Selected sheets from the GPU Hall Network Reference Design — PE-P2 (75 pages, 1.6 MB), published as zoomable vector drawings with device-by-device explanations. More sheets are added continuously; the full PDF set is always complete.

  1. N-002-ENSheet N-002-EN: Hall key plan of 15 compute units and 10 central cabinetsThe hall's 15 compute units and 10 central cabinets are indexed on one 1:200 plan, and fan-wall names appear only where the index prints them.
  2. N-101-ENSheet N-101-EN: Dual-plane rail fabric from the tray NIC to the spine at 1.0:1One drawing carries both compute planes: 120 leaves and 54 spines per plane at 1.0:1, the per-unit link figures, and the shared OSFP cage, where a NIC or cage failure affects both planes for that NIC.
  3. N-111-ENSheet N-111-EN: Two BlueField-3 ports, one to each side's leaf; unused CVS ports reach the border panelEach tray BlueField-3 puts one 400G port on an A-side NS leaf and one on a B-side NS leaf, each side having 30 leaves (LG01 through LG30) at 54 / 28 down/up (1.929:1) and 7 CVS, and unused CVS ports reach EXT-IF-NS-A and EXT-IF-NS-B via the border panel, beyond which note 1 assumes no upstream equipment.
  4. N-121-ENSheet N-121-EN: How the SN2201 management switches reach SN4600C aggregation and EXT-IF-OOBOEM SN2201 switches in each GPU cabinet, and one SN2201 in each network cabinet, connect to SN4600C aggregation on sides A and B, with the per-strand pin map marked HOLD and addressing, upstream management and security zoning beyond EXT-IF-OOB left to the deploying organisation.
  5. N-201-ENSheet N-201-EN: Network-cabinet coordinates and fan-wall front zones on X 0–36 mThe X 0–36 m plan prints an X range and a front clearance for every network cabinet from NETA-CU01 to NETA-CU06, including the shared 1,050 mm zone where FW-01 and FW-02 face the row.
  6. N-202-ENSheet N-202-EN: Central OOB, CVS and spine cabinets and fan-wall fronts on X 35–72 mThe X 35–72 m plan draws the central OOB, CVS and spine cabinets in the row with the unit cabinets, and the table prints which of them face a fan wall at 1,050 mm and which keep a 2450 cold aisle.
  7. N-203-ENSheet N-203-EN: Network-cabinet coordinates and the FW-08 and FW-09 front zones on X 71–107 mThe X 71–107 m plan carries the row from R057 through NETB-CU15, and the table prints which network cabinets list 1050 to FW-08 or FW-09 and which keep a 2450 cold aisle.
  8. N-301-ENSheet N-301-EN: Tray drops into unit CU-08 and the calculated NIC and DPU jumper lengthsThe 1:50 detail is where unit CU-08 shows the drop from trays TL, TA and TB into the cabinet top, and where each GPU cabinet's 72 + 18 jumpers are given a calculated length into NETA-CU08 and into NETB-CU08.
  9. N-302-ENSheet N-302-EN: Which tray lands the trunks on the CVS and SPA/SPB cabinets, and how the fan-wall front zone is sharedThe trunk table gives every SPA cabinet 120 trunks on TA and every SPB cabinet 120 on TB, every CVS cabinet 60, and note 4 states that the 1,050 mm fan-wall front zone is shared in time.
  10. N-303-ENSheet N-303-EN: Calculated MMS4X00-NS uplinks from far-end unit CU-15, and the tray drops onto the cabinet topsThe uplink table is the point of the far-end detail: NETA-CU15 to CVS-A and SPA-1, SPA-2 and SPA-3, NETB-CU15 to CVS-B and SPB-1, SPB-2 and SPB-3, on MMS4X00-NS, with note 4 stating calculated routed lengths of 58.7–61.4 m and the module as 100 m stated with two patch panels.
  11. N-311-ENSheet N-311-EN: Clearances where section A-A cuts CDU-08A and GPU cabinets R043/R044Section A-A at X58145 is the clearance cut through CDU-08A and GPU cabinets R043/R044 boundary: the section draws R043, with 1,200 mm of GB300 tray withdrawal inside the 2,450 mm cold aisle, 1,000 mm of rear access to the CDU front, and no fan wall on this cut.
  12. N-312-ENSheet N-312-EN: A 1,050 mm front zone at NETB-CU11, shared in time with fan wall FW-08Section B-B at X78845 is the cut where network cabinet NETB-CU11 faces fan wall FW-08: 1,050 mm from the cabinet front at Y3350 to the fan-wall face at Y4400, used at different times for 1,000 mm switch withdrawal and 850 mm fan-wall service.
  13. N-313-ENSheet N-313-EN: TA and TB trunks enter spine cabinet SPA-2 from the top rear, with a 2,450 mm cold aisle in frontSection C-C at X48295 cuts spine cabinet SPA-2 where TA and TB trunks enter from the top rear, the cold aisle in front is 2,450 mm, and note 7 gives each of SPA-1..3 / SPB-1..3 120 trunks.
  14. N-401-ENSheet N-401-EN: NETA-CU08 lists SN5610 leaves, a 7U MPO-12 patch and an SN2201 by U, and NETB-CU08 mirrors that equipment on plane BThe unit-cabinet elevation shows where the north–south leaves, the compute rail leaves, the 7U MPO-12 patch and the SN2201 sit in NETA-CU08, and the table says NETB-CU08 mirrors that equipment with plane B.
  15. N-501-ENSheet N-501-EN: Plane-A trunks use TA only, plane-B trunks use TB only, and power and water stay below the floorPlane-A trunks use TA only and plane-B trunks use TB only, while NIC and DPU jumpers of both planes stay on TL, and the wet and power channels are under the floor.
  16. N-502-ENSheet N-502-EN: The highest fill drawn is TA at X49,095, at 25.5 %, and the trunk drop passes over TLSix tray sections print the fill at each tray's maximum-occupancy station and at its median station, and the Y–Z view shows the TA trunk dropping over TL into the cabinet.
