Abstract:
1. A method, comprising: determining information about at least one disk which will be used to store information; using said information to determine whether to admit a new data stream, said using comprising determining a probability of overcommitting disk bandwidth from all of a first parameter related to disk seek time, a second parameter related to disk bandwidth, and a third parameter related to amount of data exchanged during a disk access, wherein said using further comprises comparing said probability with a rejection probability, and allowing the new data stream to be scheduled based on said comparing, wherein said using further comprises determining a parameter based on the relationship between a disk's average read bandwidth and average write bandwidth, determining a first percentage related to a disk bandwidth reserved for disk reading; and determining a second percentage related to an average amount of data to be retrieved relative to an average amount of data to be recorded based on calculations comprising reading and writing requirements for the data stream.
