i really wish a product like acopia could work with live oracle data over nfs as well.  we would purchase this in a heartbeat.

We've done that, but when a single project out grows a volume, then we
start needing to shuffle data... it's a pain.

If I could have more volumes, then I'd use them over qtrees, but then
when an Aggr fills, I need to move volumes.  It's a pain.

That's why I like the idea of the Acopia product.  I wish NetApp would
realize that and come out with their own storage virtualization
product to put in front of backend NetApps.  Would be really nice.

Course I'm a mostly NFS only shop.
