Aim of disk management subsystem:
- handles mapping from database ID to disk address
- transfer blocks of data between buffer pool and disk
- also attempts to handle disk access error problems (retry)
Note: DBMSs typically do not deal with the raw disk
- mapping from
PageId to disk is via filesystem
