Topstar Technology team at the 27th China International Optoelectronic Exposition (CIOE 2026), Shenzhen Introduction: When AI Meets光速 At the 27th China International Optoelectronic Exposition (CIOE 2026) held in Shenzhen this September, one message resonated across every exhibition hall: the AI revo...

China's DRAM industry reached an important milestone in July 2026 when ChangXin Memory Technologies (CXMT) began trading on the Shanghai Stock Exchange STAR Market under stock code 688825. For the server hardware market, however, the bigger story is not the IPO itself. It is CXMT's progress in DDR5 ...

For global data-center hardware procurement, the supplier’s location can affect documentation, routing options, communication, and the way a buyer structures a purchase order. It should not replace technical qualification, export-control review, or a clear commercial agreement. This guide explains h...

Enterprise SSD selection for an AI server is not a contest between form-factor names. U.2, U.3, E1.S, and other EDSFF options describe a physical and electrical ecosystem that must match the server chassis, backplane, controller, carrier, cooling design, and service model. A drive that is fast on pa...

Choosing server memory for an AI or data-center deployment requires more than selecting the largest DDR5 capacity that is available. RDIMM and LRDIMM modules have different electrical designs, platform-support requirements, and deployment goals. The correct choice depends on the server generation, C...

Choosing between NVIDIA ConnectX-7 and ConnectX-6 Dx for an AI server is a design decision, not a generational upgrade exercise. Both adapter families can support modern Ethernet and RDMA-oriented workloads, but the correct choice depends on the fabric you are building, the exact adapter SKU, the se...

Selecting optical modules for an NVIDIA Spectrum switch is an end-to-end compatibility task. A transceiver is not chosen only by the number printed on the front label. The switch model, port cage, firmware, port speed and breakout mode, adapter or remote switch, fibre type, connector, reach, and pow...

The choice between 800G and 400G optical transceivers is not simply a question of buying the faster module. AI-cluster networking must balance GPU density, fabric topology, switch-port availability, cabling reach, optics power, host-adapter capability, resiliency, and the time horizon of the deploym...

Official confirmation from China’s Ministry of Foreign Affairs on July 13 marks a landmark milestone for the 9th World Artificial Intelligence Conference (WAIC 2026), set to launch from July 17 to 20 at Shanghai Expo, Zhangjiang and West Bund venues. A top national leader will deliver a keynote addr...

Server-memory procurement often starts with a part number, but a part number should be treated as the beginning of verification rather than the end of it. The Samsung M321R8GA0PB0-CWMXJ description used in a quotation, inventory list, or request for proposal should be checked carefully against the m...

H200 procurement begins with the exact system, not a market headline NVIDIA H200 is a GPU family used in multiple server and system configurations. It should not be selected from news about market availability, trade policy, regional supply, or generic “clearance” claims. Those subjects change quick...

QM9790 is an externally managed Quantum-2 NDR InfiniBand switch NVIDIA QM9790 is a fixed-configuration NDR InfiniBand switch for high-performance computing and AI fabric deployments. It should be selected from its documented system characteristics, not from market forecasts, price speculation, or ge...
