An application has 1,000 heavy users at a peak of 2 IOPS each. It is estimated that the application also experiences an overhead of 20 percent for other workloads. The read/write ratio for the application is 2:1. Calculate RAID corrected IOPS for RAID 1/0, RAID 5, and RAID 6. For the question above , compute the number of drives required to support the application in different RAID environments if 10k rpm drives with a rating of 130 IOPS per drive were used.
