Must you have ASM for install oracle RAC version 12 and next versions?
Hello,
1) I would like to know if it's necessary install ASM with Oracle RAC 12 and later versions.
In all official oracle docs say it's recommendable, but if you have netAPP you will add another layer because the responsible of the final administration and performance is the filer.

".. storage management and provisioning for the database has become much more simplified with a new feature called Automatic Storage Management (ASM). ASM provides filesystem and volume manager capabilities built into the Oracle database kernel. With this capability, ASM simplifies storage management tasks, such as creating/laying out databases and disk space management."
