximizing individual device performance. 4 * x8 mode: Each port has X8 channels and supports up to 4 PCIEs in X8 mode, which can expand up to 4 GPUs. 2 * x16 mode: Create two independent x16 channel logical paths for each port (mainly used for PCIE channel extension linking GPU or other PCIE devices)
