ASM Intelligent Data Placement

Database Overall → ASM

Disk drives have higher transfer rates and bytes per track on the outer tracks. This makes it preferable to keep the hotter data closer to the edge of the disk; that is, the lower numbered blocks. This feature enables ASM to identify higher performance disk regions. Most frequently accessed ASM files can be marked to be moved into the hot region and take advantage of higher I/O performance (for example, hot tablespaces and indices) and able to better meet the application I/O demand. This feature is only applicable when whole physical disks are presented to ASM versus local unit numbers (LUN).

Business Benefit: Most frequently accessed Oracle database files in ASM disk groups (ASM files) can be placed in hot disk regions to deliver higher bandwidth and reduce seek latency to meet the application I/O performance requirements.
