Fabric Capacity Planning: Lessons from Production

I wrote “Fabric Capacity Planning: Lessons from Production” to share practical, production-minded guidance on this topic.

Mistake 1: Starting Too Big

Started with F64 because “enterprise.” Spent money we didn’t need to.

Lesson: Start smaller. F32 was enough. Can always scale up.

Mistake 2: Not Monitoring

Hit capacity limits without warning. Users got errors.

Lesson: Set up monitoring from day one. Alert before hitting limits.

Mistake 3: Ignoring Patterns

Some days used 20% capacity. Others hit 90%. Paid for peak.

Lesson: Analyze usage patterns. Consider autoscale or lower base capacity.

What We Do Now

Start F32 for most workloads

Monitor closely with custom dashboards

Set alerts at 70% capacity usage

Review monthly and adjust as needed

Separate workloads by criticality

The Numbers

Previous: F64 = $8,000/month, often underutilized

Current: F32 = $4,000/month, better utilized

Savings: $4,000/month

The Lesson

Don’t guess at capacity. Start small, monitor, adjust.

Fabric makes it easy to scale. Take advantage of that.\n\n## Takeaways\n\nAdd a concise, personal takeaway and recommended next steps here.\n
