Selected Answer: D
A vault is a location to dump the contents of cache to nonvolatile storage during a power failure. Vaulting is the process of dumping that data to a safe location. (From: PowerStore Concepts and Features, Pag 23).

D - for sure! The last two or four slots (dependent on the model) must be populated with NVMe NVRAM devices and are used for write cache and vaulting.  Slots 0 through 20 are reserved for data drives for all PowerStore models.  Slots 21 through 24 are reserved for NVMe NVRAM devices for all PowerStore models.
