Kentino AI Node V100 HGX-2 — 16× NVIDIA V100 SXM3 32 GB, 512 GB HBM2

A 10U node carrying sixteen NVIDIA V100 SXM3 modules on an HGX-2 baseboard with full NVSwitch any-to-any connectivity: 512 GB of HBM2, 124.8 TFLOPS of FP64, and every GPU talking to every other at full bandwidth. We build these to order on a Supermicro SYS-9029GP-TNVRT host. It is the cheapest route we know to a half-terabyte NVSwitch-pooled VRAM space, and for double-precision HPC it remains a serious tool.

Hardware

What it runs

Volta is fp16 and FP64 hardware. These are the workloads it is genuinely good at.

Throughput figures are published vendor specifications for this GPU generation, not measurements on this exact configuration. We will give you measured numbers for your workload before you commit.

Power and cooling

Sixteen modules at 350 W is 5.6 kW of GPU - the same wall draw as an eight-GPU Hopper node, for a fraction of the throughput. Budget a dedicated 32 A three-phase feed and roughly one node per 10 kW of rack. The 10U chassis also takes a quarter of a standard rack. It needs genuine datacentre front-to-back airflow and a contained cold aisle below 24 C for 24/7 operation.

Be clear about what this is

No bf16, no fp8, no INT8 tensor cores. Volta has none of them. Most current quantised inference stacks assume bf16 or better, so a large part of today's ecosystem either will not run or will run badly here. 512 GB sounds competitive against a newer node, but the pool is HBM2 at 900 GB/s with fp16-only tensor paths. Do not buy this as an LLM serving node on the capacity number alone - if that is your workload, ask us about the A100 node instead.

Built from sourced baseboards. There is no new-channel supply of HGX-2 baseboards. We source them, and if they are ex-datacentre every module gets fresh thermal pads and paste plus a 72 hour burn-in before it ships - degraded factory pads are the main failure mode on hardware of this age. Lead time depends on sourcing and we will give you a real date, not an optimistic one.

One genuine advantage: V100 predates the Advanced Computing Item thresholds, so there is no KYC form and no End User Certificate. If export paperwork is what is blocking you on newer hardware, this is the node that does not need it.

What you get from Kentino

We build, test and support the complete node: host selection, assembly, thermal work on the baseboard, burn-in with a written report, OS and driver stack pinned to a Volta-compatible CUDA version, rack and airflow guidance, EU-based logistics and warranty.

Priced on request. Tell us your workload and we will come back with a firm quote, a realistic lead time, and an honest view of whether this or a newer node is the better buy.
