The HPC & EDA Challenge​

High-performance computing workloads demand more than just raw processing power. They require robust cloud infrastructure capable of handling both intense parallel processing and massive data flows. In the realm of chip design, EDA workloads are emblematic of these challenges. Here’s why:

• Intensive Data Processing:
  EDA involves running numerous simulations to fine-tune chip designs. These simulations are critical for ensuring accuracy and reliability—factors that can make or break a silicon design.
• Diverse Workload Patterns:
• Frontend Workloads: These focus on logic design and functional verification. They consist of thousands of short-duration parallel jobs characterized by randomized I/O operations—imagine millions of tiny file reads and writes happening almost simultaneously.
• Backend Workloads: These tasks transition the design from logic to physical mappings, involving sequential operations on larger files as the chip design moves toward fabrication.

Traditional cloud file systems often fall short when confronted with such mixed and intensive I/O demands. This is where Azure NetApp Files steps in, engineered specifically to meet the low latency and high throughput requirements of modern EDA processes.

What Sets Azure NetApp Files Apart​

Microsoft Azure’s investment in NetApp’s technology isn’t just another infrastructure update; it’s a strategic move to future-proof chip design. Here are the standout features:

1. Unmatched Performance​

• Lightning-Fast Throughput:
  Performance benchmarks using the SPEC SFS EDA_BLENDED test have shown that Azure NetApp Files can deliver up to ~10 GiB/s throughput. This means that even the most data-intensive simulations can run without the bottlenecks common to conventional storage systems.
• Ultra-Low Latency:
  With latency figures consistently under 2 milliseconds (and edge performance reaching slightly higher milestones at around 7ms), the system ensures that both frontend and backend workloads operate without delay—a critical factor for time-sensitive chip design iterations.

2. Scalability for Enterprise Demands​

• Handling Massive Workloads:
  Azure NetApp Files is engineered to handle storage volumes up to 2PiB and support compute clusters of up to 50,000 cores. This robust scaling ensures that as data grows—and simulation complexity increases—the performance remains consistent.
• Simplified Data Management:
  Instead of juggling numerous smaller volumes, large volumes simplify data handling and deliver superior performance. This consolidation is vital for EDA workflows, where managing disparate file groups can slow down the entire design process.

3. Operational Simplicity & Cost Efficiency​

• Ease of Use:
  Azure’s integration means that managing these resources is as simple as a few clicks in the Azure Portal or through automated APIs. This user-friendly approach reduces the administrative overhead and allows engineering teams to focus on design innovations rather than storage management.
• Cost-Effective Tiers:
  With features like “cool access” for reducing storage costs and reserved capacity options that deliver savings beyond pay-as-you-go models, organizations can optimize their budgets without compromising on performance.
