PASSMN September 15, 2009 Monthly Meeting

Posted by denglishbi on September 2, 2009

The next PASSMN Minnesota SQL Server User Group meeting is coming up.  The meeting is on Tuesday, September 15 from 3:00 PM to 5:15 PM.  You can visit the local site to get registered at http://www.mnssug.org or click the link to Register Here.

This month the topics are:

SQL Server and Partition Alignment (Speaker: Jimmy May, Microsoft) – Now that SQL Server wait stats are formally documented & DMVs are available, disk partition alignment may be the best kept secret related to database performance optimization. In combination with stripe unit size & file allocation unit size, learn how you can increase I/O throughput by 10%, 30%, & under some circumstances even more. Many customers are unaware of partition alignment. Even experienced disk administrators may be unfamiliar with it. Explanations are often initially met with disbelief. Engineers familiar with the topic may underestimate its importance. For example, some customers think it is useful only for Microsoft Exchange Server. In fact, partition alignment is important for all servers from which high performance is expected, especially SQL Server. Each month I encounter customers with unaligned storage. Until existing misaligned partitions created using Windows Server 2003 or Windows 2000 Server are rebuilt properly, disk partition alignment will remain a relevant technology.   

Jimmy May  is a Principal Performance Engineer for Microsoft’s Assessment, Consulting, & Engineering (A.C.E.) Services & works for Team Lee. He is the Founder & Visionary-in-Chief of SQL Server Pros & was formerly the Senior Database Architect for one of the world’s largest OLTP DBs. He is a founder & on the executive committees of both the Indiana Windows User Group & Indianapolis Professional Association for SQL Server. Jimmy lives in Indianapolis, Indiana with his lovely bride, Phyllis, & Fannie May the Wonder Dog. Subscribe to & read his blog at msdn.blogs.com/jimmymay.

Wait-Time Based Performance Management (Speaker: Janis Griffin, Confio) – Using Wait Time Analysis and Wait Types is a newer method for tuning SQL Server instances. As a result, there is often confusion on exactly what the data means. The issue typically centers around the fact the wait time data is analyzed at the wrong level or the collected wait time data is not detailed enough. This presentation will focus on these problems and review several real-life case studies of using SQL Server Wait Type data coupled with Wait-Time based performance analysis to solve the most difficult performance related issues.

Janis Griffin has over 20 years of DBA experience including design, development and implementation of many critical database applications. Before coming to Confio, Janis held DBA positions primarily in the Telecom Industry (15 yrs), working with both real-time network routing databases and OLTP business to business applications.
