Kentino AI Node V100 — 8× NVIDIA V100 SXM2, ex-datacentre

An eight-GPU Volta node sourced from the ex-datacentre market and refurbished by us: eight V100 SXM2 modules on an NVLink baseboard, 256 GB of HBM2 at 900 GB/s per GPU, 300 GB/s GPU-to-GPU. This is deliberately a budget machine. It is the cheapest way we know to get real NVLink-connected multi-GPU with 7.8 TFLOPS of FP64 per GPU into a lab, and for FP64 HPC and validated fp16 training codes it is still a perfectly good tool. For modern LLM serving it is not - see below, we are specific about why.

Hardware

What it runs

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

Throughput figures are estimates derived from published vendor specifications and community benchmarks for this GPU generation, not measurements taken on this exact configuration. We will give you measured numbers for your model and context length before you commit.

Power and cooling

Roughly 3.2 kW sustained: 2.4 kW of GPU plus host. Lowest wall draw of our node range in absolute terms, but by far the worst performance per watt - around an eighth of an H100 node's fp16 throughput for a bit over half the power. Volta SXM2 was built for datacentre-grade front-to-back airflow and is unforgiving in a poorly ventilated rack.

Be clear about what this is

No bf16, no fp8, no INT8 tensor cores. Volta has none of them. Most 2026 quantised inference stacks assume bf16 or better, so a large part of the current ecosystem either will not run or will run badly. Treat this as fp16 training and FP64 HPC hardware, not an LLM serving node.

No NVSwitch. NVLink 2 is a hybrid-cube mesh, not full any-to-any. Eight-way tensor parallelism is measurably worse here than on the A100, H100 and H200 nodes.

Availability is not guaranteed. There is no new-channel supply for this hardware. Every unit is individually sourced from the secondary market, so we quote on confirmed availability only and cannot promise a date before we have a unit identified.

Refurbished, not new. This is six to eight year old hardware. Warranty is Kentino refurb terms, not manufacturer channel warranty. Degraded thermal pads are the main failure mode on these modules and every unit we ship has had them replaced.

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 the thing blocking you, this is the node that does not need it.

What you get from Kentino

Kentino sources, refurbishes and supports this node: thermal pad and paste renewal, fan replacement, 72 hour 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 our refurb warranty.

We run the same refurbishment process on ex-mining accelerator hardware, so this is an established bench workflow rather than a one-off.

Price shown is EUR excluding VAT, EXW Prague (Incoterms 2020). Collection, freight, insurance and any destination import duties are for the buyer’s account. Lead time on request.

Priced per sourced unit — these come from the secondary market, so availability drives the date. Tell us what you need it for - if your workload is modern LLM inference we will point you at the A100 node instead, which is better value than this once you account for what Volta cannot do.
