Data allocation in two dimensions is modeled as vector addition. The diskbandwidth requirementis determined by assuming FCFS scheduling, i.e., mean seek distance based on uniform accesses to disk blocks, mean latency one half of disk rotation time, plus transfer time which is negligible for acces...
• Disk-scheduling algo should be a separate OS module –allowing it to be replaced with a different algorithm if necessary. • Either SSTF or LOOK is a reasonable default algo g 21 How is the disk formatted? • After manufacturing disk has no information –Is stack of platters ...
