We have had ROI in a few areas:

• With operational complexity reduced, operational incidents and troubleshooting don't exist anymore.
• Service benefit is a huge performance boost. Time to complete tasks have reduced dramatically, and now, we can complete all heavy tasks without any impact on the production traffic.
• Budget planning is very easy as we closed pricing ahead of all needed future upgrades, but we were surprised as the storage efficiency grows, we add more and more machines and we had savings that we didn't plan on.

Positive ROI.
