This chassis

The whole host, not a slice

The CPUs, system memory and local NVMe come with the GPUs. Nothing is carved up for other tenants.

FAQ

Before you rent it.

Short answers. The docs have the long ones.
Do I share the Supermicro SYS-822GS-NB3RT HGX with anyone?
No. You rent the whole machine: all eight B300 GPUs, the host and its system memory. Nobody else runs work on it while it is yours.
How is it billed?
Per second while it runs. On demand it is €48.00 per hour for the full server, or €40.00 per hour on a 12-month reservation. Invoices are in euros.
What does “Configurable on request” mean?
The builder's listing leaves that part open. We fit it to your order, for example CPU or local storage, before handover and confirm the exact configuration in writing.
Can I join it with other servers?
Yes. Instant Clusters link several 8-GPU servers over a high-speed fabric. Start on one node and add more when the job needs them.
Which regions can I deploy in?
Nexpod runs in EU-AMS-1, EU-FRA-1 and US-NYC-1. You pick the region at deploy time and the console shows current capacity for this model.
