P2000 G3 VAII support and thin-provisioned virtual disks

I've got 3 hosts with storage from an FC -connected P2000 G3 array that are running a Progress DB application that MAY be experiencing sub-ideal performance due to the VM disks being thin-provisioned. The datastore is created on a 4-disk RAID 10 LUN, so there should be sufficient IOPS and throughput for the application.

 

But the vendor is blaming the thin-provisioning of the virtual disk.

 

For various reasons storage-vmotioning to change the disk to thick may be a challenge (available space, etc ....)

 

The specific questions for your consideration:

 

1)How likely is it that the VM disk being thin-provisioned would cause discernable performance issues with a DB server?

2)Would installing the vCenter plugin that apparently is VAII integrated and has the ability to off-load some zeroing and other storage tasks address this issue?
