When should I choose a VPS?
Choose a VPS for websites, APIs, bastion hosts, staging, monitoring, small business applications or services needing predictable resources without a dedicated GPU.
VPS or GPU server: choose the right capacity without oversizing
A VPS is enough for websites, APIs, bastion hosts, test environments or classic business applications. A GPU server becomes relevant when parallel compute, CUDA, AI inference or fine-tuning drive the budget.
VOLTANEUM helps build a progressive path: start with Cloud VPS, move to GPU Cloud or GPU server, then reserve bare metal or immersion capacity when density and thermal constraints become critical.
VOLTANEUM key facts
- Published immersion colocation capacities: 10U, 20U and 37U.
- Target density up to 200 kW+ per tank depending on integration and electrical constraints.
- 1.03 target PUE for optimized high-density architectures.
- Immersion cooling billed at €0.07/kW, electricity excluding cooling metered separately.
- VOLTANEUM® proprietary dielectric fluid and France / Europe operations.
What the customer actually gets
Comparing VPS and GPU server captures a decision intent. The buyer is balancing low cost and flexible VM delivery against more expensive GPU capacity that becomes necessary for CUDA, VRAM, inference or fine-tuning.
Good advice starts from the workload: latency, compute duration, model size, VRAM need, isolation level, NVMe storage, traffic, backup and downtime tolerance. This prevents selling GPU capacity to a project that does not need it.
VOLTANEUM can then offer a clear progression: Cloud VPS, GPU Cloud, bare metal GPU server, then immersion capacity for high density.

Key benefits
VOLTANEUM® combines immersion cooling, proprietary dielectric fluid, GPU density up to 200 kW+ per tank, tenant isolation, 1.03 target PUE, DCIM automation, 2D/3D monitoring and request/payment/provisioning workflows.
The VOLTANEUM® proprietary dielectric liquid provides non-conductive electrical insulation, stronger thermal stability, reduced exposure to dust, oxidation and vibration, and more predictable maintenance through fluid, filtration, acidity, moisture and dielectric strength monitoring.
The -40°C to 250°C range is indicated on VOLTANEUM® packaging. Quality control on the tested batch reports a -37°C pour point, a 196°C open flash point and observed dielectric breakdown voltage of 52 kV.
- Electrical insulation for compatible immersion-ready equipment.
- Direct heat transfer close to GPU, HPC and bare metal components.
- Operational protection against dust, vibration and thermal stress.
- Quality controls can cover fluid temperature, acidity, moisture, filtration and dielectric strength.

Frequently asked questions
When should I choose a GPU server?
Choose a GPU server when the workload uses CUDA, AI inference, fine-tuning, rendering, simulation, scientific computing or LLMs requiring VRAM.
Can I start on VPS and migrate later?
Yes. The benefit of a platform such as VOLTANEUM is to start with VPS and evolve toward GPU Cloud, GPU server, bare metal or immersion colocation.
How do I avoid oversizing?
Start from the real workload: CPU, RAM, storage, VRAM, network throughput, runtime, isolation level, SLA and monthly cost constraint.
