1.
Based on the calculated disk service time of 7.57 what would be the response time at 20 percent versus 70 percent versus 99.9 percent of I/O controller utilization?
What do these response times explain?
2.
An application has 5,000 heavy users at a peak of 4 IOPS each and 2,500 typical users at a peak of 2 IOPS each.
It is estimated that the application also experiences an overhead of 8.0 percent for other workloads.
The read/write ratio for the application is 2:1.
Calculate RAID corrected IOPS for RAID 5.
