7.

Which of the following occurs in the event of an SSD failure in an XIV system?

The failed SSD's contents are rebuilt onto the hot spare SSD in the maintenance module. The module containing the failed SSD is phased out and all data is redistributed to theremaining modules. The extended read cache workload of the module with the failed SSD is redistributed to the remainingmodules.
