CUSTOM BUILD · GPU SERVERS

GPU servers tuned for your model.

Training, fine-tuning, inference — each has a different optimal hardware shape. We spec, integrate, and validate GPU servers around your specific workload, then ship them ready to join your fabric. From single-node inference boxes to multi-rack training clusters.

WHY US

Three things that separate us from a reseller.

Anyone can quote you an HGX 8-GPU box. Knowing whether you actually need NVLink fabric, what the right CPU-to-GPU ratio is, and how to debug an InfiniBand link that drops at 2 AM — that's the work.

▸ 01 / EXPERIENCE
GPU workloads in production
Live inference clusters, multi-node training jobs, research compute. We've seen what fails when the model is mid-epoch and the cluster is loaded.
▸ 02 / DEBUG
Hardware + software debug capability
PCIe topology issues, NVLink link-down events, NCCL collective stalls, driver and CUDA version conflicts — we troubleshoot end-to-end instead of bouncing tickets between vendors.
▸ 03 / HA DESIGN
High-availability for GPU fabric
Redundant InfiniBand / RoCE planes, dual-PSU, BMC out-of-band, NCCL-aware topology, checkpoint-friendly storage paths. Designed so a single node failure doesn't kill the run.
WHAT WE BUILD

GPU configurations we have shipped.

From single-card inference nodes to multi-node training clusters with NVLink and InfiniBand fabric. Each baseline has been validated in production.

▸ INFERENCE NODES
L40S / H100 PCIe single & dual-GPU
High clock CPU, large memory, NVMe staging. Tuned for low-latency inference serving, RAG pipelines, and CPU-side preprocessing throughput.
▸ TRAINING NODES (8-GPU)
HGX H100 / H200 8-GPU servers
SXM5 with NVLink fabric, dual-socket EPYC or Xeon, 8× ConnectX-7 400G NICs for InfiniBand. Validated for multi-node NCCL throughput.
▸ NVL72 / GB200
NVIDIA Blackwell rack-scale
Full NVL72 deployments with in-rack CDU, Quantum-X800 leaf/spine, integrated with our liquid-cooled Container DC or your facility.
▸ MULTI-NODE FABRIC
InfiniBand / RoCE training clusters
Cluster-level design: rail-optimized topology, congestion control tuning, GPUDirect RDMA validation, NCCL test sweeps before handover.
SHIPPED PROJECTS

What we've put into production.

Two recent GPU deployments — one for inference at scale, one supporting an active research portfolio.

▸ CASE STUDY · 39AI · INFERENCE CLUSTER

Production inference cluster, paired with a 100G fabric upgrade.

39ai needed an inference cluster sized for sustained production traffic, then needed it to actually use that capacity once the storage tier could keep up. We delivered both halves.

Scope: GPU server spec'd for inference latency targets, integrated with the existing data plane, then a follow-on network upgrade taking the inter-rack fabric from 25G to 100G — the same fabric upgrade that unlocked storage throughput also unlocked sustained GPU utilization.

▸ CASE STUDY · SHENZHEN LINGXINGYU TECHNOLOGY

GPU cluster supporting multiple research projects in parallel.

Lingxingyu runs multiple active research initiatives that share a common GPU pool. The cluster needs to handle bursty multi-tenant scheduling without resource contention killing job throughput.

Scope: GPU server fleet integrated with a paired storage tier and unified network fabric, BMC standardized for fleet management, partitioning and scheduler integration validated with real research workloads before handover.
