1. Understanding the Requirement:
The storage must support deduplication and backup policy management.
The solution must be virtualized and separate from data VMs, ensuring flexibility and centralized management.
2. Analyzing the Options:
A . Software-defined storage:
Correct. SDS abstracts storage resources from hardware, allowing for centralized deduplication, backup policies, and dynamic scalability. Ideal for pre-cloud deployment. ✅ B . Containerized storage:
Incorrect. Containerized storage focuses on ephemeral data storage for containerized applications, not ideal for deduplication or backups. ❌ C . Thick-provisioning storage:
Incorrect. Thick provisioning allocates fixed storage size but lacks deduplication and backup management features. ❌ D . RAID 10 disk-array storage:
Incorrect. RAID 10 provides fault tolerance and performance but is hardware-centric and does not address deduplication or centralized backup management. ❌
3. Why SDS is Ideal:
SDS enables policy-driven management for backups, snapshots, and data deduplication.
Supports seamless integration with cloud environments, facilitating migration.
