    • A system that has the management software that can provide access to its sets of hard drives or tape libraries for the purpose of data access and storage.
    • A system that handles the communication of data from end users to its storage location and provide confirmation on successful storage.

12. Situation: Disk Domain A has 40 disks, Disk Domain B has 20 disks. True or False: the rebuild time for a failed disk in Disk Domain B is longer than for a failed disk in Disk Domain A.

    • TRUE

14. What is the main difference between mechanical drives such as SAS with solid state drives (SSD)?

    • The lifespan of hard drive.
    • The presence of mechanical parts.
    • The capacity of hard drive.
    • The performance of the hard drive.

15. If no data migration plan is set, with SmartTier enabled, there will be no data movement at all between tiers.

    • TRUE
    • FALSE
