I rate it nine out of 10. It’s great, but not perfect. I have spoken at conferences in the past on behalf of Riverbed. I do believe strongly in the solution.

Understand your environment, ensure you have good storage in your main data centers, evaluate the product in a real-world environment, not just a test environment. Know that if a controller fails, that set of files will be unavailable until the controller comes back up. So, if you need branch office to branch office file sharing, look into other solutions, like Panzura or Nasuni storage.
