It is a pooled storage model and volumes are no longer needed, so thousands of file systems can draw from a common storage pool, each one consuming only as much space as it actually needs.
Oracle ZFS offers high scalability, performance, robust data protection, efficient storage management, and seamless data replication, integrating easily with existing IT infrastructure. However, it involves high implementation and maintenance costs, limited third-party integration, and a complex setup process demanding expert knowledge. Performance can be inconsistent during peak loads, and scalability options are limited compared to competitors.
