AI Black Box – IBM Watsonx Turnkey Solution (On-Premises Data-Sovereign Deployment on IBM Fusion HCI) 

Wed October 08, 2025 05:12 PM

1. Executive Summary

The AI Black Box is a self-contained, on-premises AI and data ecosystem built on IBM Fusion HCI, designed to deliver the full spectrum of Watsonx capabilities—including AI, data integration, intelligence, governance, orchestration, and security—while ensuring complete data sovereignty and regulatory compliance.

Built for high-performance AI workloads, this solution integrates GPU-accelerated compute, high-throughput storage, and large memory bandwidth to support large language models (LLMs), RAG, and generative AI within enterprise-controlled environments.

2. Strategic Objectives

  • Achieve Data Sovereignty: Keep all data, models, and governance local to the enterprise.

  • Enable High-Performance AI Compute: Leverage Fusion HCI’s scalable GPU and memory architecture.

  • Establish Trusted AI Governance: Enforce transparency, lineage, and auditability with Watsonx.governance.

  • Simplify Deployment: Pre-integrated Watsonx suite on a single converged hardware and software stack.

3. Solution Overview

The AI Black Box unifies Watsonx and Guardium under a Fusion HCI foundation:

Layer IBM Component Purpose
Data Integration Watsonx.data Integration ETL/ELT, replication, streaming
Data Lakehouse Watsonx.data Storage, query, embeddings
Data Intelligence Watsonx.data Intelligence Governance, quality, lineage
AI & Orchestration Watsonx.ai, Watsonx.orchestrate Model lifecycle, automation
Security & Compliance IBM Guardium Access control, encryption, audit
Infrastructure IBM Fusion HCI Compute, GPU, storage, and memory platform

4. Platform Foundation – IBM Fusion HCI

The IBM Fusion Hyper-Converged Infrastructure (HCI) provides the physical and virtual foundation for the AI Black Box.
It delivers optimized compute density, high-throughput storage, and GPU scalability, making it ideal for Watsonx workloads.

4.1 Compute & GPU Acceleration

  • NVIDIA L40S, A100, or H100 GPUs per node (scalable up to 8 GPUs/node).

  • Supports mixed precision (FP16/BF16/INT8) for AI model training and inference.

  • AI performance acceleration through CUDA, TensorRT, and ROCm frameworks.

  • Horizontal scalability: 50% GPU capacity expansion every 6 months (target baseline 5× growth over 5 years).

  • Dynamic GPU pooling for Watsonx.ai, Watsonx.data, and Watsonx.orchestrate workloads.

4.2 Memory & Compute Performance

  • High-memory configuration per node: up to 4 TB DDR5 / CXL-enabled RAM.

  • Memory bandwidth: 400–800 GB/s per node for large model workloads.

  • Optimized for parallel training and real-time inference.

  • Supports NUMA-aware scheduling for AI data locality and performance consistency.

4.3 Storage Architecture

  • NVMe-based tiered storage (All-flash or hybrid configurations).

  • Supports software-defined storage with Red Hat OpenShift Data Foundation (ODF) or Ceph.

  • Throughput: 25–50 GB/s per node; IOPS: >2M per cluster.

  • Data protection: Snapshots, replication, encryption at rest, and Guardium-integrated access control.

  • Scalable to petabyte-class capacity, supporting multi-tenant Watsonx lakehouses.

4.4 Network & Connectivity

  • 25/100 Gbps Ethernet or InfiniBand fabric.

  • Low-latency RDMA for GPU cluster interconnects.
