Engineered to keep up to ten high-TDP GPUs utilized
Performance is a system design here — CPU, memory, retimer-free interconnect and cooling are balanced around the accelerators.
Xeon up to 385 W
Two 4th/5th-Generation processors supply high core counts and the PCIe 5.0 lanes for dense accelerator builds.
Up to 10 dual-width
A cascaded topology fits ten cards per node; the balanced topology gives eight GPUs a wide PCIe x32 path.
PCIe 5.0 & OCP 3.0
A retimer-free design lowers latency and power, while up to three OCP NICs carry high-speed cluster traffic.
Sustained cooling
6–8 custom counter-rotating fans and up to four Titanium PSUs keep high-TDP cards stable under full load.
Flagship acceleration in an air-cooled, serviceable 4U chassis
The X-lattice front bezel maximizes air intake while modular risers, switchable topology and drive cages keep the system field-serviceable.
Behind the X-lattice bezel, hot-swap drive cages feed a wall of 6 or 8 counter-rotating fans that push air across the dual-CPU motherboard and the rear accelerator risers. Software switches the internal topology between a single-root cascaded layout for up to ten dual-width cards and a double-root balanced layout that gives eight GPUs a wide PCIe x32 connection. A retimer-free chip design cuts lane latency and power, and up to three OCP 3.0 NICs mount on the board to save slots. Fans and PSUs are hot-swap and redundant, so a component failure does not take the GPU node down during production AI workloads.

Cluster deployment, power density and delivery
Rows of high-TDP GPU nodes require careful power and cooling planning; we support rack layout, circuit sizing and export logistics so the cluster is installable on arrival.
Rack and thermal planning
We confirm rack depth for the 898 mm chassis, supply guide rails and holding rails, and plan containment for 5–35°C operation. With 6–8 custom fans and front-to-back airflow, the nodes run in standard racks, and we advise on the number of nodes per rack for your ambient temperature.
High-density power sizing
Configurations up to four 3000 W Titanium PSUs demand matching rack power, PDU and circuit capacity. We calculate per-node and per-row power under simultaneous training load and specify the N+N/N+M PSU redundancy to match your availability needs.
Cluster networking and delivery
We help size the up-to-three OCP fabric for GPUDirect RDMA traffic, align firmware across the batch, and arrange export packaging and documents. A multi-node order can be pre-configured to one BIOS/BMC/RAID baseline and burn-in tested before shipment.
How to choose the right G5500 V7 configuration
Maximum accelerator count
Use the cascaded single-root topology when the goal is the most cards per node and the workload scales efficiently across ten GPUs.
Widest balanced path
Use the double-root balanced topology for eight GPUs on PCIe x32 when per-GPU host bandwidth matters most for training efficiency.
Inference and storage
Reduce GPU count, add NVMe and high-throughput OCP networking, and size the PSUs for the serving workload rather than peak training.
Every G5500 V7 is checked before it ships
Independent quality assurance signs the build only after every stage passes. The same checklist runs on every order whether it is one unit or a batch deployment, so the systems arriving in your data centre match the configuration and performance you were quoted.
Configuration verification
We check every CPU, GPU, memory module, drive, RAID controller and network adapter against the BOM and the agreed firmware levels before assembly.
Assembly and cable management
Components are seated and torqued to spec, power and signal cables routed for the front-to-back airflow path, and GPU retention and power cabling double-checked.
Full POST and firmware checks
The complete configuration boots through POST; CPU, memory and all accelerators are enumerated, and BIOS/BMC and RAID firmware versions are confirmed.
Extended burn-in under load
The server runs a high-utilization compute and GPU stress test to surface thermal, power or memory faults long before it reaches your rack.
Storage and RAID validation
RAID arrays are built and verified, hot-swap behaviour tested, and boot volumes confirmed independent of data drives.
Final independent QC sign-off
A second engineer reviews the test record and configuration, then signs off and seals the unit for export packaging and shipment.
Tested, documented, warranted. A test record accompanies every build and the 3-year warranty starts only after the unit passes final QC. Our team supports remote diagnosis and replacement parts through the warranty terms.
Backed by warranty, tested and export-ready

xFusion FusionServer G5500 V7 questions
What is the FusionServer G5500 V7?
It is xFusion’s flagship 4U accelerated computing server, with two 4th/5th-Generation Intel Xeon Scalable processors, 32 DDR5 DIMMs, PCIe 5.0 and up to 10 dual-width GPU accelerators, designed for large-model training, GPU clusters, cloud inference, HPC and VDI.
Does it support 8 or 10 dual-width GPUs?
Both. The cascaded single-root topology supports up to 10 dual-width cards for maximum accelerator count, while the double-root balanced topology runs 8 GPUs on a wide PCIe x32 CPU-to-GPU path. You select the topology for the workload and can switch it in software.
Which NVIDIA accelerators can I configure?
The platform supports high-TDP dual-width cards including NVIDIA H100/H200-class accelerators for training and dual-width inference cards for serving, with power options up to four 3000 W Titanium PSUs. We confirm card, riser and PSU compatibility before quoting.
What are the cascaded and balanced topologies?
Cascaded (single-root) fits up to 10 GPUs by extending one CPU root complex; balanced (double-root) splits eight GPUs across both CPUs on PCIe x32 for maximum per-GPU bandwidth. One-click software switchover adapts the node to training or serving.
Is it air-cooled or liquid-cooled?
It is air-cooled, with 6 or 8 hot-swap counter-rotating custom fans in N+1 redundancy and up to four Platinum/Titanium PSUs in N+N/N+M redundancy, so it deploys in a standard rack without liquid-cooling infrastructure.
How is the G5500 V7 different from the G5500 V6?
The V7 uses 4th/5th-Generation Xeon Scalable processors (up to 385 W), DDR5 and PCIe 5.0 with up to 10 dual-width GPUs. The V6 uses 3rd-Generation Xeon (Ice Lake), DDR4 and PCIe 4.0 with up to 8 dual-width cards. The V7 is the higher-bandwidth, newer platform.
How do nodes form a GPU cluster?
Up to three OCP 3.0 NICs carry high-speed cluster traffic, and GPUDirect Storage, RDMA and peer-to-peer let GPUs and nodes exchange data efficiently. We can size networking, power and rack layout for a multi-node deployment.
How do you test each G5500 V7 before shipment?
Every build goes through component verification, assembly and cable checks, full POST and firmware diagnostics, an extended high-utilization compute and GPU burn-in, storage and RAID validation, and a final independent QC sign-off. A test record accompanies the order and the 3-year warranty starts only after the unit passes, so no system ships untested.
What warranty, lead time and condition apply?
We supply the G5500 V7 as a brand-new server with a 3-year warranty, configured and burn-in tested before shipment. Quotations are normally provided within one working day and lead time depends on the CPU and GPU selected; export packaging and documentation are arranged for international orders.
