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