Proposed starting configurations. Platform limits do not guarantee every component combination; final configurations require validation.
| Specification | 4U AIO | 5U AIO |
|---|---|---|
| Platform | Supermicro AS-4125GS-TNRT | Supermicro AS-5126GS-TNRT2 |
| Proposed accelerators | 2 × RTX PRO 6000 Max-Q; expansion to four after validation. | 4 × RTX PRO 6000 Server Edition. |
| Accelerator capacity | Up to eight double-width, full-length cards, depending on model. | Up to ten double-width GPUs; eight recommended when reserving networking expansion. |
| GPU platform support | Max-Q, L40S, RTX 6000 Ada and others. RTX PRO 6000 Server Edition qualification remains TBD. | RTX PRO 6000 Server Edition, L40S, H100 NVL, H200 NVL and MI350P. |
| Proposed CPU / RAM | 2 × EPYC 9355 · 768 GB RAM | 2 × EPYC 9355 · 1,152 GB RAM |
| CPU / memory capacity | Dual EPYC 9004/9005 · 24 DIMMs · up to 6 TB. EPYC 9005 requires board revision 2.x. | Dual EPYC 9004/9005 · 24 DIMMs · up to 6 TB. |
| Storage | Four NVMe + two SATA 2.5-inch bays, plus one M.2. Proposed RAID10 data: 15.36 TB usable; boot mirror: 1.92 TB usable. | Eight NVMe + two SATA 2.5-inch bays, plus one M.2. Same proposed starting storage, with four NVMe bays remaining. |
| Networking / expansion | Dual 10GbE and dedicated BMC. Optional faster NICs. Default nine PCIe x16 slots, subject to occupied positions. | Dual 10GbE and dedicated BMC. AIOM and PCIe networking expansion. Up to 13 PCIe x16 slots, subject to GPU layout. |
| Power | 4 × 2,000 W Titanium; 2+2 or 3+1 redundancy. Available output depends on input voltage. | 6 × 2,700 W Titanium; 3+3 or 4+2 redundancy. 200–240 V AC input. |
| Cooling | Air cooling with eight heavy-duty fans. | Air cooling with up to ten heavy-duty fans. |
| Installation | 737 mm chassis depth. Server-room placement proposed. Measured noise, loaded weight and final circuit sizing TBD. | 786.1 mm chassis depth. Server-room/datacenter placement proposed. Measured noise, loaded weight and final circuit sizing TBD. |
The 5U offers greater power and expansion headroom for higher-power GPUs, additional NVMe storage and networking. Equivalent hardware is not automatically faster in 5U; both platforms support the same maximum host-memory capacity.
Optional NIC models and final component populations remain subject to qualification.
