What are the advantages of object storage over traditional NAS storage? (Select all that apply)

AHTTP/HTTPS is more universal than NFS/CIFS and supports Internet access.

BCustomized metadata is easy to manage.

CTree-shaped directories and hierarchical management are easy to understand.

DThe flat structure is easy to expand.

Show Suggested Answer

Suggested Answer: A, B, D

Huawei documentation highlights several key advantages of object storage for modern data requirements. Option A is correct because object storage primarily uses RESTful APIs (HTTP/HTTPS), which are firewall-friendly and accessible globally over the internet, unlike NFS/CIFS/SMB which are generally restricted to local area networks (LANs).

Option B is correct because object storage allows for extensible metadata. Users can attach custom tags to objects, enabling powerful data searching and automated lifecycle management without needing an external database to track file attributes. Option D is correct because object storage uses a flat namespace rather than the tree-shaped directory structure of NAS. In a flat structure, adding more nodes to the system does not increase the complexity of data retrieval, allowing for nearly infinite horizontal scalability. Option C is incorrect in this context because the tree-shaped directory is actually a limitation of NAS that causes performance degradation at high scales, whereas object storage avoids this hierarchy to improve expansion capabilities.

Wait, is it really that much better than NAS? Sounds too good to be true.

Customized metadata? Sounds like a fancy way to say "you can name your files whatever you want."

I feel like A and B are solid choices, but I’m not convinced about C being an advantage. Isn’t the hierarchical structure more intuitive?

D seems right to me; the flat structure does make it easier to scale, but I’m a bit confused about how that compares to traditional NAS.
