Not long ago VMware announced that the VMA (Virtual Management Appliance) that is currently used as a conduit between the array and virtual centre would be wound up and replaced by a new storage API that will provide even tighter integration with storage arrays.
The API is called VASA – Vmware Aware Storage API
With this new level of integration VMware are touting that operations such as DRS (Dynamic Resource Scheduling) could be applicable for storage, where I/O intensive VM’s will be moved to higher performance LUNs/Datastores by way of array integration.
This causes a “catch 22” though as tiered storage environments will already being taking care of this at this back-end. However if your subsystem doesn’t support tiering, this API will be great for dynamic movement high I/O VM’s.
