I'm still not totally clear which product you're referring to, but it sounds like PCF's Redis tile.

That is deployed and run on Ubuntu. It's not possible to run Pivotal Redis on other distros of Linux. It's also not really necessary as the product manages everything from the VM up, including Ubuntu itself. Ops Manager & Bosh take care of all that, including keeping Ubuntu up-to-date.
