A partition cache has variable size prefetch cache and main cache partitions. The cache size management algorithm adapts automatically to the requirements of the sequential content in the I/O request stream. When longer prefetch packets are used and/or larger number of sequential runs are detected the prefetch cache is made larger by the cache manager. Otherwise, when the size requirements for the prefetch cache are reduced, the main cache size is made larger.
