However, each image will have five-hundred 64kB metadata files associated with it. They currently have six years worth of archived data. They will need to migrate to the new solution and they need to plan for an additional three years of archive capacity.

Which solution would you recommend to fit their capacity needs?

Options:

A.

24 NL-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity

B.

18 NL-Series nodes with N+2:1 protection policy providing 2078 TiB of useable capacity

C.

24 X-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity

D.

12 NL-Series nodes with N+2 protection policy providing 1300 TiB of useable capacity
