HP0-J73 Question #169: Real Exam Question with Answer & Explanation
The correct answer is B: storage device level. Storage device-level virtualization, implemented within the storage array's own controllers, delivers the best balance of performance, flexibility, capacity, and manageability.
Question
Which level of storage virtualization implementation offers the best combination of flexibility, performance, capacity, and ease of management?
Options
- ASAN switch level
- Bstorage device level
- Cnetwork level
- Dserver level
Explanation
Storage device-level virtualization, implemented within the storage array's own controllers, delivers the best balance of performance, flexibility, capacity, and manageability.
Common mistakes.
- A. SAN switch-level virtualization introduces processing overhead in the network fabric and can create bandwidth bottlenecks that limit performance for high-throughput storage workloads.
- C. Network-level virtualization adds latency by intercepting and processing storage operations outside the array, reducing performance compared to array-native approaches.
- D. Server-level virtualization consumes host CPU and memory for storage management tasks, degrading application performance on the server and limiting scalability across heterogeneous storage environments.
