STORPORT: Reading an ETL trace
One of the things I enjoy most is diagnosing storage latency. I honestly couldn’t tell you why I enjoy it so much; but, I just do. When it comes to storage in Windows one of the best things you can do is capture an ETL trace for the STORPORT driver.
PaaS and the ever changing role of the DBA

Query tuning 101: What’s a probe residual?
Query tuning is an important process that will probably never go away and sharpening your tuning skills is always a good idea.
