Tool to Evaluate I/O Cost \& Performance Input Values: Input Disk specifications: Constraints on Resource Utilization: Limit on disk time utilization = . Limit on utilization of SCSI buses = 0. Limit on utilization of I/O bus = 2) Consider the default input settings given by the tool. Only change is to make all resource utilizations to 100%. a. What units cost the most in this system? b. What can be done to make the system cost same for both 80GB and 40GB disks? Can it be done? 3) We have assumed the resource ytilizations to be 100% in the above cases. Is it the same in practice? Give reasons for your answer. 4) Give the key function for a transaction processing system and batch processing system. Transaction Processing: Batch Processing
