At VMworld I met up with the guys presenting the Storage I/O Control session, Irfan Ahmad and Chethan Kumar. As many of you hopefully know Irfan has always been active in the social media space (virtualscoop.org). Chethan however is “new” and just started his own blog.
Chethan is a Senior Member of the Performance Engineering team At VMware. He focuses on characterizing / troubleshooting performance of Enterprise Applications (mostly databases) in virtual environments using VMware products. Chethan has also studied the performance characteristic of the VMware storage stack and was one of the people who produced this great whitepaper on Storage I/O Control. Chethan just released his first article and I am sure many excellent articles will follow. Make sure you add him to your bookmarks/rss reader.
Running Virtual Center Database in a Virtual Machine
I just completed an interesting project. For years, we at VMware believed that SQL server databases run well when virtualized. We have illustrated this through several benchmark studies published as white papers. It was time for us to look at real applications. One such application that can be found in most of the vSphere based virtual environments is the database component of the vCenter server (the brain behind a vSphere environment). Using the vCenter database as the application and the resource intensive tasks of the vCenter databases (implemented as stored procedures in SQL server-based databases) as the load generator, I compared the performance of these resource intensive tasks in a virtual machine (in a vSphere 4.1 host) to that in a native server.
Thanks for cross-posting this Duncan, and Chethan’s just got another rss reader. And yes, 3D graphs are now very popular also, as I see.
Thanks for the introduction Duncan. Hope readers will find my articles useful.
