Frequently Asked Questions
Q1: What is main function of PEX8796‑AB80BIG?
A: Industrial‑grade 96‑lane 24‑port PCIe Gen3 switch with Multi‑Root for multi‑host CPU, GPU and NVMe interconnection.
Q2: What is difference between Multi‑Root and NTB?
A: Multi‑Root allows multiple hosts to share ports directly. NTB supports conflict‑free data transfer for isolated host domains.
Q3: Is it backward compatible with PCIe Gen2 / Gen1?
A: Yes, auto‑negotiate speed and lane width, fully compatible with PCIe Gen2 & Gen1 devices.
Q4: What are similar Broadcom alternative parts?
A: PEX8794 (48‑lane lower spec), PEX8797 (higher‑end). No pin‑to‑pin replacement, hardware modification required.
Q5: How does it compare with competing PCIe Gen3 switches?
A: It has mature Multi‑Root & NTB firmware, widely used on enterprise servers. Competitors vary in lane count and power consumption.
Q6: How to get datasheet and bulk quotation?
A: Submit your requirement via inquiry form, we will send datasheet, stock status and price within 24 hours.
Q7: Notice for MSL Level‑4 moisture‑sensitive device?
A: MSL‑4 component. Complete reflow soldering within 72‑hours once moisture‑proof bag opened.
Q8: Can I change port lane count freely in hardware design?
A: Lane / port combination is configurable by firmware, follow official design reference for multi‑root layout.
