Abstract
Computer system which varies the number of read requests outstanding to hard disk drives based on the mix of sequential and random requests. If a sequential request is received, a limited number of requests are allowed to be outstanding. If the requests are random, a growing number of read requests can be outstanding as the random requests continue, until a maximum number of write requests are allowed to be outstanding.
