Hi Dave,
Sorry, don't think i can help to much then, we have one view and you can see all the array information in the storage tab plugin, but this is different to what you see in the vcenter summary (due to white space reclamation etc). it basically shows the same as using the 3par console and looking at the space saving for the exported vvol, summary looks like a fat volume (no space saving information).
Id expect you d see the dedup savings there.
Unfortunatly at the moment we are choosing AO over dedup.
let me know if you find this out as id be interested.
