- When handling a read request - the data could be stored in different locations.
- Part of the data might be in the cache.
- Part of it might need to be retrieved from the disk.
- We might have them in a "zebra" pattern:
|page1 ||page2 ||page3 ||page4
|cache ||disk ||cache ||disk
- Thus, a read request might generate several different read requests, to
different parts of the disk.
