1. FCFS Scheduling AlgorithmIn FCFS, the requests are addressed in the sequence they come in the disk queue.AdvantagesThe following are the advantages of FCFS scheduling algorithm:Simple Not complex Easy to implement No starvation Low overhead No indefinite delay Low overheadDisadvantagesThe following...
We report on a rather extensive simulation effort directed at evaluating the merits of two scheduling strategies, FCFS and SSTF, for moving-arm disks under stationary request arrival process. For First-Come-First-Served (FCFS) scheduling, analytic results for the mean waiting time are also given ...

Disk Scheduling (Cont (Cont.) ) • Several scheduling algos exist service disk I/O requests. • We illustrate them with a request queue (0-199). 98, 183, 37, 122, 14, 124, 65, 67 Head pointer 53 11 FCFS Illustration shows total head movement of 640 cylinders. 12 SSTF ...
功能:避免 spare sector 的轉向破壞 disk scheduling performance。 (五) Swap Space Management Disk 中用來儲存 swap out 的 process 或 page 的空間 (from virtual memory or medium term scheduler) 一般而言,預留的 swap space 大一點比較好,不要太小,以增加安全性。
