No, it's barely functional. It's got a lot of promise, but lacks some very basic features I'd have expected in 1.0. Storage performance management is the achilles heel of most storage vendors, and this is no exception. I hope Netapp will put together some sort of focus group to guide the next few iterations. It really does have promise- of all the useless performance applications I've used, this one does the coolest useless tricks... like their algorithm for determining bully volumes and telling you which layer the problem is at.
