We had an issue with a new Exadata/ZFS environment where a clone database on
ZFS storage would return ORA-64307: Exadata Hybrid Columnar Compression is not
supported for tablespaces on this storage type.
That was an issue with the SNMP service on the ZFS not starting properly and
has now been resolved.
Based on that can someone confirm the following that seems to me to be true:
1. An Oracle database uses SNMP to verify the storage is either Exadata, ZFS
or Pillar.
2. There is no technical reason HCC could not work on any storage but for
marketing or other reasons, Oracle has decided to restrict it to only these
platforms.
