ZS3 storage has a number of advantages over non-Oracle storage for Oracle Database workloads. This includes (in no particular order):

• Support for Hybrid Columnar Compression (HCC)
• Oracle Intelligent Storage Protocol (OISP)
• Hybrid storage pools
• dtrace analytics and others.

There are a bunch of whitepapers here with details:
