A customer tells a technical specialist that EMO stated XIV has a double drive failure problem
because XIV has a 180 drive RAID group.
What is the best response to this competitive statement?

A.
EMO has double drive failure issues as well.

B.
EMC deploys different drive tjpes and sizes making their reliability issues much more
complicated.

C.
EMC uses RAID protection. The high load on drives during RAID rebuilds, that cause dual drive
failures, do not exist on XIV.

D.
EMC employs wide striping across many RAID groups, so they have the possibility of high data
loss in the event of a dual drive failure too.
