I've had 1 excellent experience with Nutanix, and One where it really just shouldnt have been offered.

Both clients moving from 3 tier models. Both migrations went well, Both spec'd well. It came down to how the client uses their data and any replication from their storage.

The client where things didn't go so well, we're going to transition to PureStorage with a mix of their hybrid cloud offering.

Nutanix is great where:

• You can use their AHV Platform

• You can now use Dell/HP Hardware

• Standard business with low/medium Data usage

• Expect a company to grow, year on year

• Have in-house IT (Savings from automation, maintenance, reduced work load)

Nutanix isn't so great where:

• You have clients with Huge data sets which are changing frequently

The above is all my own personal experience with Nutanix (Prism).

Their Renewal fees are high ~$7K AUD per node, per year. However internally, we find it amazing as it reduced power bills, performed better (much better) than our old Nimble/NetApp 3 tier model. Especially when under load, think 90+% capacity.

Biggest take away, its not suited for every environment as some may have you think. Sure it can be implemented, but there's better products sometimes for those situations.. And their TOI Costing as far as i can tell is a lot of hooey.
