Network Attached Storage (NAS)

Question 1

What is NAS?

Answer 1

NAS is a dedicated file-level storage system connected to a network, allowing multiple devices to access and share files over the network.

Question 2

How is NAS vs SAN different?

Answer 2

NAS provides file-level storage over a network, while SAN offers block-level storage, making NAS easier to deploy and manage, but generally less performant for high-speed transactional workloads.

Question 3

What type of data does a NAS typically handle?

Answer 3

NAS handles file-level data, meaning the data is stored in files, with the file system managing how data is stored and accessed.

Question 4

What is file-level data?

Answer 4

File-level data means data is stored as complete files, organized in directories and managed by a file system (like NTFS, NFS, or SMB). It’s more structured and easier to manage for end-users.

Question 5

What are the benefits of file-level storage?

Answer 5

Easier to manage, better for sharing files, simpler for file collaboration, and less complex than block-level storage. Ideal for general-purpose storage needs.

Question 6

What are common workloads that benefit from NAS storage?

Answer 6

File sharing (e.g., between users or workgroups)

Backup and archival

Media storage (videos, photos, audio)

Document management

Home directories

Collaboration platforms (e.g., SharePoint, Google Drive-like systems)

Question 7

What are the main protocols used in NAS environments?

Answer 7

NFS (Network File System)

SMB (Server Message Block) / CIFS (Common Internet File System)

AFP (Apple Filing Protocol)

HTTP/HTTPS (in some cases for web-based access)

Question 8

How does NAS compare to SAN in terms of use cases?

Answer 8

NAS: Best suited for file sharing, backup, collaboration, and general-purpose storage.

SAN: Better for high-performance, transactional workloads like databases, virtualized environments, and mission-critical applications.
