Storage vendors can use the vSphere API for Storage Awareness (VASA) to provide vSphere with information about specific disk arrays for tighter integration between storage and the virtual infrastructure. The shared information includes details on storage health status, configuration, capacity and thin provisioning. From an administration perspective, this level of detail can now be passed up through vCenter Server to the user.
- Gather information around specific disk array features (snapshot, dedupe, replication state, RAID levels, thin or thick provisioned, etc.) and status (health, troubleshooting, etc.)
- Make it easy for administrators to select the most appropriate storage resources when a VM is created based on high level details around capacity, performance and capabilities of the underlying disk
- Integrate with the Storage DRS and Profile-Driven Storage features of vSphere
These API's are included with the VMware vSphere Enterprise Plus Edition.
