Exploring Disk Size and Oracle Disk I/O Performance
Bruce D. Rodgers
The purpose of this chapter is to re-visit the continuing argument that application performance (often measured in disk I/O) is optimized by deploying a large number of smaller-capacity disk drives in the database storage array. As storage requirements continue to grow exponentially, the drive capacity issue remains central to application performance.
The issues surrounding disk capacity/performance persist because of the notion that in random read/write environments more disks moving simultaneously is optimal. The notion of striping data (RAID 1) to initiate concurrent disk drive read/writes has been an effective means of generating disk performance gains. The ...
