2. Physical to Logical Mapping

Mapping physical motherboard PCIe slots on the ASRock Rack ROMED8-2T layout to PCI Bus Addresses, NVIDIA software indexes, physical silicon GPU UUIDs, and active compute roles on host origami.

Motherboard Slot	GPU Model	PCI Bus ID	NVIDIA Index	Physical GPU UUID	Operating Role & Notes
PCIE7 (Gen4 x16)	ZOTAC GAMING GeForce RTX 5070 Solid OC (12GB GDDR7)	`81:00.0`	`1`	`dd40d876`	Active (180W Cap, Silicon Winner @ ~90k PPD/W)
PCIE2 (Gen4 x16)	NVIDIA RTX PRO 4000 Blackwell Workstation (24GB GDDR7)	`82:00.0`	`2`	`e1600107`	Active (145W Cap, Acquired Jun / Online Aug 16 in v2.0, ~112k PPD/W)
PCIE1 (Gen4 x16)	PNY NVIDIA RTX PRO 4000 Blackwell Workstation (24GB GDDR7)	`01:00.0`	`0`	`6f99ccc4`	Active (145W Cap, Original v1.5 Card, ~108k PPD/W)

Note: The Asus PRIME SFF-Ready OC GeForce RTX 5070 (18de45ee) from the v1.5 build has been retired from the active folding fleet and repurposed inside the refurbished origami v1 chassis as a giveaway workstation. See Fleet Docker Compose Architecture & Hardware Lifecycle for the standardized container configuration and graceful GPU swap procedure.

3. Hardware Upgrade Roadmap

Platform evolution chronology for node origami.

Phase 1 (v1.5 - Retired): Intel Core i9-7940X on X299 platform with 128GB DDR4 memory, 44 PCIe lanes, and 3x GPUs (1x RTX PRO 4000 Blackwell + 2x RTX 5070).
Phase 2 (v2.0 - Complete / Active): Full platform transformation to AMD EPYC 7543 32-core server architecture on ASRock Rack ROMED8-2T with 256GB 8-channel ECC RAM, Phanteks Enthoo Pro 2 Server Edition TG chassis, 128 PCIe 4.0 lanes, dual 10GbE networking, and 3x active GPUs (2x RTX PRO 4000 Blackwell in slots 1 & 2 + 1x Zotac RTX 5070 in slot 7).
Phase 3 (Future Expansion): 4 open PCIe 4.0 x16 slots remain available for additional workstation GPUs or high-density Blackwell accelerators.
