What Is the Multi-GPU Servers?
A multi-GPU server places four or eight accelerators in one chassis and connects them with either an NVLink/NVSwitch fabric or PCIe Gen5. The interconnect choice, not the GPU count, usually determines how well a workload scales across those GPUs.
Doubling GPUs rarely doubles throughput. On distributed training, collective operations dominate scaling behaviour, so an eight-GPU node on an NVSwitch fabric with 900 GB/s of GPU-to-GPU bandwidth behaves very differently from eight PCIe cards sharing host bandwidth.
That is the central design decision we work through with buyers. Training workloads and large-model inference generally justify SXM baseboards with NVLink. Embarrassingly parallel inference, batch rendering and many fine-tuning jobs run perfectly well on PCIe topologies at meaningfully lower cost.
Beyond the node, the cluster fabric matters just as much: NIC-to-GPU affinity, rail-optimised topologies and 200–400G per node keep multi-node runs from stalling on communication.

Density, Airflow & Liquid Cooling for Dense Nodes
Eight-GPU nodes concentrate 6–12 kW into a few rack units. Even two such nodes exceed the design density of many older colocation halls, so power per rack and heat rejection capacity should be confirmed before hardware is ordered.
Air-cooled dense nodes need strict containment, blanking panels, controlled inlet temperature and enough CFM at high static pressure. Any recirculation between hot and cold aisles shows up quickly as throttled clocks.
Direct-to-chip liquid cooling raises achievable rack density substantially and reduces fan power, at the cost of manifolds, CDUs and leak detection. For greenfield AI halls it is increasingly the default rather than the exception.
Why Consider the Multi-GPU Servers?

Frequently Asked Questions
Is an 8-GPU node twice as fast as a 4-GPU node?
Rarely. Scaling depends on the interconnect and the workload's communication pattern. NVLink fabrics scale far better than PCIe for collective-heavy training.
When should I choose NVLink over PCIe?
Choose NVLink for distributed training and very large models. PCIe is usually sufficient and cheaper for independent inference workloads.
How much power does an 8-GPU node draw?
Typically 8–12 kW depending on GPU model and CPU configuration.
What network speed do these nodes need?
200G to 400G per node is common for multi-node training; inference clusters often run comfortably at lower speeds.
Can you deliver nodes pre-clustered?
Yes — see our AI cluster configurations for fabric, storage and staged multi-rack delivery.
