InfiniBand, Spectrum-X, and the rack-to-rack plumbing for AI clusters.

// QUICK ANSWER

Group APZ supplies the networking and rack infrastructure that makes a GPU cluster usable: NVIDIA Quantum InfiniBand, Spectrum-X Ethernet, BlueField DPUs, optical cabling, PDUs, racks, and structured cabling, all coordinated against the compute build schedule.

// 01Approach

How we approach networking

The fastest GPUs are wasted without a non-blocking fabric and a clean cabling plan. We source and stage the entire data-plane and management-plane stack — switches, transceivers, optical cable, DACs, PDUs, racks, KVM, and out-of-band — so the cluster comes up on day one instead of week six.

// 02Outcomes

01Validated fabric topology (rail-optimized, fat-tree, or dragonfly) before order
02Bill of materials covering every optic, cable length, and spare
03Consolidated delivery aligned to cabling and commissioning crews
04Reduced cost-per-port through volume negotiation and SKU rationalization

// 03Deliverables

01Topology and BOM review with the integrator or in-house network team
02RFQ across NVIDIA, Arista, Cisco, and optics partners
03Cable schedules and labeling plans matched to the rack elevation
04Logistics: staging, kitting, and just-in-time delivery to the data hall
// 04Questions

Yes. Group APZ supplies NVIDIA Quantum InfiniBand and Spectrum-X Ethernet fabrics, including switches, BlueField DPUs, HCAs, and the full optics and cabling BOM, sized and staged against the compute delivery schedule.
