A company plans to deploy a new application in their environment. The new application requires 5 TB of storage space. During peak workloads, the application is expected to generate 3000 IOPS with a typical I/O size of 3 KB. The capacity of each available disk drive is 750 GB. In addition, the maximum number of IOPS a drive can perform at with a 70% utilization is 90 IOPS.
What is the minimum number of disk drives needed to meet the application's capacity and performance requirements for a RAID 0 configuration?
