Abstract:
A system for determining a total seek time required to access a physical disk storage device that stores data in a plurality of data blocks, said system comprising:A) collection means for collecting the number of disk accesses to each data block during a sample interval, B) first summing means for generating a first sum of the accesses to all the data blocks, C) second summing means for generating a second sum that is the sum of all the first sums, D) third summing means for generating a third sum that is a sum of the squares of all the first sums, and E) combining means combining the response to said first, second and third summing means for first, second and third sums to obtain the total interval required for all the disk accesses to all the data blocks in the physical disk storage device.
