Please answer the following about disk drive:
A disk drive has the following performance characteristics 10000 RPM rotation speed and Each track contains two hundred 512 byte sectors. The average seek latency is 4.9ms; the minimum and maximum are 1.1ms and 10.2ms respectively For these exercises, a stripe unit consists of 8KEB 1) What is the read and write service times for a single stripe unit on a single disk 2) What is the read and write service times for a single stripe unit on a RAID level 5 3) The following problems continue the above in which each operation accesses a total (3 pts) configuration composed of five disks? (Bonus: 5 pts) of 1 MB of "contiguous" data. What is the read and write service times for a 1 MB operation on a single drive? (3 pts) What is the read and write service times for a 1 MB operation on the RAID level 5 configuration composed of five disks? (Bonus: 5 pts) a. b. 4) The response times for these operations naturally depend upon the workload - as the workload increases the queueing time increases. Plot response time curves for the four operations above; you are to assume the usual M/M/1 model for the disk drive operation queue. (Bonus: 10 pts)Step by Step Solution
