Abstract:
1. A method of assigning a task to a disk drive within a computer system, said disk drive having a total available physical storage space and a total available disk head time, said task having a physical storage space requirement and a disk head time requirement, the method comprising: calculating a remaining available physical storage space for said disk drive by subtracting physical storage space allocated to tasks previously assigned to said disk drive from said total available physical storage space; calculating a remaining disk head time for said disk drive by subtracting disk head time allocated to tasks previously assigned to said disk drive from said total available disk head time; comparing the physical storage space requirement and disk head time requirement for a new task with the remaining available physical storage space and remaining available disk head time for said disk drive; and assigning said new task to said disk drive when said physical storage space requirement for said new task does not exceed the remaining available physical storage space for said disk drive, and said disk head time requirement for said new task does not exceed the remaining available disk head time for said disk drive.
