http://www.mssqltips.comThank you all for attending my MSSQLTips webinar today with Sumeet Bansal from Tegile Systems! In the presentation, I made reference to a disk stall collector that you can use to help collect and store database file-level latency statistics into a database for future reference, as well as an aggregation script that analyzes the metrics to provide a percentile analysis of the storage performance trends. These metrics can be presented to a storage administrator to help you demonstrate latency trends and help identify any performance challenges.

Disk Stall Collection Aggregation

In addition to the disk stall collector, which collects disk latency metrics at the SQL Server level, you can also use Perfmon to collect raw data at the Windows layer. I have a Perfmon setup guide on this site that you can use to set up Perfmon for 24×7 collection to overlay Windows-level statistics with the SQL Server-level statistics from the disk stall collector. Check out the guide here!

This Tuesday, June 23rd, at 3pm Eastern time I will be co-presenting a free live webinar with Sumeet Bansal from Tegile Systems at MSSQLTips entitled “Performance insights and tuning of Physical and Virtual SQL Servers”. Register for this free webinar here! All registrants will be registered for a ShootingAuthority.com raffle for  GoPro Hero digital video camera too!

Webinar Description:

This session will cover some of the best practices on setting up SQL Server in a virtual environment. You will learn what knobs and levers to tweak to get the best performance out of your setup. The speaker will cover various methods of collecting and analyzing performance data as well as pinpointing performance bottlenecks. You will also see a demo of performance you should expect from your virtualized SQL Servers. By the end of the session, you will have the information to improve utilization by leveraging virtualization for your SQL Server platform while delivering high performance. You will also have the necessary tools and data to have an educated conversation with your storage teams.
