2V0-21.23 Question 16
Select 3A company is experiencing performance issues with their storage environment in a VMware vSphere 8 infrastructure. They are using a storage array that supports vStorage APIs for Array Integration (VAAI). Which of the following benefits does VAAI provide to improve storage performance in such an environment?
- A
Reduces the load on ESXi hosts by offloading certain storage operations to the array
- B
Enables deduplication and compression on the ESXi host for better storage optimization
- C
Minimizes network traffic during storage-intensive operations like cloning or migration
- D
Improves the performance of virtual machine snapshots by leveraging array capabilities
- E
Allows direct communication between ESXi hosts and storage arrays without requiring a vCenter Server
Show answer and explanation
Correct answers: A, C, D
Explanation
VAAI (vStorage APIs for Array Integration) enhances storage performance by offloading tasks like cloning, zeroing, and snapshot optimizations to the storage array. This reduces the processing load on ESXi hosts and minimizes network traffic, resulting in improved efficiency and performance. It is important to note that VAAI does not handle deduplication/compression directly or eliminate the need for vCenter Server.
- A. Correct.
Correct. VAAI offloads certain storage operations, such as cloning and zeroing, to the storage array, reducing the burden on ESXi hosts and improving performance.
- B. Incorrect.
Incorrect. Deduplication and compression are typically handled by the storage array or specific software, not VAAI or the ESXi host.
- C. Correct.
Correct. VAAI minimizes network traffic during operations like cloning by directing these tasks to the storage array rather than sending data through the ESXi host.
- D. Correct.
Correct. VAAI leverages array capabilities to optimize snapshot-related operations, improving their performance.
- E. Incorrect.
Incorrect. While VAAI enhances communication between ESXi hosts and the array for specific tasks, it does not replace the need for vCenter Server or establish direct communication outside its specific operations.
