We have been trying (since our last major storage outage in November 2006) to get this product configured properly for our environment. The issue is that we run so much old software to manage our storage that it's a constant struggle to get things working together. Our storage team is too busy to devote time to getting products to help them operational. We need to come up with a plan to keep management software current. This includes all of our tools.
The product is excellent for the operational needs, but it's not something that I think our team would use well in engineering. I do see value in the storage architects using the product. We'll see how it pans out. The salespeople at Onaro are very aggressive, which can make them hard to deal with.
On a side note, their performance product looks very nice, and it's something the business side has been trying to get for years.
