Question: Imagine that the storage system is now configured to contain two 40 GB disks in a RAID 0 array; that is, the data is striped

Imagine that the storage system is now configured to contain two 40 GB disks in a RAID 0 array; that is, the data is striped in blocks of 8 KB equally across the two disks with no redundancy.
a. How will the 40 GB of data be allocated across the disks?
Given a random request workload over a total of 40 GB, what is the expected service time of each request?
b. How can queuing theory be used to model this storage system?
c. What is the average utilization of each disk?
d. On average, how much time does each request spend waiting for the disk?
e. What is the mean number of requests in each queue?
f. Finally, what is the average response time for the disk requests?
