Disk IO and the Data Warehouse 3.88 http://spkr8.com/t/3155

Description:

Data Warehouse load patterns, schema design, queries are all different than OLTP systems, shouldn’t your storage solution be different too? This session will look at both physical and logical disk layout and their effects on Data Warehouse performance. There is a whole world of technical jargon and acronyms, we will demystify some of those, understand where to look to find bottlenecks, understand your SAN, and most importantly, why you care about disk performance. To tie all of these parts together we will touch upon some partitioning and compression and monitoring topics that SQL Server 2008 offers. When you are done with this session, you will be able to not only understand your SAN admin, but they will understand you; as you are empowered with some recommendations for effective disk layout for warehouse storage!

I enjoyed the presentation and Stefan's obvious knowledge of the subject. The SQLIO and PerfMon demos were interesting and well presented, demonstrating the points he made during the discussion. I wish he would have shown a little more on how to know your SAN better, how to determine number of disks, etc... Easy to follow discussion and I would recommend it.

I appreciated that Stefan was willing to produce some hard and fast numbers even if "it depends" makes the most sense. I would have liked to see some examples of overworked disk I/Os or excessive throughput, just for comparison. As a developer, I found the first part of the presentation more interesting than the second, as I don't tend to use the monitoring tools very often.
