For many engineers, interpreting disk I/O is a black art. Yet analyzing perfmon, wait stats, and virtual file stats is often straightforward. I wish someone would have told me this 15 years ago!
Next week, at SQL Saturday Redmond (#SQLSat511), I will be sharing authoritative, clear guidance on collecting & interpreting disk I/O metrics – here’s a sneak peak.
The Counters That Count
This is the session I wish someone had offered me 15 years ago:
- There are at least 46 disk I/O counters in perfmon. I will introduce the six authoritative counters—including the unequivocally single most important counter in diagnosing storage bottlenecks.
- Wait stats are vital for SQL Server performance troubleshooting. To interpret them effectively, I’ll demonstrate how to filter benign weights and derive columns revealing actionable info.
- The raw output of virtual file stats DMV is nearly useless. Yet leveraging straightforward derivations easily exposes essential insights.
- There’ll be live demos that will show real-time use cases. I’ll put my scripts to work and find your environment’s hot spots in moments, and you can learn how to build a #DataDriven evaluation of your own environment.
SQL Saturday Redmond

By now, Tier 1 apps deployed on flash are ubiquitous. However, Tier 2 apps often remain relegated to spinning media. This presentation explains the economics of consolidating on flash. Owing to the SQL Server core licensing model, licensing a 2-socket commodity server can cost up to $500,000 or more! Consolidating instances on flash can—and does—save hundreds of thousands to millions of dollars. This presentation provides real-life case studies showing such real-life savings.SQL Server 2016 AlwaysOn AGs Break-through Perf Enhancements
SQL Server 2016 provides significant performance enhancements which permit us to more fully leverage hardware and licensing investments including processors, storage, network, and core licensing. Learn the new! improved! AlwaysOn AGs feature set, including the exciting new performance enhancements—and how flash is required to leverage them.
