Oracle Enterprise Manager 12c Heat Map• “Heat Map” tracking
– Database level shows which tables and partitions are being used
– Block level shows last modification at the block level
• Comprehensive– Segment level shows both reads
and writes– Distinguishes index lookups from
full scans– Automatically excludes stats
gathering, DDLs or table redefinitions

Direct NFS can issue 1000s of concurrent
operations due to the parallel architecture
Every Oracle process has its
own TCP connection
Parallel network paths for scalability

Why Direct NFS for Primary Storage?
• Lower CAPEX networking equipment– 10 Gb Ethernet or 40 Gb Infiniband networking options
• Simplified Management and Provisioning– IP based network management skill set– DBAs or Sys Admins can manage without Storage Admin– Reduced man hours reduces operating expenses
• High Performance– Direct NFS is optimally designed and tuned for
Database workloads– Superior performance to kernel NFS or iSCSI– Performance comparable to Fibre Channel

Oracle Intelligent Storage Protocol• Database and Storage Co-engineering
– Intelligence is in the code within both the database and storage
– Available ONLY with Oracle Database 12c and Oracle ZFS Storage Appliance OS 8 and above
• Storage Awareness of Database Workload– Database sends cues about each IO to the
storage– Over 70 database IO types mapped– Information used by storage to adaptively
and automatically adjust for optimal efficiency
