Speaking at E4 2013! … and some Exadata Patents good stuff Reply

I’ll be co-speaking with Tyler Muth at E4  and we will be talking about Performance Visualization… some of you may already know that I’m really a big fan of Tableau and just to give you an example on what the tool can do I’ve consolidated all the different viz that I’ve done during my sizing & performance gigs here http://goo.gl/xZHHY and Tyler has also been doing a lot of Exadata performance & benchmarking gigs lately and there were a couple of times where we collaborated on specific viz (him doing it on R) just to validate each other’s work. In short, we are passionate about this stuff. And we are going to be awesome :)

The session title is: Performance data visualization with Oracle R and Tableau

and here’s the abstract:


The effect of ASM redundancy/parity on read/write IOPS – SLOB test case! for Exadata and non-Exa environments 13

Last week I had a lengthy post at oracle-l that tackles Calibrate IO, Short Stroking, Stripe size, UEK kernel, and ASM redundancy effect on IOPS Exadata which you can read here
followed by interesting exchange of tweets with Kevin Closson here (see 06/21-22 tweets) which I was replying in between games at UnderwaterHockey US Nationals 2012 which we won the championship for the B division ;) I have my awesome photo with the medal here

This post will detail on the ASM redundancy/parity effect on IOPS… if… by changing the ASM redundancy (external, normal, and high) will it decrease the workload read/write IOPS or stay as is. I’ll walk you through the step by step on how I did the instrumentation + the test case itself then end with some results and observations.

Let’s get started!
