  • Patent number: 7584324
    Abstract: Admission of a new disk stream is based on the probability of overcommitting disk bandwidth based on parameters related to the disk. These fixed parameters are determined either by retrieval from the disk or by investigating the disk. Probability functions of the disk parameters may be obtained. Exemplary disk parameters may be average disk seek time, probabilistic determination of the amount of data exchange during a single exchange, and probabilistic information about reading versus writing.
