The VMworld conference organizer just sent me feedback from my presentations at VMworld 2010 in San Francisco. He also sent me my VMworld Europe schedule, which I want to share with you. You’ll have seven opportunities to catch me talking performance at the show and many more to catch me talking trash at a local pub. Here is my schedule and some comments on what you can expect at each appearance.

Databases, Storage, and Solid State Disks
September 20th, 2010
Sep, 20 2010
A colleague of mine dropped by my desk on Friday to talk about storage best practices for virtualized databases (SQL Server in this case). He observed a VMware deployment where the data and log files for a SQL Server virtual machine were consolidated on a single VMFS volume backed by a RAID 5 LUN. ”Is this a VMware best practice?” he asked. ”Should you not put the redo logs on a RAID 10 LUN?” The answers are ‘no’ and ‘yes’, respectively. And with the solid state disk (SSD) auto-tiering from EMC (FAST) the second answer is an emphatic “YES!”

Eric Siebert is doing is twice-annual vote on the best virtualization blogs. There are a huge number of blogs on the selection list so sheer volume is going to drown a few out. I have no way to call out all the excellent work by my friends across the globe. But I do want so share one thought and three recommendations to help your voting.
Optimizing vSphere for Hyper-threading

VMware’s Jeff Buell has been looking into High Performance Computing (HPC) in support of a new addition to the office of the CTO. Jeff just posted an article on VROOM! showing outstanding memory bandwidth in vSphere virtual machines. No one should be surprised by this–virtual machine memory bandwidth has rarely been a problem. But Jeff did discuss a advanced configuration parameter that should pique everyone’s curiosity: NUMA.preferHT.
Chargeback Resistance (with Survey Results)
September 8th, 2010

A few weeks ago I posted a survey asking for your thoughts on chargeback in virtual infrastructures. The results I received confirmed my observations of the scarce use of chargeback policies among VMware’s customers. I have written before that I think this is a mistake. And by bundling VMware Chargeback with the recently announced vCloud Director it appears that VMware agrees with me.
