2V0-21.23 Question 20
Select 3A VMware vSphere administrator is configuring a storage array that supports VASA (vSphere APIs for Storage Awareness) to integrate with vSphere. The administrator wants to ensure proper multipathing for the datastore connections. Which of the following considerations should the administrator keep in mind to ensure optimal performance and availability?
- A
Ensure the storage array supports VASA and register it as a storage provider in vSphere.
- B
Configure the Path Selection Policy (PSP) to Round Robin for better load balancing across multiple paths.
- C
Disable VAAI (vSphere APIs for Array Integration) to avoid conflicts with VASA.
- D
Verify that the datastore is using a supported VMFS version for VASA.
- E
Use only one active path for all datastore traffic to simplify path management.
Show answer and explanation
Correct answers: A, B, D
Explanation
To ensure optimal performance and availability when configuring a VASA-supported storage array, it is critical to register it as a storage provider, configure the correct Path Selection Policy (e.g., Round Robin), and verify compatibility with the datastore's VMFS version. These steps ensure proper integration, load balancing, and utilization of storage array-specific features. Disabling VAAI or using only a single path would reduce functionality and create bottlenecks or risks of failure.
- A. Correct.
Registering the storage array as a storage provider using VASA is essential for vSphere to leverage storage-specific capabilities such as health monitoring, storage profiles, and alarms.
- B. Correct.
Using the Round Robin PSP helps balance the load across multiple paths, increasing performance and availability in multipathing configurations.
- C. Incorrect.
Disabling VAAI is unnecessary and counterproductive. VAAI works alongside VASA to enhance performance and offload certain operations to the storage array.
- D. Correct.
VASA requires the datastore to use a VMFS version supported by the storage array to ensure compatibility and functionality of advanced features.
- E. Incorrect.
Using only one active path for all traffic is not recommended as it creates a single point of failure and does not utilize the benefits of multipathing.
