Repeat 6.19.2 for a large disk farm operated by an online backup company. Does upgrading to either RAID 0 or RAID 1 make economic sense given that your income model is based on the availability of your server?

Exercise 6.19.2

Given that your company operates a global search engine with a large disk farm, does upgrading to either RAID 0 or RAID 1 make economic sense given that your income model is based on the number of advertisements served?

For disks in the table in Exercise 6.18, assume that your vendor offers a RAID 0 configuration that will increase storage system throughput by 70% and a RAID 1 configuration that will drop AFR of disk pairs by 2. Assume that the cost of each solution is 1.6 times the original solution cost.
