Hold your horses. That doesn't mean that you can now go creating FlexCache volumes all over the place in ONTAP. There's no magic that can do that. That just means you still need to get a license, but it costs $0.00! Go bug your NetApp account team to go get you one. I
n a future ONTAP version, you will be able to create FlexCache volumes without a license. This may even be a P release! (All the more reason to upgrade to P releases)
