As Tanel told, HCC Support is decided at the tablespace level. If you
have any datafile on non HCC 'supported' Storage, Oracle tries its
best to force you in non-HCC land.
The whole game is pure marketing: only Exadata can support HCC decompression. ANY other storage loads all tasks of HCC compression and de-compression onto database-CPUs. There is no difference between ZFS/Pillar and something else like your EVA - except Oracle Marketing decision <=> $$$
