AI server chassis, 8-accelerator, air-cooled
AI服务器（8卡，风冷） · IT hardware
Export status depends on what is installed. The bare chassis is broadly exportable; populated with US-origin accelerators it is caught by 3A090/4A090 and is not re-exportable from China. Classify the actual configuration, and treat a buyer who intends to fit controlled parts as a KYC red flag (Supp. 3 to Part 732).
What Qing asks
One dense message. Five is the whole budget per supplier reply, so the questions that decide comparability go first.
- 1.
加速平台是HGX SXM基板、OAM UBB基板，还是标准PCIe插卡方案？
Is the accelerator subsystem an HGX SXM baseboard, an OAM UBB, or standard PCIe add-in cards?
Determines chassis, power, cooling, price band and export-control treatment simultaneously.
- 2.
每台配几张加速卡？具体型号是什么？单卡TDP多少瓦？
How many accelerators per system, exactly which model, and what is the per-module TDP?
The specific model is what triggers or clears 3A090/4A090 - a generic 'GPU server' quote is unusable.
- 3.
加速卡是贵方供货，还是我方自备、贵方只提供不含卡的平台(机头+机箱+电源+散热)？两种报价都请给出。
Do you supply the accelerators, or do you quote the GPU-less platform (head node, chassis, power, thermal) with buyer-supplied cards? Please price both.
The GPU-less platform is usually EAR99 and is the compliant sourcing path; force both quotes.
- 4.
请以书面形式给出实际发货配置的ECCN分类(例如EAR99 / 3A090 / 4A090 / 4A090.z)，以及原产地判定依据。
Provide in writing the ECCN of the exact shipped configuration (EAR99 / 3A090 / 4A090 / 4A090.z) and the country-of-origin determination.
Classification follows the configuration as shipped, not the model family; get it in writing per SKU.
- 5.
整机峰值功耗多少千瓦？配几颗多少瓦的电源、什么冗余方式？输入是220V单相、三相还是48V直流？
Peak system power in kW, PSU count/wattage/redundancy, and input type (single-phase, three-phase, or 48V DC)?
An 8-GPU node can pull 8-10 kW; it changes the rack PDU, busbar and often the whole room plan.
- 6.
散热方式是风冷、冷板液冷还是浸没式？若为冷板液冷，快接头是UQD还是自有标准？进水温度、流量和压降要求各是多少？残余风冷占比多少？
Air, cold-plate liquid, or immersion? If liquid: UQD or proprietary couplings, required inlet temperature, flow rate, pressure drop, and residual air-cooled fraction?
Coupling mismatch between sled and manifold is the most common liquid-cooling integration failure.
- 7.
整机高度几U？净深度多少毫米？满配重量多少公斤？建议的最小机柜深度是1000mm还是1200mm？
Chassis height in U, net depth in mm, fully-configured weight in kg, and minimum recommended rack depth (1000 mm or 1200 mm)?
8U HGX-class nodes run near 900 mm deep and 130 kg; 1200 mm racks are the working assumption.
- 8.
给显卡供电用的是12V-2x6(12VHPWR)还是8pin接口？每张卡配几根线？机箱内线缆长度够不够接到最上面那张卡？总的显卡供电冗余是多少瓦？
Is GPU power delivered over 12V-2x6/12VHPWR or 8-pin connectors, how many cables per card, are the internal cables long enough to reach the topmost card, and what is the total GPU power budget?
A recurring integration blocker on PCIe GPU builds: right chassis, right PSU, wrong or too-short power cables.
- 9.
这块UBB基板具体支持哪几家的OAM模块？OAM是v1.1还是v1.5？单模块最大供电多少瓦？换成别家的OAM模块需不需要换基板或改固件？
Which vendors' OAM modules does this UBB support, is it OAM v1.1 or v1.5, what is the per-module power ceiling, and does switching accelerator vendor require a different baseboard or firmware?
'OAM' implies interchangeability that does not exist in practice. This decides whether the GPU-less purchase strategy actually preserves optionality.
- 10.
冷板液冷能带走整机多少百分比的热量？剩下多少还得靠风冷？CPU和GPU都上冷板了吗，内存和电源呢？进水温度、流量和压降要求各是多少？
What percentage of system heat does the cold-plate loop remove, how much remains air-cooled, are CPU and GPU both cold-plated (and memory, PSU?), and what inlet temperature, flow rate and pressure drop are required?
Rephrased from the report's '残余风冷占比', which a factory rep will not recognise. This number sizes the room air-handling you still have to buy.
- 11.
整机柜是整柜带设备发运，还是空柜发运、到现场再装机？如果整柜发运，柜体的动态运输承重是多少公斤？用什么减震包装？总毛重多少？
Is the rack shipped populated or empty for field integration? If populated, what is the rack's dynamic (in-transit) load rating in kg, what shock packaging is used, and what is total gross weight?
Static and dynamic rack ratings differ greatly. A populated rack shipped on a static rating arrives with bent posts and no insurance claim.
- 12.
PCIe拓扑是单root还是双root？用的是哪款PCIe Switch芯片？GPU与网卡的绑定关系(每卡对应几张网卡)是怎样的？
Single-root or dual-root PCIe topology, which PCIe switch part, and what is the GPU-to-NIC affinity ratio?
- 13.
后部可装几张横向扩展网卡？是OCP NIC 3.0还是标准PCIe？端口是QSFP112还是OSFP？带外管理口独立吗？
How many scale-out NIC slots at the rear, OCP NIC 3.0 or standard PCIe, port type (QSFP112/OSFP), and is there a dedicated OOB management port?
- 14.
在35摄氏度进风条件下，本机箱单卡可持续支持的最大TDP是多少瓦？是否有实测热测试报告？
At 35C inlet, what sustained per-accelerator TDP does this chassis support, and is there a measured thermal test report?
这批货是全新原封、官翻、拆机件还是工程样片(ES/QS)？请在形式发票上写明状态。如果是拆机件，来源和使用时长是多少？
报价是EXW、FOB还是CIF？指定口岸是哪里？报价里不含哪些费用(出口报关、内陆运输、保险、目的港费用)？
外箱尺寸多少？每箱装几台、毛重多少公斤？每托盘几箱？整单总体积多少立方米？是木托还是纸托、是否需要熏蒸证明？
请给出阶梯报价：1台、10台、50台、100台各是什么价格？每个型号的起订量是多少？价格有效期多久？
出口报关准备用哪个HS编码？报价是含税价还是不含税价？该编码的出口退税率是多少、退税是否已经体现在报价里？
整机原产地写哪里？能否出具原产地证(一般CO还是Form E/RCEP优惠证)？货物是从中国直接出口，还是经香港、新加坡或越南转运？
质保多少个月？DOA(到货即损)申报期限是几天？返修是寄回中国还是有海外备件？是否提供先行换货？返修运费谁承担？
这个托架/导轨/面板是原厂件还是兼容件？上面有没有原厂LOGO或型号标识？能否书面保证不侵犯第三方商标和专利，并承担相关责任？
整机和关键部件(CPU、加速卡、网卡)的原产地分别是哪里？产品里有没有使用美国原产的芯片、软件或技术？大概占多少比例？能不能配合签署最终用户和最终用途声明、承诺不转运？这个型号以前出口过哪些国家？
合同和发票的签约主体全称是什么？统一社会信用代码是多少？工厂是自有还是代工？母公司或控股股东是谁、持股比例多少？有没有国资或上市公司背景？
请提供公司全称、统一社会信用代码和营业执照复印件。贵司是生产工厂、原厂授权代理还是贸易商？如为工厂，工厂地址在哪里、可否安排验厂或视频验厂？开票主体与收款主体是否为同一家公司？
最小起订量是多少？请给出阶梯报价（如100/500/1000/5000片）。报价有效期多少天？NAND和HDD价格波动时如何调价？是否接受锁价？

How buyers get burned here
Category-specific, from research rather than generic advice
- The 'manufacturer' that is a trading company. On Alibaba and Made-in-China this is the default state for racks, containment, rack PDUs, cabling and small cooling accessories. The distinguishing evidence: (a) 经营范围 in the business licence says 销售/贸易 but not 生产; (b) the 'factory address' equals the registered office and is in an office tower, not an industrial park; (c) no 生产许可 or product certification is held in the seller's own name — certificates show a different company; (d) they are not in any CIOE/China Refrigeration/CDCC exhibitor list; (e) they quote across five unrelated categories. Always cross-check the 统一社会信用代码 on gsxt.gov.cn.
- The reverse trap: assuming a trader is always bad. For a 20-line mixed BOM, a competent Guangdong trading company is often the only party that will handle consolidation, export documentation and one invoice. The trap is paying manufacturer margins for trader service, or letting the trader hide who actually made the goods so warranty has no counterparty.
- Cooling capacity quoted at undeclared conditions. A '100 kW' CRAH at 15/21C chilled water is a different machine from a '100 kW' CRAH at 12/18C, and a '35 kW' passive rear door at 12C water is not the same product as one at 18C. Chinese quotes routinely omit the conditions and Western buyers routinely compare the headline number.
- CDU kW ratings with only one loop temperature. A CDU is defined by primary in, primary out, secondary in, secondary out and both flow rates. A single number is not a specification and cannot be compared across vendors.
- Residual air heat in liquid-cooled racks. Vendors state '90% heat captured to liquid' and buyers size the room for 10%. In practice the uncaptured fraction is often 15-25% under real workloads, and a 120 kW rack then dumps 25 kW into a hall designed for 12. Ask for kW of residual air heat per chassis, in writing.
- Filled floor loading for immersion tanks. A filled immersion tank can exceed 2,000 kg/m2. Chinese quotes give the dry weight. The building, not the tank, is what fails.
- Aluminium substituted for copper in busbar, busway and switchgear. It is legal, it meets the current rating, and it is not what the buyer priced. Specify conductor material and cross-section, and weigh a sample on arrival.
