Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The PM42068B1-FEI is a programmable, highly reliable switch that supports shared pooling of high-performance PCIe connections to Gpus, NVMe, SSDS, and other endpoints, and multi-host sharing of single root Input/Output Virtualization (SR-IOV) endpoints.

This switch belongs to the Switchtec Gen 4 PAX series and supports 68 channels, 36 ports and hot-swappable controllers for each port. The PM42068B1-FEI switch features advanced error control, comprehensive diagnostic and debugging capabilities, a wide range of I/O interfaces, and an integrated MIPS processor.

Performance

It is connected to high-performance PCIe architectures with Gpus, NVMe SSDS, and other endpoint pools, overcoming the limitations of rack-level multi-host systems based on PCIe tree topologies

High-reliability PCIe, featuring powerful error control, hot-swappable and accidental swappable controllers for each port, end-to-end data integrity protection, and high-quality, low-power SerDes

SR-IOV and multi-host sharing of multi-functional endpoints

Supporting up to 36 ports and flexible ×1, ×2, ×4, ×8 and ×16 port forks, it can significantly save power consumption, cost and circuit board space, with no restrictions on configuring ports as upstream or downstream

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
