An application specifies a requirement of 200 gb to host a database and other files. it also specifies that the storage environment should support 5,000 iops during its peak workloads. the disks available for configuration provide 66 gb of usable capacity, and the manufacturer specifies that they can support a maximum of 140 iops. the application is response time- sensitive, and disk utilization beyond 60 percent does not meet the response time requirements. compute and explain the theoretical basis for the minimum number of disks that should be configured to meet the requirements of the application.

60 minimum number of disks that should be configured to meet the requirements of the application.

Explanation:

Requirement of space for database = 200 GB

Usable Capacity for configuration = 66 GB

so the size requirement can be calculated as below :

Size requirement = 200/66 = 4 Disks

IOPS supported during peak processing cycle = 5000 IOPS

Max No. of IOPS supported = 140 IOPS

AS,The application is response time sensitive, and disk utilization beyond 60 percent does not meet the response time requirements, so,

IOPS requirement can be calculated as

IOPS requirement = 5000 IOPS/ (140x0.6 IOPS) = 60 disks

b. xor is the correct answer
