Reduxio fit into our plans for replacing our aging EMC VNX5500. We were able to reduce our data center footprint from 50 rack units down to 8. The data dedupe or "No-Dupe" as they call it was the main reason for the reduced footprint. We also use VSphere and the API's that tie into VCenter work very well. Your able to carve out storage right from the VCenter web client. Reduxio may be less appropriate when used as a backup repository.
We were looking for a low cost and high IO performance storage option, and considered Netapp and EMC. Reduxio, as an early stage startup, offered us a test option on their beta site. After more than a year, we got a generally available version, and after an additional 3 months, we went to production.
