Configuring storage for performance

Increasing the I/O rate and decreasing the frequency of disk access to move data between real storage and storage devices is key to good performance.

About this task

To meet the diverse needs of application data, a range of storage options is available, each with different access speeds, capacities, and costs per megabyte.

This broad selection of storage alternatives supports requirements for enhanced performance and expanded online storage options, providing more options in terms of performance and price.

The levels in the Db2 storage hierarchy include real storage, storage controller cache, disk, and auxiliary storage.
