I just wrapped up a Breakfast ‘N Learn at one of my customers on the topic of Storage Best Practices for VMware Environments. A storage agnostic view of things to keep in mind on the storage side of your VMware deployments.
Here is a quick hit of the server storage best practices that should be of value to all VMware users:

- Handle exceptions on a case-by-case basis
- Avoid use of extents
