On previous multitasking data-processing systems, storage pools had to be created at a preconfigured size. This forced the customer to understand the internal workings of the machine or to accept some system default that was usually much too large. If the value chosen was too small, the customer had to re-IPL (initial program load) the system, selecting a larger size. Also, since the preselected storage pool size had to handle the maximum work load, main storage was wasted. These systems also used the best fit storage allocation technique which is slow and often results in unacceptable storage fragmentation.
