Which is the benefit of RAID?

What is the stripe size of a five-disk RAID 5 set with a strip size of 32 KB?

What is the stripe size of a five-disk RAID 0 set with a strip size of 64 KB?

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

Thirteen switches with 12 ports are connected in a full mesh topology. How many ports are available for host and storage connectivity?

Determine the maximum IOPS that could be performed with this disk for the application. The average I/O size of an application is 64 KB. The following specifications are available from the disk manufacturer: average seeks time = 5 ms, 7,200 RPM, and transfer rate = 40 MB/s.
