Symptom & Impact

Database and file workloads time out during concurrent bursts with high queue pressure.

Environment & Reproduction

Reproducible during backup plus ETL overlap windows.

Get-Counter 'PhysicalDisk(*)Current Disk Queue Length' -SampleInterval 5 -MaxSamples 10
Get-Process | Sort-Object IOReadBytes -Descending | Select-Object -First 10 Name,IOReadBytes,IOWriteBytes

Root Cause Analysis

Queue depth defaults exceed controller behavior, causing resets and long tail latencies.

Quick Triage

Identify top I/O producers and current queue metrics before adjusting policy.

Step-by-Step Diagnosis

Measure queue and latency per LUN and compare with controller limits.

Solution — Alternative Approaches

Reschedule competing jobs and distribute heavy workloads across additional LUNs.

Verification & Acceptance Criteria

Queue lengths normalize and application timeout alerts stop.

Rollback Plan

Restore original queue tuning and prior driver if response worsens.

Prevention & Hardening

Baseline queue behavior and include storage load tests in release gating.
