Which configuration provides the needed usable capacity using N+2:1 protection, and requires the least amount of rack space?

A customer plans to replace an existing array that is supported by the MiTrend Workload Profile Assessment (WPA) service. You receive performance data from the customer and run a WPA report that shows the array has 50TB of usable capacity.

In discussions with the customer, you learn the content is comprised of four million 6MB files and 400 million 64KB files. The customer explains they have a small budget and very limited rack space available in their datacenter. Performance is not a concern because the files are rarely accessed.

Which configuration provides the needed usable capacity using N+2:1 protection, and requires the least amount of rack space?
