Comment on "Issues and Challenges in the Performance Analysis of Real Disk Arrays'
|
Abstract—We address an analysis of the SCAN disk scheduling, which approximates the mean seek distance as the ratio of maximum distance and disk_queue+1. We also comment on using the mean seek distance to estimate the mean disk response time.
