What is a reserved GPU instance?
It is GPU capacity committed for a defined duration to secure availability and budget for inference, fine-tuning, LLMs, rendering or HPC compute.
GPU server or reserved instance: secure AI capacity before demand peaks
GPU server, reserved GPU instance and GPU rental searches express a capacity need: buyers want to know which hardware is available, how long they can reserve it and how they will access it.
VOLTANEUM connects GPU hosting, bare metal GPU servers, GPU Cloud, immersion colocation and monthly commitments to reduce uncertainty for AI, LLM, inference, fine-tuning, rendering and HPC workloads.
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
The GPU server reserved instance query often comes from a buyer who already has a workload: inference, fine-tuning, private LLM, rendering, simulation, scientific computing or machine learning pipeline. The page must therefore discuss availability, duration, access, drivers, OS, storage and networking.
A reserved instance only has value if the capacity is usable during the promised period. For GPUs, that means clarifying model, VRAM, isolation, bare metal or virtualized level, maintenance terms and delivery process.
VOLTANEUM benefits from connecting this intent to immersion cooling: as GPU density increases, cooling, power, noise, remote management access and DCIM visibility become decisive.
VOLTANEUM offers and capacity
- Detailed offers should specify capacity, reserved power, cooling, metered electricity, setup, stock conditions and immersion-ready validation.
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
What is the difference between GPU Cloud and bare metal GPU server?
GPU Cloud exposes GPU capacity as a service, while a bare metal GPU server reserves a physical node for the customer with more control over OS, drivers and operations.
Why reserve instead of paying only on demand?
Reservation becomes useful when the workload is regular, GPU availability is critical or the company wants to stabilize monthly cost.
What should be checked before ordering?
GPU model, VRAM, CPU, RAM, NVMe storage, network, OS, drivers, access, commitment duration, lead time, support, backup and cancellation terms.
