Oracle Disk I/O Tuning

Chapter 5:

Configuration of Automated Storage Management

Striping

 

In the layout of database files, we often see many hot spots where same disk or set of blocks are accessed more often than others. Often it results in large queues and does not take advantage of the concurrent disk I/Os.

Striping Oracle Database Files across multiple physical disk spindles improves the concurrency of access to hot spots, and generally improves the transfer rate for large reads and writes, and spreads the I/O load evenly across the available disks. Striping spreads the I/O load evenly across all the disks in the stripe. This makes it possible for the full I/O bandwidth of the storage hardware to be used to service any I/O workload. The trend towards using fewer, larger capacity disks makes it increasingly important to be able to use the full I/O bandwidth in this way.

When the striping is implemented at storage array or hardware level, Oracle Database files inherently gets the striping benefit. Striping can also be implemented using an appropriate volume manager tool.

ASM provides the facility of generic volume management type software for striping at host level. This will avoid any use of expensive striping software.
