Which factors affect the performance of a disk drive?

What is an accurate statement about application virtualization?

An organization plans to deploy a new business application in their environment. The new
application requires 2 TB of storage space. During peak workloads, the application is expected to
generate 9,800 IOPS with a typical I/O size of 4 KB. Because the application is business-critical,
the response time must be within acceptable range.
The available disk drive option is a 15,000 rpm drive with 100 GB capacity. The number of IOPS in
which the disk drive can perform at 100 percent utilization is 140.
What is the number of disk drives needed to meet the application’s capacity and performance
requirements?

An organization plans to deploy a new business application in their environment. The new
application requires 4 TB of storage space. During peak workloads, the application is expected to
generate 4900 IOPS with a typical I/O size of 8 KB. Because the application is business-critical,
the response time must be within acceptable range.
The available disk drive option is a 10,000 rpm drive with 200 GB capacity. The number of IOPS in
which the disk drive can perform at 100 percent utilization is 140.
What is the number of disk drives needed to meet the application’s capacity and performance
requirements?

An application generates 4200 small random I/Os at peak workloads with a read/write ratio of 2:1.
What is the disk load at peak activity for a RAID 1/0 configuration?

An application generates 4200 small random I/Os at peak workloads with a read/write ratio of 2:1.
What is the disk load at peak activity for a RAID 5 configuration?

An application generates 4200 small random I/Os at peak workloads with a read/write ratio of 2:1.
What is the disk load at peak activity for a RAID 6 configuration?

What is an accurate statement about a software RAID implementation?
