VMware 3V0-21.23 Exam - Topic 3 Question 23 Discussion

An architect is designing a new vSphere solution. The customer has provided the following information to describe how the solution will be used:The solution will host development workloadsAdministrators will utilize snapshots frequently, with snapshots sometimes retained for extended periods of timeSome of the workloads are sensitive to latency on the I/O of the storageStorage for the workloads will be provided by a physical arrayThe physical array does not include a storage providerAll workloads must be hosted on the solution, there are no other vSphere environments available for useWhich design decision should the architect make to meet the needs of the customer?
A) Use a storage array which supports VMware vSphere APIs: Array Integration (VAAI) to configure VMFS datastores for the workloads
B) On workloads which will use snapshots, set the latency-sensitivity=high advanced setting
C) Use a storage array which supports vSphere Storage APIs - Storage Awareness (VASA) to configure Virtual Volumes (vVols) datastores for the workloads
D) On workloads which are sensitive to latency, set the latency-sensitivity=high advanced setting

[All 3V0-21.23 Questions]

An architect is designing a new vSphere solution. The customer has provided the following information to describe how the solution will be used:

The solution will host development workloads

Administrators will utilize snapshots frequently, with snapshots sometimes retained for extended periods of time

Some of the workloads are sensitive to latency on the I/O of the storage

Storage for the workloads will be provided by a physical array

The physical array does not include a storage provider

All workloads must be hosted on the solution, there are no other vSphere environments available for use

Which design decision should the architect make to meet the needs of the customer?

Show Suggested Answer Hide Answer
Suggested Answer: A

VAAI (vSphere APIs for Array Integration) improves storage performance and offloads certain tasks (such as cloning, snapshots, and more) directly to the storage array. This is important because the customer will be utilizing snapshots frequently, and VAAI can help accelerate snapshot operations, reducing the impact on the ESXi host and improving overall performance.

Since the physical array does not include a storage provider and does not support vSphere Storage APIs - Storage Awareness (VASA) or Virtual Volumes (vVols), the solution should focus on using VMFS datastores with a VAAI-capable storage array. This setup allows better performance for snapshot operations and other storage tasks.

B might help, but I’d be cautious with long snapshot retention.

Surprised there's no storage provider included! How will that work?

I think D makes more sense for latency-sensitive workloads.

Option A is the best choice for VAAI support.

I feel like the physical array's lack of a storage provider might limit our options. Maybe we should focus on the advanced settings for latency-sensitive workloads instead.

This question seems similar to one we practiced where we had to choose between VAAI and VASA. I think VAAI is more relevant for this scenario since snapshots are frequently used.

I'm a bit unsure about the advanced settings. I think setting latency-sensitivity to high could help, but I’m not sure if that’s the best approach for all workloads.

I remember we discussed the importance of VAAI for improving storage performance, especially with snapshots. That might be a good option here.
