IBM E1350 HPC Product

Situation

In the early 2000s, high-performance computing was dominated by expensive proprietary supercomputers. IBM recognized an opportunity to productize commodity Linux clusters for commercial HPC markets, but needed to translate academic concepts into enterprise-grade solutions.

IBM was developing the E1350 HPC cluster product to:

• Make supercomputing accessible to commercial customers
• Establish standards for cluster architecture and deployment
• Create repeatable deployment methodologies
• Build knowledge base of best practices for HPC operations

The challenge was creating consistent, supportable HPC solutions that could be delivered reliably across diverse customer environments.

Task

As Enterprise Architect supporting the E1350 product development, I contributed:

• Whitepaper & Product Vision: Authored the whitepaper that influenced the product development direction
• Documentation & Architecture: Create architectural documentation and reference designs
• Best Practices: Establish best practices for deployment, configuration, and operations
• Testing & Validation: Test deployment models and software configurations
• Monitoring & Management: Develop systems management and monitoring practices
• Network Architecture: Define best practices for HPC network configuration
• GPFS Deployment: Establish practices for parallel file system deployment
• Reference Architecture: Create reference architectures for different HPC workloads

This required hands-on technical work across hardware, software, networking, and storage to establish proven patterns that could be repeated across customer deployments.
