Test Your Expertise And See If You Can Be A Considered A Software-defined Storage Whiz.


Questions and Answers
  • 1. 
    Which of the following is NOT a key attribute of software-defined storage solutions?
    • A. 

      Physical storage resources (e.g. individual hard disk drives, flash SSD, etc.) are “abstracted” and presented to the IT team as a single, logical resource pool(s) via a centralized storage management layer

    • B. 

      Storage services are tightly coupled to, or embedded within, host hypervisors

    • C. 

      Late binding management that allows storage policies to be defined and implemented at the same time that applications are provisioned

    • D. 

      Storage management delivered on a per-VM basis

  • 2. 
    True or False: Software-defined storage must be a software-only solution.
    • A. 

      True

    • B. 

      False

  • 3. 
    Please select all of the key aspects that apply to software-defined storage.
    • A. 

      Ability to run on x86 hardware

    • B. 

      No dependence on proprietary hardware

    • C. 

      Data placement handled by hardware-based RAID controllers

    • D. 

      Overall system availability can be achieved via software resilience rather than redundant hardware

  • 4. 
    Please select all of the benefits that software-defined storage brings to a software-defined datacenter initiative.
    • A. 

      Storage services delivered on-demand anywhere in the datacenter

    • B. 

      Storage silos are eliminated so IT investment can be directed towards application delivery

    • C. 

      Lower TCO by using open APIs to automate storage operations

    • D. 

      Align storage management constructs with virtual machine (VM) management

  • 5. 
    True or False: Software-defined storage requires large centralized arrays (e.g. SAN or NAS) to provide the necessary capacity for supporting large enterprise workloads. 
    • A. 

      True

    • B. 

      False

  • 6. 
    True or False: In software-defined storage the ‘brains’ of the storage system are centralized, while the data plane responsible for handling the lower-level data placement is distributed - but remains under the auspices of central control. 
    • A. 

      True

    • B. 

      False

  • 7. 
    True or False: Software-defined storage architectures should have the flexibility to leverage off-premise and cloud-based storage as a part of a single data fabric. 
    • A. 

      True

    • B. 

      False

  • 8. 
    In software-defined storage clusters, what helps drive the highest performance (Select all that apply)
    • A. 

      Hardware-based storage controllers using custom-design ASICs or FPGAs devices

    • B. 

      Intelligently keeping data local to compute resources to reduce transport latency

    • C. 

      Leveraging multiple storage controllers in the cluster to scale-out data management operations

    • D. 

      Native use of flash-based SSD to store the most in-demand data (i.e. data tiering)
