Here are some random notes I took during a presentation to Storage IO Performance this morning:
- SSDs: Still not a 'solid state' business - http://bit.ly/cdqA1b - "False expectations" and why they "won't replace hard drives"
- A PRAM and NAND Flash Hybrid Architecture for High-Performance Embedded Storage Subsystems - http://bit.ly/95ZY83
- Resistive RAM Gains Ground - Faith in phase-change memory falters (IEEE Specturm) - http://bit.ly/cBpLB7
- SQL Server Best Practices Article - Predeployment I/O - http://bit.ly/9iybIa (great 2007 white paper on SQL storage)
- Disk Subsystem Performance Analysis for Windows - from 2004, but still very interesting - http://bit.ly/b2uXU1
- Design Tradeoffs for SSD Performance (from Usenix08) - http://bit.ly/9NjDGp
- Resource Monitor shows disk activity per process. In Windows 7, run resmon.exe and go to the "Disk" tab. http://bit.ly/c3jETW
- XPerf - Windows Performance Toolkit - http://bit.ly/aFQqvm - Invest the time to understand ETW and XPerf. It will pay off.
- Two-minute Introduction to XPerf - http://bit.ly/dApsVU
- Reducing Disk I/O Performance Sensitivity for Large Numbers of Sequential Streams - http://bit.ly/9gfWFL
- TANSTAAFL - There ain't no such thing as a free lunch - http://en.wikipedia.org/wiki/TANSTAAFL (also applies to IO perf)
- Know your storage path - from the app to the platter - Drivers, device property configuration, hardware configuration
