With vSphere 4.1 came 150+ new features. One of these is called Storage IO Control or SIOC.And it has been a very popular subject in the last weeks. Just a small selection of blog posts on the subject:
- What to Expect When You Enable Storage I/O Controls in ESX 4.1 by Alex Bakman
- Storage I/O Fairness, SIOC, tying up some loose ends and Storage IO Control Best Practices all by Duncan Epping
The only thing missing was a way to automate everything surrounding SIOC. And so I decided to write a couple of functions to fill that gap.
