# TECHNICAL SPECIFICATION: JiRack 236B Frontier Cluster  

**Document ID:** CMS-JR-236B-PROC-2025  
**Project:** JiRack Balanced Frontier Deployment  
**Lead Architect:** Konstantin Vladimirovich Grabko

## 1. COMPUTE SYSTEM (High-Density GPU Nodes)  
The deployment requires a minimum of two (2) fully populated 8-GPU nodes to achieve the necessary VRAM and throughput for the 108-layer dense architecture.  

| **Component**     | **Minimum Specification**         | **Required Feature for JiRack**                         |
|--------------------|-----------------------------------|---------------------------------------------------------|
| **Chassis**        | 6U - 8U Rackmount (e.g., NVIDIA HGX H100) | Support for 700W SXM5 GPUs                              |
| **Accelerator**    | 16x NVIDIA H100 80GB (SXM5)      | 1.28 TB aggregate HBM3 VRAM                             |
| **GPU Interconnect** | NVLink + NVSwitch (900GB/s)    | High-width Tensor Parallelism (TP)                      |
| **Processor (CPU)** | 2x Intel Xeon Platinum 8480+ (per node) | 224 total cores for BRE routing                         |
| **System Memory**  | 2TB DDR5-4800MHz ECC             | Weight-caching for 108 layers                           |
| **Local Storage**  | 8x 3.84TB NVMe U.2 (RAID 0)     | Sequential read for fast model loading                  |

## 2. NETWORKING & FABRIC (Low-Latency Backplane)  
Because the 236B model requires frequent cross-node communication (Pipeline Parallelism), **standard Ethernet is unacceptable**.  

- **Primary Fabric:** NVIDIA Quantum-2 InfiniBand (NDR 400Gb/s).  
- **Adapters:** 8x ConnectX-7 NDR InfiniBand cards per node (1:1 GPU-to-NIC ratio).  
- **Switching:** 1x QM9700 Quantum-2 Switch (64 ports of NDR).  
- **Features:** Must support GPUDirect RDMA and SHARPv3 (Scalable Hierarchical Aggregation and Reduction Protocol) to offload 14:1 GQA reduction tasks.

## 3. POWER & THERMAL MANAGEMENT  
Operating a 236B Frontier model at 100% duty cycle generates extreme thermal load.  

| **Parameter**        | **Specification**                                         |
|-----------------------|---------------------------------------------------------|
| **Peak Power Draw**   | 10.2 kW per server (~22kW total including switching)    |
| **Voltage**           | 200V - 240V AC (3-Phase Delta/Wye)                      |
| **Cooling Type**      | Rear Door Heat Exchanger (RDHx) or Liquid Cooling (D2C) |
| **Ambient Ops**       | 18°C – 24°C (64°F – 75°F) with N+1 Redundancy           |
| **Rack Rating**       | 48U Heavy-Duty (Static Load: 1500kg+)                   |
