I will present this session on September 6th 2011 in Dublin Ireland at 6:30pm (None Irish audience is welcome too, I promise to finnish in time for a pint of Guinnes :-) How does SQL Server really access the data and log files on the disk? What's done asynchronous and what's synchronous and what impact does that have on our queries and DML statements? How do you specify IO requirement and what are they to begin with? What I/O characteristics do different access methods, workloads and maintenance task have? What impact do features like database mirroring and replication have? What changes have occurred to the SQL Server startup? Which I/O Subsystems (including SSD) are best for which type of data and what's the impact if you choose a different one? Which files can be placed on the same volume and which should not? Thomas H. Grohser is a SQL Server MVP (SQL Server Performance Engineering). In the last 17 of his more than 24 years as an IT Professional, he spent the majority of the time exploring the deeper inner workings of SQL Server and its features while working for entertainment , pharmaceutical and other industry leading companies. The main focus of his work is to architect, plan and provide a reliable, highly available, secure and scalable infrastructure for and with the features of SQL Server. This covers all angles from hardware, network, storage systems, Operating systems, SQL Server configuration and the Data Access Layer of applications; Currently, he works at one of the largest SQL Server installations in the world processing hundreds of millions of transactions daily while moving peta bytes of data in a 24x7 environment ; Now its time to share all the findings and the gathered know how with the SQL Server community therefore he started speaking regularly at international conferences in North America and Europe and at local events and work closely with SQLCAT to make sure everyone interested can access the information.
