Prole-driven and policy-based storage
The VASA provider supports prole-driven storage management by categorizing virtual disks based on performance and reporting its
performance capability to vCenter. You can use this information to establish proles based on specic application performance
requirements. Benets of this approach are:
• Rapid and intelligent provisioning of applications
• Application service levels that match available storage
• Information on the available storage pool
vSphere policy-based storage management enables you to further provision VMs by automating datastore placement decisions.
