A customer wants your help in deciding if their existing VNX array can be used to do back up to disk, instead for tape backups.

The customer has a unified VNX that is fully populated with 125 disks. When looking at analyzer data for the array, you see that it has a consistent utilization of over 70% on both SPs.
According to EMC best practices, what do you recommend to your customer?

A.
The array should not take on additional load.

B.
The VNX is not supported as a backup-to-disk target.

C.
The array can be used, but they must add an additional SP to the array.

D.
The array can be used, but they will need an additional blade.
