What is the correct system hierarchy of SC Series array storage virtualization?

Certification Exam DES-1721: Dell EMC Specialist - Implementation Engineer, SC Series Dell-EMC Dell-EMC-DES-1721 4-3093089763
Select the answer
1 correct answer
The correct system hierarchy of SC Series array storage virtualization is:

1. Volume
2. Virtual disk
3. Storage tier
4. Disk folder
5. Physical disk

Why this is the correct order:

- Volume
A volume is the top-level storage object presented to hosts. It is the logical unit that applications and servers consume.

- Virtual disk
The volume is placed on a virtual disk. In SC Series, a virtual disk is a logical container that abstracts the underlying physical drives.

- Storage tier
Virtual disks are associated with a storage tier. Tiers group disks by performance characteristics, such as SSD, performance, or capacity.

- Disk folder
A disk folder is a grouping mechanism beneath the tier level that helps organize physical disks.

- Physical disk
At the bottom of the hierarchy are the actual physical drives that store the data.

In SC Series storage virtualization, the hierarchy moves from the logical object used by hosts down through layers of abstraction until it reaches the physical media. This allows the system to automatically manage placement, performance, and data distribution across different types of disks.

So the correct answer is A.

Quiz
