This topic describes how objects are stored on your iSeries™ server and lays the groundwork for the other topics in this section.
The iSeries server has a unique way of addressing storage. It views the disk space on your server and your server's main memory as one large storage area. This way of addressing storage is known assingle-level storage. The following diagram shows how single-level storage works:
When you save a file, you do not assign it to a storage location; instead, the server places the file in the location that ensures the best performance. It may spread the data in the file across multiple disk units, if that is the best option. When you add more records to the file, the system assigns additional space on one or more disk units.
